Answer:

c=7

Step-by-step explanation:

The problem says that 8 less than 4 times c is less than twenty, so we can first show 8 less than 20.

4c -( I did this because it said 4 times the number c)

Then, we show 8 less than that.

4c-8

It says it is twenty, and that means it equals twenty.

4c-8=20

Now we solve!

4c-8=20

   +8  +8

*we add 8 to both sides*

4c=28

*we divide both sides by 4 since we want to isolate c*

c=28/4

c=7

I hope this helped!

Answer:

-5

Step-by-step explanation:

because 8 less than 4

= 4 - 8

= -4

and if -4 x c = 20 then...

c= 20÷ - 4

= -5

so c= -5
