Answer:
French=60,History=120,Music=108
Step-by-step explanation:
I think this is trying to represent the degrees of a pie chart.
To find the degree of the pi chart per person you need to 72/12=6
Than to find the amount of degrees per subject multiply 6*amount of students.
Example:

Multiply 17x5=85,85+5=90 so aswer is 90
Answer:
x = -10
y = -13
Step-by-step explanation:
-6(y + 3) + 4y = 8
-6y - 18 + 4y = 8
-2y - 18 = 8
+ 18 + 18
-2y (÷ -2) = 26 (÷ -2)
y = -13
x = -13 + 3
x = -10
Answer:
Step-by-step explanation:
We need to write this equation in y=mx+b where m is the slope.
3y= -2x +9
y= -2/3 +9
So now that it is in the form of y=mx+b, we can find the slope. -2/3 is the slope of the equation. Hope that helps!
