Answer:
20
Step-by-step explanation:
Charle would have spent that much because one pound is 2.50
15 divided by 6=2.50
2.50x8=20
X+a=b
you want to isolate x so subtract a from both sides
x=b-a
<span>a whole number; a number that is not a fraction.</span>
The slope of the line that passes through the points (14/5) and (20, -4), so you take y-y/x-x so you substitute the y's in for 5 and -4 and x in for 14 and 20.
5--4/ 14-20
9/-6
Then you make the fraction smaller!
-3/2 = Answer <span />
