Answer:
5 boys
Step-by-step explanation:
boys to girls in math class = 3/12
3/12 can be reduced to 1/4
In the science class, the ratio is the same but there is a total of 20 girls.
Multiply the fraction 1/4 by 2/2, 3/3, 4/4, 5/5, etc. until you get x/20. Then you have 20 girls. x is the number of boys.
1/4 = 2/8 = 3/12 = 4/16 = 5/20
In science the ratio of 1/4 is the same as 5/20, so there are 5 boys.

❖ Bob ISN'T correct. 5h^2 has an exponent of 2 while 5h only has an exponent of 1. 5h^2 and 5h are completely different due to the exponent.

he know that the angle of each corner is 90º because the two lenghths and the two wides are parallel this means that the figure is a rectangle. so the solution isnumeral A)
Slope for (x₁, y₁) and (x₂, y₂): (1, 6) and (-6, -3)
Slope: (y₂ -y₁) / (x₂ -x₁)
Slope: ( -3 - 6) / (-6 - 1) = -9/-7
<span>Slope = 9/7
