Bob was 5 feet off the ground. He travels 4 feet every single second. How long will it take for him to reach 37 feet?
4x + 5 = 37
4x + 5 (-5) = 37 (-5)
4x = 32
4x/4 = 32/4
x = 8
It will take Bob ~8 seconds to reach 37 feet*
*Problem & answer
hope this helps
Team A: 15 points
Team B: 3 points
Team A has twelve more points than Team B:
A = B + 12
Team A has five times as many points as Team B:
A = B × 5
A = 5B
substitute "A" with "B + 12" to solve for B:
A = 5B
(B + 12) = 5B
B + 12 = 5B
12 = 5B - B
12 = 4B
3 = B
Team B has 3 points
now substitute "B" with 3 to solve for A:
A = 5B
A = 5(3)
A = 15
Team A has 15 points
Check your answer by inputting both values into either equation:
A = 5B
(15) = 5(3)
15 = 15 ✔
A = B + 12
(15) = (3) + 12
15 = 15 ✔
