Answer:
20 miles per gallon
Step-by-step explanation:
We want a unit rate where
1 is in the denominator
so we divide top and bottom by 20
= = 20 miles a gallon
7. 11
8. 21.5
9. 9
10. 35-12 =x and x = 13
11. 8 and 9
Your equation should be 1.50x + 13 = 35.50
first, subtract 13 from both side leaving you with 1.50x = 22.50
now divide 1.50 from both sides
x = 15 (greatest number of rides)
1 5/6 divided by 5 2/5
1) Turn the mixed numbers to improper fractions: 1 5/6= 11/6 and 5 2/5= 27/5
New Equation: 11/6 divided by 27/5
2) Keep the first fraction, change division to multiplication, and do the reciprocal of the second fraction
New Equation: 11/6*5/27
3) Multiply numerator with numerator and denominator with denominator
New Fraction: 55/162
Since you can't simplify 55/162 any further, that will be your final answer.
