Mechanical Advantage = Force by Hammer / Force by Nail = 160/40 = 4
Answer:
6 hours
Step-by-step explanation:
420 ÷ 70 = 6. Divide the distance and speed to get the amount of time.
-86 = -6(-3p - 3) - 5p
Distribute the -6 into the parentheses:
-86 = (-6 * -3p) + (-6 * -3) - 5p
-86 = 18p + 18 - 5p
Simplify:
-86 = 13p + 18
Subtract both sides by 18:
-86 - 18 = 13p + 18 - 18
-104 = 13p
Divide both sides by 13:
= 
= 
<u>p = -8</u>
