Solve the following equation:
4(x−3)=48−8x
A. x = 5
B. x = 12
C. x = 60
D. x = -5
Answer:
The answer is A
Step-by-step explanation:
4(x-3=)=48-8x
4(5-3)=48-8*5
20-12=8 48-40=8
8=8
Hope this answers your question
Answer: x =5 4x-12=48-8x add 12 to both sides 4x-12+12=48-8x+12 Simplify 4x=-8x+60 add 8× to both sides 4x+8x=-8x+60+8x Simplify 12x=60 Divide both sides by 12 f{12x}{12}={60}{12} x=5

1. Using the following dilated coordinates of a triangle choose the appropriate scale factor.
J:(2.4)---J':(4,8)
K:(1,1)----K':(2,2)
L:(4.0)----L':(8,0)
A.5
B.4
C.3
D.2
Answer:
2
Step-by-step explanation:
The scale factor is 2. So, the correct option is D.
Important information:
[tex]J(2,4)\to J'(4,8)[/tex][tex]K(1,1)\to K'(2,2)[/tex][tex]L(4,0)\to J'(8,0)[/tex]We need to find the scale factor.
Scale factor:If a figure is dilated by factor [tex]k[/tex] with origin as the center of dilation, then
[tex]P(x,y)\to P'(kx,ky)[/tex]
Using this rule, we get
[tex]J(2,4)\to J'(2k,4k)[/tex]
We have [tex]J'(4,8)[/tex]. So,
[tex]J'(2k,4k)=J'(4,8)[/tex]
On comparing both sides, we get [tex]2k=4[/tex] or [tex]4k=8[/tex]. In both cases, the value of scale factor is [tex]k=2[/tex].
Thus, the correct option is D.

The amount of oil used in four different recipes is shown in the table.
Recipe
Oil
Bread
2/8 cup
Cookies
1/3 cup
Cake
1/5 cup
Pie
1/7 cup
Which recipe uses the most oil?
bread
cookies
cake
pie
Answer:
The cookie recipe uses the most oil.
Step-by-step explanation:
In order to solve this problem, you must convert all of these fractions into decimals.
Bread: 2/8 cup = 0.25 cup or 1/4 cup
Cookies: 1/3 cup = 0.33 cup
Cake: 1/5 cup = 0.2 cup
Pie: 1/7 cup = 0.14 cup
Therefore, the cookie recipe uses the most oil.

1/20 Ella runs at a speed of __________ miles per hour.
Blank 1: ______________
Part B
Ella's father spent $20 on ice cream for the family. He had to pay a 7% sales tax. What was the total cost of the ice cream? $
*Hint: be sure to include 2 decimal places to show the cents*
Blank 2: __________________
PLEASE DONT ANSWER IDK OR SOMETHING LIKE THAT JUST FOR POINTS PLEASE!
Answer:
Elena's running speed is 5 miles/hour
Explanation:
The speed is defined as the covered distance per unit time
In the problem, we have:
The distance covered is the length (circumference) of the circular track which is given as of a mile.
We are also given that she completes each lap (she completes of a mile) in of an hour
To get her speed, we will divide the distance covered by the time taken to cover this distance
This is done as follows:
speed = miles/hour
This means that:
Elena can run 5 miles each hour

Write an equation for the following graph.
Answer:
y = 25x
Step-by-step explanation:
slope is 25 because to move from one point to another (on the line) you move up 50 (from 0 to 50) and to the right 2 (from 0 to 2) slope is 50/2 which simplified to 25
when x = 0, y = 0 so the y intercept is 0 but it isn’t necessary to add it to the equation
Answer:
y=25x
Step-by-step explanation:
Consider this equation.
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
Mia solved the equation and determined that m = 2. Is she correct?
Answer:
No, Mia is not correct, the answer is -2.
Step-by-step explanation:
First we are going to use the distributive Property.
Step 1: 2(0.75+0.4). multiply the 2 out. .75m x 2=1.5m and 2 x .4= .8.
We get 1.5m+.8, so 2(0.75+0.4)=1.5m+.8
Now we are going to distribute on the oher side. 4(.5m-.8)
4x .5m=2m and 4x.8=3.2. Keep the sign the same and we get 2m-3.2, so 4(.5m-.8)=2m-3.2
We put this into the new equation to get 1.5m+.8+7.8=-6.4m+2m-3.2
Step 2: combine like terms
.8+7.8= 8.6 and -6.4m +2m =-4.4m
Plug that into our equation and we get 1.5mn+8.6=-4.4m-3.2
Step 3: Switch the sides
Bring -4.4m to the other side to get 1.5m+4.4m=5.9m
One side is 5.9m
We bring 8.6 to the other side to get -8.6. now we do -3.2-8.6=-11.8.
Our new equation is 5.9m=-11.8
divide by 5.9 on both sides to get our answer of
m=-2
