x= -33/2 or x=-16.5
Step-by-step explanation:
Expand the bracket
6(2x+3) = 2(5x-3)
12x+18=10x-15
Bring like terms together
12x-10x=-15-18
2x=-33
x=-33/2
Answer:
9.9 gallons
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (250, 275, 9) as shown below:

Next we cross multiply. We multiply 250 and x, and we multiply 9 and 275.


Now, lets put the values above back into the equation:

Lets solve this equation. First we divide 2,475 by 250, making x by itself.


This means that to drive 275 miles, Kala would need to use 9.9 gallons of gas.
