I’m pretty sure the answer is 3 because the z stands for a missing number so 2+3=5

Simplify both sides of the equation.

2+-z=5

-z+2=5

Subtract 2 from both sides.

-z+2-2=5-2

-z=3

Divide both sides by -1

-z = 3

-1 = -1

z=-3

68.5. You take 62 and divide it by the percentage as a decimal, .905. 62 / .905 = 68.5.

Step-by-step explanation:

-Paul is 6ft, and has a 10ft shadow. The pole has a 85ft shadow:

-Using ratios:

$\frac{Height\ of \ object}{Height\ of \ shadow}$

Let h be the height of the flagpole:

$=>\frac{6}{10}=\frac{h}{85}\\\\h=\frac{6\times 85}{10}\\\\h=51$
