Answer:
The answer will just be 125b^4
Step-by-step explanation:
Basically multiply 5 by 5 by 5 and then count all of the b’s (4 b’s) and add it to the product as an exponent
Final answer: 125b^4
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.

simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3
simplify 30/3 to 10
Answer: x = -10

Answer:
81.167~
Step-by-step explanation:
You can find the mean (or average) of a set of numbers by adding them together and dividing the sum by the amount of values there are.
In this case, there are 6 values.
The total sum of the six values is 487.
To receive the mean, divide 487 by 6.
