If the average of 3 numbers and 8 is 25 what is the sum of the three numbers

1 answer:

3 0

Let sum of 3 numbers be x.

Average of 3 numbers and 8 = $\frac{x + 8}{4}$

25 = $\frac{x +8}{4}$

100 = x +8

x= 92.

The sum of 3 numbers is 92.

Answer:

The three equivalent options are: $\frac{1}{6}x+47$ , $\frac{5}{3}x+35-\frac{3}{2}x+12$ , and $5(\frac{1}{3} x+(5)(7)-(3)(\frac{1}{2}x)+(3)(4)$

Step-by-step explanation:

Expand $5(\frac{1}{3}x+7)-3(\frac{1}{2}x-4)$ to get $\frac{5}{3}x+35-\frac{3}{2}x+12$ .

Simplifying this gets you $\frac{1}{6}x+47$ .

∠BAD is bisected by . If m∠BAC= 2x - 5 and m∠CAD = 145, the value of x is 150 145 75 70

horsena [70]

We are asked to find the value of x given that ∠BAD is bisected by AC and measurement of BAC is equal to 2x - 5 and measurement of CAD is equal to 145. Since they are bisected, they are equal and the solution is shown below:
m ∠ BAC = m ∠ CAD
2x - 5 = 145 , transpose -5 to the opposite side such as:
2x = 145 + 5 , perform addition of 145 and 5
2x = 150
2x / 2 = 150 / 2 , divide both sides by 2
x = 75

The answer is 75 for the x value.
