Answer:
13.5
Step-by-step explanation:
7 1/2=7.5
7.5/5*9=13.5
Answer:
Step-by-step explanation:
(-1 -7)/(-5 + 5) = -8/0 = undefined
-2 ≥ u - 11 > -3
Add 11 to both sides:
9 ≥ u > 8
Answer: 9 ≥ u > 8
Answer: n=15
Step-by-step explanation:
To find the perimeter, you add all of the side lengths together. This would make the equation 28+28+n+n. You already know the perimeter and are trying to find n. Your new equation is 28+28+n+n=86
You would then combine the like terms and get
56+2n=86
Then you would subtract 56 from both sides and get
2n=30
Finally, you want to divide both sides by 2 in order to get n alone. 30/2 is 15. Therefore,
N=15
