Answer:
Step-by-step explanation:
2012 = 2500
2500 x .50 = 1250
2500 + 1250
2013 = 3750
3750 x .50 =
3750 + 1875
2014 = 5625
5625 x .50 = 2812.5
5625 + 2812.5
2015= 8437.5
8437.5 x .50 = 4218.75
8437.5 + 4218.75
2016= 12656.25
12656.25 x .50 = 6328.125
12656.25 + 6328.125
2017= 18984.375
18984.375 x .50 = 9492.1875
18984.375 + 9492.1875
2018= 28,476.5625
Answer: x=-17
Step-by-step explanation:
We first distribute the -12 across to the (x+5)
144=-12(x+5)
144=-12x-60
Then, we add 60 to both sides.
204 = -12x
Lastly, we divide the equation by -12.
204/-12 = -12x/-12
-17 = x
You're going to use cross multiplication.
1 gal x 21 miles = 25miles x x
21 miles = 25x
Divide each side by 25 to get x alone
21/25 = 0.84, which is your x value.
