Answer:
The two angles are 25.5 and 114.5
Step-by-step explanation:
<u><em>x = measure of one angle
</em></u>
<u><em>5x - 13 = measure of the other angle {one angle is 13 less than 5 times the other}
</em></u>
<u><em>
x + 5x - 13 = 140 {sum of the two angles is 140}
</em></u>
<u><em>6x - 13 = 140 {combined like terms}
</em></u>
<u><em>
6x = 153 {added 13 to each side}
</em></u>
<u><em>x = 25.5 {divided each side by 6}
</em></u>
<u><em>5x - 13 = 114.5 {substituted 25.5, in for x, into 5x - 13}</em></u>

Answer:
y=5/2
Step-by-step explanation:
10=4y divide four by both sides to get y by itself 10/4=4y/4 so that equals 10/4=y reduce it so 5/2=y
| b+7 | = 10; you add 2 on both sides.
| b+7 | is always positive
b+7 = 10, b = 10-7= 3.
therefore b = 3
% increases = (66.33 - 48.24) * 100 / 48.24
= 37.5 % answer
