You live in a big apartment. The bedroom is 15 by 20 feet. Calculate the area of your bedroom.

Answer:

The answer is B 300 sq. ft.

Step-by-step explanation:

If you multiply 15 by 2 you were to get 30 but since it is 15 multiplied by 20 instead its like adding a 0 at the end of the number so we change 30 to 300.

Hope this helps :)

3(a+b)=19 if a=6, then a+b=?

aniked [119]

Hello!

In a really simple way, 3 times our answer is 19. We can just divide to find it.

19/3= 6 1/3

Anyway, it might be nice to solve the equation for b. If a=6, then b has to be 1/3, but let's check.

18+3b=19

3b=1

b=1/3

Therefore, a+b= 6 1/3

I hope this helps!
