Answer:
x = -4
Step-by-step explanation:
Distribute the -2 into the parentheses and your equation becomes -8x - 8 - 3x - 2 = 34
Then combine the -8x and -3x as well as the -8 and -2 to have -11x - 10 = 34
Add 10 to both sides and get -11x = 44
Divide both sides by -11 for x=-4
The meaning of the question is
Let the unknown number be x
Therefore x+7=16-2x
Now 2x+x=16-7
3x=9
X=9/3
x=3
Answer:
3 inches by 12 inches
Step-by-step explanation:
Length = L
Width = W
LW = 36
L = 36/W
2(L + W) = 30
2(36/W + W) = 30
36/W + W = 15
36 + W² = 15W
W² - 15W + 36 = 0
(W - 3) (W - 12) = 0
W = 3 or W = 12
Therefore the dimension is 3 inches and 12 inches.
using pemdas 2 times 36 is 72 and adding 16 would be 88
