There are 6 surfaces on a rectangular prism . 3 pairs of equal area.
Surface area 2wl + 2hw + 2 hl where h = height, w = width, l = length.
So inserting the given values:-
442 = 2*w*11 + 2 *8* w + 2*8*11
442 = 22w + 16w + 176
38w = 442-176 = 266
w = 7
width = 7 feet
1. The Associative Property of Addition.
Both equations equal 28.
2. The equations are not equal.
Answer: 1 cup of sugar
Step-by-step explanation:
A recipe for banana bread requires 3 cups of bananas for every 1 1/2 cups of sugar used.
Converting 1 1/2 cups of sugar to improper fraction becomes 3/2 cups of sugar.
If 3 cups of bananas is required for 3/2 cups of sugar,
x cups of bananas will require 1 cup of sugar
3x / 2 = 3
3x = 6
x = 6/3 = 2
Therefore,
2 cups of bananas will require 1 cup of sugar.
We are looking for the number of cups of sugar that would require 2 cups of bananas.
We already got the answer.
1 cup of sugar would be used if 2 cups of bananas are used.
Answer:
(3,1) --> One solution
Step-by-step explanation:
Start by multiplying the first equation by 4:
-7x(4)+2y(4)=-19(4)
-28x+8y=-76
In this scenario, we can eliminate 8y by subtracting the two equations:
-34x=-102
Divide both sides by -34
x=3
Plug 3 back in for x to solve for y
-7(3)+2y=-19
-21+2y=-19
Add 21 to both sides
2y=2
Divide both sides by 2
y=1
(x,y)=(3,1)
I'm thinking its a im not sure though since i just finished getting out of that unit
