Answer:
a = 7 and c = 12
Step-by-step explanation:
Set up 2 equations and use substitution:
4a + 2c = 52
12a + 4c = 132
In the first equation, c = 26 - 2a
We can plug that into the second equation to solve for a.
12a + 4(26 - 2a) = 132
a = 7
Plug a back in to either original equation to solve for c:
4(7) + 2c = 52
c = 12
Flip on to other side and get the points (,)
What do you mean by “rates” ?
If there are 35 drum students out of 112 students, that means there are 77 other band students. So, the ratio of drummers to other musicians would be 35:77, or 5:11 when simplified.
Hope this helps!
