Answer:
Step-by-step explanation:
Hello!
a)
- 11.5= a
b)
b= -11 -7 = -18
c)
c+3 = 15
c = 15 -3 = 12
d)
-4d = 32
d = -32/4 = -8
Answer: n = 13
Step-by-step explanation:
To find n, you can look at the equation and see that n is being multiplied by 3 to equal 24. Since 8 times 3 equals 24, you can substitute to solve:
8 = n - 5
n = 13
Therefore, through simplification, n is equal to 13.

Answer:
x=-3
Step-by-step explanation:
3(2+x)= -3
Divide each side by 3
3/3 (2+x)= -3/3
2+x = -1
Subtract 2 from each side
2+x-2 = -1-2
x = -3
Answer:
second option -2, -11
Step-by-step explanation:
when you put -2 where x is then
y is -11
assuming you mean 30.5 and 10 feet, the height is 15 feet.
Step-by-step explanation:
Volume = length X width X height
so
4,575 = 30.5 X 10 X height
4,575 = 305 X height
4,575 / 305 = height
15 equals height
