Answer:
Her room is 90 inches.
Step-by-step explanation:
1/2 x 6 = 3
If we multiply 1/2 by 6, then we must do the same to 15.
15 x 6 = 90.

Step-by-step explanation:
is the equation y = 3x + 1 proportional or non proportional?
Answer:
non- proportional
Step-by-step explanation:
a proportional equation is in the form of y=kx, not y = mx + b like this one :)
The equation y = 3x + 1 is a non-proportional equation.
What is proportional relationship?A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well.
Given:
The equation y = 3x + 1.
The proportional relationship:
Generally, it is represented as y/x = k, where x and y are two expressions and k is constant.
y/x = k
Simplifying,
y = kx.
This is a representation of linear proportionate equation.
And the given equation is not in the required form.
Therefore, y = 3x + 1 is a non-proportional linear equation.

What is the volume of two cubes with a side length of 1/2 foot? V = s^3, where s is the side length.
1/2 ft^3
1/4 ft^3
1/8 ft^3
1/9 ft^3
Answer:
So the answer should be 1/4.
Step-by-step explanation:
so a cube has all equal sides and volume is equal to s^3 or side*side*side in this case 1/2*1/2*1/2. There are two cubes so you would multiply that by two creating 2*1/2*1/2*1/2
Hope this helps :)

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

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

50 points and brainliest for the first CORRECT answer!!!!!!!!!!!!!!!!!!!!!!!!!!!! Rodney is given two linear equations: x – y = 11 and 2x + y = 19. What is the value of x in the solution to the system of equations?
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
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.
