5*29.95=149.75
20*5= 100 for 500 miles
20/2=10 for 50 miles
Total cost=149.75+100+10
$259.75
You must get x by itself on one side of the equal sign therefore start by subtracting 20 from both sides of the equation the divide .5 from both sides of the equation.
20 + .5x - 20 = 37 -20
.5x = 17
.5x/.5 = 17/.5
x = 34
Plug 7 into each y. 9(7) -4(7) +3
63-28+3
The answer is 38
Answer:
percent decrease
26%
Step-by-step explanation:
Yesterday you ran 5 miles
Today you ran 3.7 miles
The amount went down, so the percent decreased
The percent decrease = (original - new)/original * 100 %
= (5-3.7)/5 * 100%
= 1.3/5 * 100 %
=.26 *100%
= 26%
