You need to find an area of one rectangular wooden plank 8*3,
and then top and the bottom area is 2*8*3
and total area is 12*2*8*3
Answer:
12
Step-by-step explanation:
do the math
69 is the answer the equation would go as: 2(3.14)(11)=69.08
1/5 of an hour is 12 minutes. 60 seconds x 12 minutes= 720 seconds
1. 13.75= 0.25b +0.50
-0.50 -0.50
13.25 = 0.25b; divide both sides by 0.25 to isolate b and you get:
53 = b
2. 10w + 4w = -84
Add like terms!
14w = -84; divide both sides by 14 to isolate w and you get:
w = -6
