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.
1. You could write it as a rate.
5 movies = 75 movies
25 TV sitcoms = x sitcoms
2. Cross multiply:
5x = 1875
3. Divide
x = 375 TV sitcoms
you could do the same thing for the second question
5 movies = x
25 sitcoms = 50 sitcoms
cross multiply:
25x = 250
divide:
x = 10
Answer:
50x, x being months.
