To isolate the variable q, divide both sides by 3:
q3 ÷ 3 = 64 ÷ 3
q = 21.33 or 21 1/3
If the q is cubed(I can't really tell), however, you would use the cube root:
³√q³ = ³√64
q = 4
Answer:
3x-10=x+4
Step-by-step explanation:
This might be wrong but probably y= 0.5x ?
Answer:
y = 8x-37
Step-by-step explanation:
y=mx+c
We know the slope m
y=8x+c
We know a point on the line (5,3). Substitute this in for x and y
3 = 8(5) +c
3 = 40+c
3-40 = 40+c-40
-37 =c
y = 8x-37
Let c = cost, s the number of students
Then;
C=50+4.5s
For the 24 students;
C=50+4.5(24)
C=50+108
C=158
