Solve the equation 0.25 (8z - 4) = z + 8 - 2z
Andrew [12]
Distribute

add like terms
2z-1=-z+8
add z to both sides
3z-1=8
add 1 to both sides
3z=9
divide both sides by 3
z=3

Dafna1 [17]
The probability that none of the shoes are black is 51.2%.

If 20% of the shoes are black, then 80% of the shoes are not black. To find the probability that three shoes are not black, we have to multiply 80% by itself 3 times.

0.8 x 0.8 x 0.8 = 0.512 = 51.2%
