Answer:
<em>The number of students in the drama club is 7 and the number in the choir is 14</em>
Step-by-step explanation:
X = Number of students in choir club
Y = Number of students in drama club
<u>First equation:</u>
x + y = 21
<u></u>
<u>Since we know that there are 7 more students in the choir club than the drama club, that means:</u>
x + 7 = y
<u>A little trick that you can do to find y is this:</u>
21 students in the choir and drama club - 7
=> 14
Meaning that y is 14
<u>So lets go back into our second equation:</u>
x + 7 = 14
7 + 7 =14
x=7
<u>Plug both variables in:</u>
7 + 14 = 21
So that means that there are 7 students in the drama club and 14 students in the choir club.
Answer:
they all equal 22 and then add the varible next to it

Step-by-step explanation:
3/2x - 3 = y
using y = mx + b, where m is slope and b is the y intercept, we can eliminate the top two answers by finding the y intercept at -3.
You can find the slope of the graph by using any given point and then calculating rise over run. In this case, the rise is 1.5, and the run is 1, which equates to 3/2
b = -3
m = 3/2
Your answer is highly correct
