If you have an average 90. Give two numbers other than 90 that would make the average 90
klemol [59]

Answer:

The numbers 180 and 0 would make the average 90

Step-by-step explanation:

we know that

To find the average of two numbers, add the numbers and then divide by two.

Let

x ----> one number

y ----> the other number

The average is equal to

(x+y)/2

For x=180 and y=0

the average is equal to

(180+0)/2=90

therefore

The numbers 180 and 0 would make the average 90

Given g(x) = 10x + 2, find x when g(x) = 2.
Elan Coil [88]

Answer:

x=0    

Step-by-step explanation:

We are given:

g(x) =10x +2

and

g(x)=2

g(x) is equal to both 10x+2 and 2. Therefore, by substitution, we can set them equal to each other

10x+2=2

Now, we need to solve for x. First, move all the numbers to the same side. Subtract 2 from both sides

10x+2-2=2-2

10x=0

To solve for x, we have to get x by itself. x and 10 are being multiplied. To get x alone, divide both sides by 10.

10x/10=0/10

x=0
