where is the question?????????
Answer:
Oh easy...
Step-by-step explanation:
Multiply the numerator on the left by the denominator on the right, and the numerator on the right by the denominator on the left, to solve a proportion. Cross multiplying is the term for this. Simplify the equation, then solve for the variable using the inverse operation, division.
Answer:
590 miles
Step-by-step explanation:
let's set it up
200=base
0.15 is our variable
and total is 288.50
200+0.15x=288.5
subtract 200 from both sides
0.15x=88.5
divide 0.15 from both sides
x=590
we can plug it in to double check our work
200+0.15(590)=288.50
Just do 9 divided by 15, and it equals 0.6.
Or an equivalent fraction would be 18/30, and that is found by multiplying the numerator and denominator by an equal factor of 2.
