Answer:
16r+8
Step-by-step explanation:
You multiply 4r×4= 16r
Then 4×2=8
That's how you get the answer 16r+8
I would put the equation into two fractions to make a proportion.
30/24 = 20/x
From there, you'd cross multiply to get:
30x = 480
x = 16
So, if there are 20 children currently in the elevator, 16 adults can still enter.
