The lcm of 54 and 81 is the smallest positive integer that divides the numbers 54 and 81 without a remainder. Spelled out, it is the least common multiple of 54 and 81
Answer: 7
Step-by-step explanation:
\frac{-14}{-2}
Both 14 and 2 are divisible by 2, so we can divide both of these numbers by 2.
\frac{-7}{-1}
Both numbers are negative, so we can divide both of these numbers by -1.
\frac{7}{1}
This gives us 7.
Looks correct to me but i'm not 100% sure
Multiply each hourly rate by x ( time to complete the work) add it to the service call for each and then set the equations equal:
50 + 40x = 30 +45x
Subtract 30 from both sides:
20 + 40x = 45x
Subtract 40x from both sides:
20 = 5x
Divide both sides by 5
x = 4
The length is 4 hours.
Answer:
N = 10
Step-by-step explanation:
Normally the coordinate system goes:
x axis (horizontal)
y axis (vertical)
Here, we have:
Horizontal axis as "M", and
Vertical axis as "N"
We want to know what N will be when M equals 50.
So, we look at the x-axis and go to M equals 50.
Then we move up until the "trend line". The intersection.
If we move directly left to vertical axis (N variable), we see that it is at the point:
N = 10
So,
When M = 50, N = 10
