Answer:
50x2 =100
So the final box is 50x2 = 100
Step-by-step explanation:
There is a pattern in this table. 5, 2, and 2. Ex. 2x5=10, 10x2 =20 on top
The pattern is the same on the bottom: 5x5 =25, 25x2=50, and 50x2 =100
So the final box is 50x2 = 100
Set up a proportion. 2/5 = x/40 to solve the equation first cross multiply. x*5=40*2 x*5=80 now divide both sides by 5, 80 divided by 5 is equal to 16. so the number of girls in the computer lab is 16.
