Answer: I think it should be 4.5
Step-by-step explanation:
<span>8 + 4s – 2s = 16
simplify
8+2s = 16
subtract 8 to both sides
8 +2s - 8 = 16 - 8
2s = 8
divide both sides by 2
2s/2 = 8/2
s = 4
Answer is C. s = 4</span>
We are given with the equation <span>d + 3n = 1 and asked to solve for n in the problem. the first step is to apply subtraction property by subtracting d to each side of the equation. Hence 3 n = 1 - d. next, we use division property by dividing the whole equation by 3. hence n = (1 - d) / 3</span>
The definition after using if and only if is "<span>an angle is a right angle if and only if it measures 90 degrees".</span>
