Answer:
x=-6/29
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(3x+2)−2=2(1−7x)
(5)(3x)+(5)(2)+−2=(2)(1)+(2)(−7x)(Distribute)
15x+10+−2=2+−14x
(15x)+(10+−2)=−14x+2(Combine Like Terms)
15x+8=−14x+2
15x+8=−14x+2
Step 2: Add 14x to both sides.
15x+8+14x=−14x+2+14x
29x+8=2
Step 3: Subtract 8 from both sides.
29x+8−8=2−8
29x=−6
Step 4: Divide both sides by 29.
29x/29=-6/29
x=-6/29

Answer:
x = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let the third side be x , then
x² + 8² = 10²
x² + 64 = 100 ( subtract 64 from both sides )
x² = 36 ( take the square root of both sides )
x = [tex]\sqrt{36}[/tex] = 6
Answer:
6
Step-by-step explanation
Ordered triples only apply to right triangles
3,4,5 is an ordered triple
multiply (3,4,5) by 2 and you get (6,8,10)
the 2 other side lengths are 8 and the hypotenuse is 10 then the other side length is 6.
-------------------
That is just a way to do it quickly and it does not always apply.
the formula for Pythagorean and theorem is a^2+b^2=c^2
a=leg of the triangle
b=other leg of teh triangle
c=hypotenuse(longest leg)
as we can see here 10 is the longest so it is the hypotenuse.
So then we can assume that 8 is a leg of the triangle
so we insert that into the equation
a^2+8^2=10^2
subtract 8^2 from both sides
a^2=10^2-8^2
a^2=100-64
a^2=36
square root both sides
a=√(36)
a=6

Annabelle has 56 1 cm³ what are the dimensions of the rectangle Langer prism Annabelle could build with all the cubes
Answer:
The six possible rectangular prisms Anabelle could build are;
W = 1, B = 1, L = 56
W = 1, B = 2, L = 28
W = 1, B = 4, L = 14
W = 2, B = 2, L = 14
W = 1, B = 7, L = 8
W = 2, B = 4, L = 7
Step-by-step explanation:
The number 1 cm³ Annabelle has = 56
The dimensions volume of the cubes Annabelle could build with the 1 cm³ = 56 cm³
The volume of rectangular prism, V = L × B × W
∴ For the rectangular prism, V = 56 cm³ = L × B × W
Therefore, the possible dimensions of the prism are three factors of 56, including;
1, 2, 4, 7, 8, 14, 28, 56
The combination of 3 factors of 56 that can be multiplied together to give 56 and therefore, the possible rectangular prisms includes;
W × L × B = A
1) 1 × 1 × 56 = 56
2) 1 × 2 × 28 = 56
3) 1 × 4 × 14 = 56
4) 2 × 2 × 14 = 56
5) 1 × 7 × 8 = 56
6) 2 × 4 × 7 = 56
There are therefore 6 possible rectangular prisms Annabelle could build

Determine the vertical asymptotes and holes for the graph of the equation below.
y=[tex]\frac{x+7}{x^2+8x+7}[/tex]
Please show all steps to solve!
Since x ² + 8x + 7 = (x + 7) (x + 1), we have for x ≠ -7,
y = (x + 7) / (x ² + 8x + 7) = 1/(x + 1)
so y is undefined at x = -1, indicating a vertical asymptote, and there is a hole/removable discontinuity at x = -7. Then the answer is D.

The list price on a winter coat is $84. It is being sold at a 23% discount. What is the sale price of the coat?
A)$64.68
B)$61.32
C)$47.48
D)$22.68
Answer:
A) $64.68
Step-by-step explanation:
Note that 23% = 23/100 = 0.23
First, multiply $84 with 0.23:
84 x 0.23 = 19.32
Next, subtract 19.32 from the total cost:
84 - 19.32 = 64.68
A) $64.68 is your answer.

Answer:
Step-by-step explanation:
Alex bought a new skate board at 20% discount. He paid $72. What percent of the original price did he pay?
Step 1
We find the original price
= Percent Discount × Original price =
= 20% × Original price = $72
= 0.2 × x = $72
x = $72/0.2
x = 360
Continue to name one point that is a solution to the
inequality and one point that is not a solution.
y ≤ 3x + 4
Answer:
y≤6x+8
Step-by-step explanation:
Given function:
y≤3x+4This means:
variable stays same
if y=7 then x=1 and if y=14 then x can be 2 or 3.
we can also think as:
y≤6x+8
what we did:
double the number: 3x+4 · 2 = 6x+8
Therefore, another equation for y≤3x+4 would be y≤6x+8.
