Fred, Norman, and Dave own a total of 128 comic books. If Dave owns 44 of them, what is the average

iren [92.7K]

Answer:

$Mean = 42$

Step-by-step explanation:

Given

Represent Fred with F; Norman with N and Dave with D.

$Total = 128$

$D = 44$

Required

Determine the arithmetic mean of F and N

First, we have that:

$F + N + D = 128$

Substitute 44 for D

$F + N + 44 = 128$

Subtract 44 from both sides

$F + N + 44 - 44 = 128 - 44$

$F + N = 84$

Arithmetic mean of F and N is calculated as follows:

$Mean = \frac{F + N}{2}$

$Mean = \frac{84}{2}$

$Mean = 42$

Lena [83]

Answer:

3x+4 = 5

3x = 5-4

3x = 1

x = 1/3

Since the value of x is found, next step is to substitute it to the x for 6x+7

Value of 6x+7:
