P = 2(L + W)
P = 112
L = 35
112 = 2(35 + W)
112 = 70 + 2W
112 - 70 = 2W
42 = 2W
42/2 = W
21 = W <=== width is 21 inches

3x=2x+14
-2x -2x
x=14
A = pi x r^2
A = pi x 8^2
A = pi x 64
A = 201.061..
A = 201cm^2 (3sf)
Answer:mr.Sinofsky used 2 tanks of gas altogether
Step-by-step explanation:
Mr.Sinofsky used 5/8 of a tank of gas on a trip to visit relatives for the weekend.
He used another 1 half of a tank commuting to work the next week. Converting 1 1/2 tank of gas to improper fraction, it becomes 3/2 tanks of gas.
He then took another weekend trip and use 1/4 tank of gas. Therefore, the total number of tanks of gas that Mr.Sinofsky used would be
5/8 + 3/2 + 1/4 = (5 + 12 + 2)/8 = 19/8
= 2 tanks of gas
