Answer:
x = 5
Step-by-step explanation:
-2 -1(coeffcient of -x) = -3
-3x +3 =-12
subtract 3 (the constant) from both sides
cancelling it on the left and leaving -3x = -15
divide each side by -3 leaving x and 5
x = 5
Well Wouldn’t that be 6? Because you asked 3 people to do a favor then you,ask each of them to do a favor for 3 more people easy 3+3=6.Hope this helps!
The volume of the rectangular prism is

Where:
L is its length
W is its width
H is its height
From the given figure
L = 15.2 cm
W = 8 cm
H = 5.8 cm
Substitute them in the rule above

Round it to the nearest tenth

Answer D
Your answer will be a repeating decimal or fraction
54.333
54 1/3
Substitute -2 in for x and get (9)^-2
Flip the equation so that the exponent is positive and get 1/9^2
Work it out 1/(9*9) = 1/81
