Step-by-step explanation:
Given that M is a positive integer, M + 1 is also a positive integer.
Since the difference between them is only 1, they cannot have a common factor above 1.
(For example if M is even, M + 1 must be odd and therefore they do not have a common factor 2 and so on)
Hence we conclude the GCF of M and M + 1 is 1.
Answer:
27 cubic millimeterse
Step-by-step explanation:
V= lwh
v=3 times 3 times 3
v= 9 times 3
v=27
(sorry if its wrong, its 90% chance im right!)
Hey!

Question #1:
b + 0.6 = -1
b + 0.6 - 0.6 = -1 - 0.6
b = -1.6
Answer:
---------------------------------------------------
Question #2:
y - 0.6 = -1.8
y + (-0.6) + 0.6 = 1.8 + 0.6
y = -1.2
Answer:
---------------------------------------------------
Question #3:
n + 11.5 = -29
n + 11.5 - 11.5 = -29 - 11.5
n = -40.5
Answer:
---------------------------------------------------
Question #4:
e - 14.4 = -20.8
e - 14.4 + 14.4 = -20.8 + 14.4
e = -6.4
Answer:

Let's define variables:
x = Rate in $ / hr of the mechanic working 15hr
y = Rate in $ / hr of the mechanic working 5hr
We have the following system of equations:
x + y = 130
15x + 5y = 1400
Solving the system we have:
x = $ 75 / hr
y = $ 55 / hr
Answer:
the rate charged per hour by mechanics was:
x = $ 75 / hr
y = $ 55 / hr
