The first car consumed 25 gallons of fuel while the second car consumed 30 gallons of fuel.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the first car consumption and y represent the second car consumption, hence:
x + y = 55 (1)
Also:
15x + 20y = 975 (2)
From both equations:
x = 25, y = 30
The first car consumed 25 gallons of fuel while the second car consumed 30 gallons of fuel.

Answer:
<h3>k = -7</h3>
Step-by-step explanation:
Given the expression
3/5k - 5 = 7/10k
We are to find the value of k
Cross multiply
3(10k) = 7(5k-5)
30k = 25k - 35
30k - 25k = -35
5k = -35
k = -35/5
k = -7
<em>Hence the value of k is -7</em>
