it depends on the grade you make, so if you were to make a 65.47, your grade would be a 70, so any grade less than 70 should be the answer, hope this helps!

Solve the equation. Check your solution. (1/2 is a fraction for one half s-1/2=1/2

Alchen [17]

Answer:

$s = 1$

Step-by-step explanation:

Given

$s - \frac{1}{2} = \frac{1}{2}$

Required

Solve for s

$s - \frac{1}{2} = \frac{1}{2}$

Add $\frac{1}{2}$ to both sides

$s - \frac{1}{2} + \frac{1}{2} = \frac{1}{2} + \frac{1}{2}$

Take LCM

$s + \frac{-1+1}{2} = \frac{1+1}{2}$

$s + \frac{0}{2} = \frac{2}{2}$

$s +0 = 1$

$s = 1$
