Answer:
On 3 gallons, he could travel 75 miles
Step-by-step explanation:
50 / 2 = 25 miles per gallon
25 * 3 = 75miles
Unknown side = (25^2-5^2)^.5 = 24.5
Using the Pythagorean theorem
Probably C. 30 Hope this helps I might wrong sometimes
Multiply both sides by 10 to clear the fractions.
2[10-5(x-2)]=x+1
distribute the 2 on the left hand side
20-10(x-2)=x+1
distribute the 10
20-10x-20=x+1
cancel out the 20
-10x=x+1
collect like terms
-11x=1
divide both sides by -11 to solve for x
x=-1/11
