.33 repeating is the answer
If I’m not mistaken then the answer would be 6 because if it burns 2 gallons of gas per hour multiply that by 3 and it becomes 6
Answer:
10
Step-by-step explanation:
3^2*2-4(3-1)
3^2=9
9*2
9×2
18
4(3-1)
4(2)
8
18-8
=10
So the final answer is 10
9514 1404 393
Answer:
c) x = 6
d) x = 2
Step-by-step explanation:
In general, you want to "undo" what is done to the variable.
When variable terms are on both sides of the equal sign, you want to collect them on one side of the equal sign first. I like to do that by adding the opposite of the variable term with the lowest (most negative) coefficient.
<em>Whatever you do to one side of the equation must also be done to the other side</em>.

c) 2(x +3) = 18
x +3 = 9 . . . . . . divide both sides by 2
x = 6 . . . . . . . . . subtract 3 from both sides
__
d) 2x +15 = 27 -4x
6x +15 = 27 . . . . . . . add 4x to both sides
6x = 12 . . . . . . . . . . . subtract 15 from both sides
x = 2 . . . . . . . . . . . . . divide both sides by 2
