Answer:
3 hours
Step-by-step explanation:
1/12 = 1/4 of an hour
1 hour = 4/12
2 hours = 8/12
3 hours = 12/12
Answer:
No
Step-by-step explanation:
No, the decimal part is important.
For example, 1.4≈1, but 1.5≈2
Therefore, Enrique is wrong.
7 + 1.25t = 43.25 <== ur equation
1.25t = 43.25 - 7
1.25t = 36.25
t = 36.25 / 1.25
t = 29 <== he was jumping for 29 minutes
Answer:
x = -7 or x = 2/3
Step-by-step explanation:
I'm assuming you meant solve for x when f(x) = 0.
f(x) = 3x(x + 7) - 2(x + 7)
0 = (x + 7)(3x - 2) -- Both terms have a common factor of (x + 7) so we can group them
x + 7 = 0 or 3x - 2 = 0 -- Use ZPP
x = -7 or x = 2/3 -- Solve
X+4x = 180
5x = 180
x =180/5
x = 36
answer
D. 36
