2(5x)2(-7)=2x+10
2(5x)= 10x
2(-7)=-14
10x-14=2x+10
Solve:
10x-2x=8x
8x-14=10
14+10=24
8x=24
24/8=3
X=3
Let x be the number of rolls of wallpaper that you can buy to decorate your kitchen. Since each roll costs $10, the total cost for x rolls is 10x. This value should be not be more than $50. The inequality that is best described is
10x ≤ 50
Solving for x gives an answer of x ≤ 5.
I can't see the figure entirely. To solve for the perimeter you need to know the height!
Answer:
17/12 = 1 5/12
Step-by-step explanation:
The common denominator of 4 and 3 is 12.
The equivalent fraction of 3/4 is 9/12.
The equivalent fraction of 2/3 is 8/12.
Their total is 17/12 (or 1 5/12).
The answer is m= -13
because 32-45=-13
