Answer: 4 hours, $160
Step-by-step explanation:
100+15x= 40x
100= 25x
4=x
4 Hours
4*40 = 160
or 100 + 15*4= 160
He had 250 shirts to begin with.
Let x be the number of shirts he began with. He has 10%, or 0.10 of the shirts now he had then. This equals 25:
0.1x = 25
Divide both sides by 0.1:
0.1x/0.1 = 25/0.1
x = 250
Hopes this helps:
Answer: x = 6
Well let's try and find the pair:
(6, 2) (-6, -2)
(7, 1) (-7, -1)
(5,3) (-5, -3)
We can see there are six pairs of such integers. And if you take the sum of each and take the absolute value it is 8. So we do not agree with pat.
