<u>Answer:</u>
9c + 10 (see below)
<u>Step-by-step explanation:</u>
To find how much Chris spent on tickets, you can write an expression to represent the situation:
$9c
You can do this to find how much Michael spent as well:
$10m
To find how much Chris and Michael spent combined, add their two costs:
9c + 10
X= weight of TV
y= weight of CD
3x+5y= 62.5
3x+ 2y= 52
You can either solve for a variable, or eliminate a variable by subtracting the second equation from the first:
3x + 5y = 62.5
-(3x+2y = 52)
0 + 3y = 10.5, so y = 10.5/3 or 3.5.
Now plug y= 3.5 back into any equation to get x:
3x + 5(3.5) = 62.5
3x + 17.5 = 62.5
3x = 45
x = 15
Always check work. Both equations should be true for x=15, y= 3.5
Add 25 to both sides x-25 +25 =7 +25
x =32
Answer:

Exact Form: 4.2°
Decimal Form: 4.2
I hope this helps!
Pretty sure it would be 22.
17+7^2=66
17-2(7)=3 and you would divide 66 by 3
