Answer: -600 and 1600 were invested into the two accounts.

Step-by-step explanation:

x = amount invested in the first account.

y = amount invested in the second account.

You start off with this equation

x + y = 1000

0.08x + 0.09y=86

Subtract both sides by y.

x=1000-y

Subsitude 1000 - x for x for the second equation.

0.08(1000-y)+0.09y=$86

Use the distributive property to solve for y.

80-0.08y+0.09y=86

80-0.01y=86

6=-0.01y

=-600

Subsitude -600 for y in the first equation and solve for x.

x-600=1000

x=1600

-600 and 1600 were invested into the two accounts.

A soccer league has 160 players. Of those players 40% are boys. How many boys are in the soccer league?
MatroZZZ [7]
The answer is 64 boys are in the soccer league.

X/160 = 40/100

X/160 * 100 = 40/100 * 100

5x/8 = 40

(8 * 5x)/8 = 40 * 8

5x = 320

5x/5 = 320/5

x = 64

broken down: 70 + 20 = 90, 6 + 4 = 10, 90 + 10 = 100 :)
