The solution to the equation takes the form a/2+b, where, a = -4 and b= -3, is 4 or -5 depending on the equation used.
What is the substitution of variables into an equation?The substitution of variables takes a defined pattern. In the given question, we are to replace the following values for a and b. i.e. a = -4 and b = -3 into the equation a/2+b.
So,
If a = - 4;and b = -3Then, using the expression:
[tex]\mathbf{=\dfrac{a}{2+b}}[/tex]
The solution to the equation can be calculated as:
[tex]\mathbf{=\dfrac{-4}{2+(-3)}}[/tex]
[tex]\mathbf{=\dfrac{-4}{-1}}[/tex]
Divide both the numerator and denominator by (-1)
= 4
However, if the equation is [tex]\mathbf{\dfrac{a}{2}+b}[/tex]
The solution to the equation will be as follows:
[tex]\mathbf{\dfrac{-4}{2}+(-3)}[/tex]
= -2 - 3
= -5

What are the values of x and y?
Answer:
Y=45 X=90
Step-by-step explanation:
B is equal to C so it would be 45. Since the whole triangle must be 180 you subtract 45 and 45 from 180 and you get 90. Another way to tell C and B are the same is the 2 little lines on the sides.
Answer:
y=45°(angles opposite to equal sides are equal)
x+y+45=180(sum of the interior angles of a triangle is 180)
x+45+45=180
y+90=180
y=180-90
y=90

Tom host a new program the kitchen gladiator, wants to mix a dip containing 5% horseradish with one containing 20% horseradish to obtain a 24 ounce dip containing 10% horseradish, how many ounces of the 5% dip should he use?
Answer:
16 ounces
Step-by-step explanation:
x, quantity of the 5%
24-x, quantity of the 20%
5%x + 20%(24-x) = 10% of 24
.05x + .20(24-x) = .10 * 24
.05x + 4.8 - .20x = .10 * 24
4.8 -.15x = 2.4
2.4 = .15x
.15x = 2.4
x = 2.4/.15
x = 16

Hailey went to Frank's Market and bought 1 3/4 pounds of coffee at $13 a pound and 8 1/2 pounds of rice at $0.45 pero pound. If Hailey paid with a $50 Bill how much chance did she receive?
Answer: She received $18.42 as change.
Step-by-step explanation:
Given: Cost of coffee per pound = $13
[tex]1\dfrac34[/tex] pounds of coffee costs [tex]=1\dfrac34\times 13=\dfrac{4+3}{4}\times 13[/tex]
[tex]=\dfrac74\times 13\\\\=\$ 22.75[/tex]
Cost per pound of rice = $0.45
[tex]8\dfrac12[/tex] pounds of rice costs = [tex]8\dfrac12\times 0.45=\dfrac{17}{2}\times0.45[/tex]
[tex]=\$3.825[/tex]
Bill amount = $ (22.75+8.825) = $ 31.575≈ $31.58
If Hailey paid $50, then she will receive = $(50-31.58)
= $ 18.42
Hence, She received $18.42 as change.
Answer: She received $18.42 as change.
Step-by-step explanation:
Given: Cost of coffee per pound = $13
pounds of coffee costs
Cost per pound of rice = $0.45
pounds of rice costs =
Bill amount = $ (22.75+8.825) = $ 31.575≈ $31.58
If Hailey paid $50, then she will receive = $(50-31.58)
= $ 18.42
Hence, She received $18.42 as change.
Find the surface area of the figure below.
Answer:
108 i think
Step-by-step explanation:
Answer:
108 inch.
Step-by-step explanation:
To make it a bit easier, I calculated the area of each side of the prism that was shown.
1. Start with the triangular sides: 3 × 4/2 = 6. Since there are two triangular surfaces, you add them together. In the end, you have 12 inch.
2. Calculate the surface with the dimensions 8 in. with 5 in.: 8 × 5 = 40 inch.
3. Calculate the surface with the dimensions 4 in. with 8 in.: 4 × 8 = 32 inch.
4. Calculate the surface with the dimensions 3 in. with 8 in.: 3 × 8 = 24 inch.
5. Last step - add all the results together: 12 + 40 + 32 + 24 = 108 inch.

The figure shown consists of a square pyramid on top of a square prism. The surface area of the figure is 432 cm2. The height of the prism is three times the height of the pyramid.
Find the heights of the pyramid and the prism.
The height of the pyramid is
cm.
The height of the prism is
cm.
Answer:
height of pyramid = 3 cm
height of prism = 9 cm
Step-by-step explanation:
Square Pyramid
surface area of 4 triangular sides of the pyramid = [tex]2a\sqrt{\dfrac{a^2}{4}+h^2}[/tex]
(where [tex]a[/tex] is the base edge and [tex]h[/tex] is the height)
Given [tex]a[/tex] = 8 cm
[tex]\implies \textsf{SA}=2\cdot8\sqrt{\dfrac{8^2}{4}+h^2}[/tex]
[tex]=16\sqrt{16+h^2}[/tex]
Square Prism
surface area of square prism with one base = [tex]a^2+4ah[/tex]
(where [tex]a[/tex] is the base edge and [tex]h[/tex] is the height)
Given [tex]a[/tex] = 8 cm and [tex]h[/tex] = 3h
[tex]\implies \textsf{SA}=8^2+4\cdot 8\cdot 3h[/tex]
[tex]=64+96h[/tex]Total surface area
total SA = SA of pyramid + SA of square prism
Given total SA = 432 cm²
[tex]\implies 432=16\sqrt{16+h^2}+64+96h[/tex]
[tex]\implies 368=16\sqrt{16+h^2}+96h[/tex]
[tex]\implies 368=16(\sqrt{16+h^2}+6h)[/tex]
[tex]\implies 23=\sqrt{16+h^2}+6h[/tex]
[tex]\implies 23-6h=\sqrt{16+h^2}[/tex]
[tex]\implies (23-6h)^2=16+h^2[/tex]
[tex]\implies 529-276h+36h^2=16+h^2[/tex]
[tex]\implies 35h^2-276h+513=0[/tex]
[tex]\implies (h-3)(35h-171)=0[/tex]
[tex]\implies h=3, h=\dfrac{171}{35}[/tex]
Inputting both values of [tex]h[/tex] into the equations for SA:
when [tex]h = 3[/tex]:
[tex]\textsf{pyramid}=16\sqrt{16+3^2}=80 \ \sf cm^2[/tex]
[tex]\textsf{square prism}=64+96(3)=352 \ \sf cm^2[/tex]
[tex]\textsf{total SA}=80+352=432 \ \sf cm^2[/tex]
when [tex]h=\dfrac{171}{35}[/tex]:
[tex]\textsf{pyramid}=16\sqrt{16+(\frac{171}{35})^2}=101.0285714... \sf cm^2[/tex]
[tex]\textsf{square prism}=64+96(\frac{171}{35})=533.0285714... \ \sf cm^2[/tex]
[tex]\textsf{total SA}=101.0285714...+533.0285714... =634.0571428... \ \sf cm^2[/tex]
Therefore, h = 3 only (since the total area is 432 cm²)
⇒ height of pyramid = 3 cm
⇒ height of prism = 3h = 3 × 3 = 9 cm

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options.
a.18 x minus 15 = 72
b.50 x minus 25 = 72
c.18 x minus 9 = 72
d.3 (6 x minus 3) = 72
e.x=4.5
Answer:
C, D and E
Step-by-step explanation:
Given equation:
[tex]\dfrac35(30x-15)=72[/tex]
Use the distributive law [tex]a(b-c)=ab-ac[/tex]:
[tex]\implies \dfrac35\cdot30x- \dfrac35\cdot15=72[/tex]
[tex]\implies \dfrac{3 \cdot30}5x- \dfrac{3 \cdot15}5=72[/tex]
[tex]\implies \dfrac{90}5x- \dfrac{45}5=72[/tex]
[tex]\implies 18x- 9=72[/tex] ← option c
Factor out common term 3:
[tex]\implies 3(6x- 3)=72[/tex] ← option d
Solve [tex]18x- 9=72[/tex]:
[tex]\implies 18x- 9+9=72+9[/tex]
[tex]\implies 18x=81[/tex]
[tex]\implies \dfrac{18x}{18}=\dfrac{81}{18}[/tex]
[tex]\implies x=4.5[/tex] ← option e

mom bought a dress for 320 dollars during the big sale its original price is 400 yuan how much is the discount
Answer:
20% discount
Step-by-step explanation:
Given the following question:
20% of 400
To find the answer we will use the formula to calculate percentages, once we have that answer we then subtract it from the original price to see if we have the same new price as the question.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{20\times40}{100}[/tex]
[tex]20\times40=8000[/tex]
[tex]8000\div100=80[/tex]
[tex]=80[/tex]
Subtract from the original price:
[tex]400[/tex]
[tex]400-80=320[/tex]
[tex]=320[/tex]
The dress has a "20% discount."

What are permutation and combination?A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Anita has a costume wardrobe that consists of 2 pairs of tights (1 white pair and 1 black pair), 3 T-shirts (1 pink, 1 blue, and 1 green), and 3 scarves (1 silver, 1 gold, and 1 white).
The costume consists of either a pair of tights or a T-shirt with a scarf:
In this case total number of ways = 2×3×3 = 18
Pair of tights and a T-shirt without a scarf:
In this case total number of ways = 2×3 = 6
Total number of different costumes are possible:
= 18 + 6
= 24
Thus, the total number of different costumes possible is 24 if Anita has a costume wardrobe that consists of 2 pairs of tights, 3 T-shirts, and 3 scarves.

4.1 Provide with reason 6 angles that are equal to x
Step-by-step explanation:
1. ∠EBC = x (Theorem One: The angle at the centre of the circle is twice the angle at the circumference subtended on the same arc. You already have this one labelled)
2. ∠FCD = x (F rule / corresponding angles are equal)
3. ∠CAE = x (Theorem Two: Angles at the circumference subtended by the same arc are congruent)
4. ∠BED = ∠DCF = ∠FCD = x (Theorem Fifteen: The exterior angle of a cyclic quadrilateral is congruent to the interior opposite angle)
5. ∠CDF = ∠BED = x (F rule / corresponding angles are equal)
6. ∠CAE = ∠OAE = ∠OEA = x (CAE and OAE are the same angles, OF and OA are radii, thus they must both be equivalent in magnitude, therefore making the triangle ΔAOE isosceles. Base angles of an isosceles triangle are always equal, since we knew ∠OAE from '3.' was x, we found that ∠OEA was also x)
If you want to buy an item in a store that costs $50 and is on sale for 10% off, then
how much would the item actually cost you after the discount? Round to the nearest
cent.
Answer:
It would be $45.00.
Step-by-step explanation:
50 divided by 10 would be 5. Subtract that from 50 to get 45.
Answer:
$45.00
Step-by-step explanation:
If an item cost $50 and the discount is 10% then:
Convert 10% to a decimal
10/100 = .1
.1 * $50 = $5
The discount is $5, subtract the discount from the original amount.
$50 - $5 = $45
The item would cost $45.00 after the discount.
