Answer:

Step-by-step explanation:
Number of boys = B
Number of girls = G
Ratio of the number of boys to the number of girls in Ms. Zombo’s class = 



Ratio of the number of boys to the number of girls in Mr. Stolarski’s class = 



Total number of boys in combined class = 21+30 = 51
Total number of girls in combined class = 28+18 = 46
∴ Ratio of the number of boys to girls in the combined classes is 
Answer:
y = - 3x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 2 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes , then
y = - 3x + c ← is the partial equation
To find c substitute (- 1, 3 ) into the partial equation
3 = 3 + c ⇒ c = 3 - 3 = 0
y = - 3x ← equation of parallel line
The answer is D . Because it make them equally to each other which means they are trying to have the same amount
