#TheWizzer
Answer: 40 cars pass per minute.
Step-by-step explanation:
[tex]\frac{120cars}{3minutes\\}[/tex] = [tex]\frac{?cars}{1minutes}[/tex]

What is the solution of the equation 6x - 4 = 2(3x - 2). Explain your steps.
Answer: x= 4/3 but in decimal form =1.333
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4-(2*(3*x-2))=0
4 - 2 • (3x - 2) = 0
Pull out like factors :
8 - 6x = -2 • (3x - 4)
Solve : 3x-4 = 0
Add 4 to both sides of the equation :
3x = 4
Divide both sides of the equation by 3:
x = 4/3 = 1.333
Answer:
x= undefined
Step-by-step explanation:
In order to make u understand , if u multiply 2(3x-2) it becomes 6x-4 which is the exact same as the left hand side . Therefore u cant find x from here in this manner .
For this however we can try the method bellow .
Lets say f(x)=y=6x-4=2(3x-2)
we can get the followig points for inserting domains and finind the domains . we can make graph for each . (We will not do them however)
As we have seen that both of those parts of the equation are one and the same so they will produce the exact same Line or curve .
Therefore every signle points on them r the same exact points and there fore they are the same exact line .
So the value of x is undefined and can be anything between every points on that line (Which can be infinit amounts of points) .
calculate the rate of change from the graph below
Answer:
The rate of change is 0.75 gallons per minute
Step-by-step explanation:
The rate of change of the linear relation is represented by the slope of the line which represents this relation
The rule of the slope of a line is
m = Δy/Δx, where
Δy is the vertical changeΔx is the horizontal changeFrom the given graph
∵ The line passes through points (0, 0) and (4, 3)
∴ Δx = 4 - 0 = 4
∴ Δy = 3 - 0 = 3
→ Use the rule of the slope above to find the slope of the line
∴ m = [tex]\frac{3}{4}[/tex] = 0.75
∵ The x-axis represents the time in minutes
∵ The y-axis represents the amount in gallons
∵ m represents the rate of change
∴ The rate of change = 0.75 gallons per minute
Emma buys a house for £300,000. She sells the house for £315,000. Calculate the percentage profit Emma makes
She buys it for £300,000 and sell it for £315,000 -> she profits £15,000.
So, the percentage profit Emma makes is : 15,000 : 300,000 = 0.05 -> 5%.
Answer:
5%
Step-by-step explanation:
300000 = 100%
1% = 300000 ÷ 100 = 3000
She made 15000
15000 ÷ 3000 = 5%

Review Question: 5) f(x) = 2xsquared + 7x - 15 find f(-8)
Answer:
f(-8) = 57
Step-by-step explanation:
When x = - 8
f(-8) = 2 x (-8)² + 7 x (-8) - 15
f(-8) = 2 x 64 - 56 - 15
f(-8) = 128 - 56 - 15
f(-8) = 128 - 71
f(-8) = 57
[tex]\sf f(x) = 2x^2 + 7x - 1[/tex]
Just substitute the value of x as (-8) .
[tex]\sf f(-8) = 2(-8)^2 + 7(-8) - 15[/tex]
[tex]\sf f(-8) = 2(64) - 7(8) - 15[/tex]
[tex]\sf f(-8) = 128 - 56 - 15[/tex]
[tex]\sf f(-8) = 128 - 71[/tex]
[tex]\sf f(-8) = 57[/tex]

To make a big batch of cookies for her father, Annmarie needs 1 1 4 pounds of chocolate chips, 3 4 pounds of walnuts, and 12 ounces of raisins. How many ounces of these three ingredients does she need in all?.
She will need 68 ounces in total for all three ingredients.
What will be the total ounces for all three ingredients?It is given that
For chocolate chips, she has = [tex]\dfrac{11}{4}[/tex] pounds
For walnuts, she has = [tex]\dfrac{3}{4}[/tex] pounds
For raisins, she has= 12 ounces
We know that,
[tex]\rm 1 \ pound = 16 \ ounces[/tex]
[tex]\rm For \ chocolate \ chips, she\ has = \dfrac{11}{4} \times 16 }=44 \ ounces[/tex]
[tex]\rm For \ walnuts,\ she\ has = \dfrac{3}{4} \times 16 }=12\ ounces[/tex]
[tex]\rm For\ raisins, she \ has= 12\ ounces[/tex]
so the total number of ounces she has will be the sum of all
[tex]=44+12+12 =68\ ounces[/tex]
Thus she will need 68 ounces in total for all three ingredients.

c)120
d)74
e)87
Answer:
m∠JTS = 104° ⇒ (A)
Step-by-step explanation:
The measure of an exterior angle of a triangle at one of its vertices equals the sum of the measures of the opposite interior angles.
Let us use this fact to solve the question
In ΔTSR
∵ T ∈ ray RJ
∴ ∠JTS is an exterior angle of ΔTSR
→ By using the fact above
∴ ∠TSR and ∠TRS are the opposite interior angles to ∠JTS
∴ m∠JTS = m∠TSR + m∠TRS
∵ m∠JTS = 27x - 4
∵ m∠ TSR = 30°
∵ m∠TRS = 18x + 2
→ Substitute their values in the equation above
∴ 27x - 4 = 30 + 18x + 2
→ Add the like terms in the right side
∴ 27x - 4 = 18x + 32
→ Add 4 to both sides
∴ 27x = 18x + 36
→ Subtract 18x from both sides
∴ 9x = 36
→ Divide both sides by 9
∴ x = 4
→ To find m∠JTS substitute x by 4 in its measure
∴ m∠JTS = 27(4) - 4 = 108 - 4
∴ m∠JTS = 104°

Answer:
x = 33°
explanation:
The interior angles sum up to 180°
solve:
x + 20° + 4x - 5° = 180°
x + 4x + 20° - 5° = 180°
5x + 15° = 180°
5x = 180° - 15°
5x = 165°
x = 33°
Answer:
x = 33
Step-by-step explanation:
Sum of consecutive interior angles = 180°
⇒ (x + 20) + (4x - 5) = 180
⇒ 5x + 15 = 180
⇒ 5x = 165
⇒ x = 33

Jane is helping the librarian stack books on some new shelves. She is to stack 116 books on 16 shelves. The librarian told her to put the same number of books on each of the 16 shelves. Describe a different way that Jane can use to determine the number of books she should put on each shelf.
Answer: The number of books she should put on each shelf = 7
Step-by-step explanation:
Given: Total books = 116
Total shelves = 16
To determine : The number of books she should put on each shelf, we first divides the total number of books by the total shelf.
[tex]116\div 16=7\dfrac14[/tex]
So she can put 7 books in each shelf such that (7x16=) 112 books got placed and (116-112=)4 books left.
Hence, The number of books she should put on each shelf = 7.

The length of a rectangle is 5 more than twice the width. If the perimeter of th

The length of a rectangle is 5 more than twice the width. If the perimeter of the rectangle is 34 cm find the length?
Explanation -:In this question we are provided with the perimeter of the rectangle = 34 cm and it is given that the length of the rectangle is 5 more than the twice it's breadth and asked to find out the length of the rectangle.
[tex] \small \orange{ \underline{\rm \blue{length \: of \: a \: rectangle \: is \: 5 \: more \: than \: twice \: the \: width.}}}[/tex]
Let us assume breadth as x then length = 2x +5
We know,
[tex] \star \: \large\boxed{ \rm{ Perimeter_{(rectangle)} = 2(length + breadth)}}[/tex]
Substituting the values we get
34 = 2(2x +5 + x)
→ 34 = 2(3x + 5)
→ 34 = 6x + 10
→ 34 - 10 = 6x
→ 24 = 6x
→ [tex]\dfrac{24}{6}[/tex] = x
x = 4
Length = 2x + 5 = 2 × 4 + 5 = 8 + 5 = 13 cm
Breadth = x = 4cm
Length = 13 cm.
