5 0

Answer:

x = 9

Step-by-step explanation:

Given

2(x + 5) = 3x + 1 ← distribute left side

2x + 10 = 3x + 1 ( subtract 2x from both sides )

10 = x + 1 ( subtract 1 from both sides )

9 = x

By what percent will a fraction decrease if its numerator is increased by 20% and its denominator is increased by 50%?
Brums [2.3K]
Lets find out...

our fraction is 1/2.....
when the numerator is increased by 20%......1 + 0.20(1) = 1.2
when the denominator is increased by 50%....2 + 0.50(2) = 3

1/2 = 0.5....original fraction
1.2 / 3 = 0.4.....increased fraction

 decrease = (original number - new number) / original number...* 100
                 = (0.5 - 0.4) / 0.5...* 100
                 = (0.1 / 0.5)....* 100
                = 0.2 * 100
                = 20% decrease <====
