7.6=w/12
w=7.6(12)
w=91.2
x/2=20
x=20(2)
x=40
8.3x=41
x=41(8.3)
x=340.3
54=r/3
r=54(3)
r=162
Ratio is 5girls:7boys with total 72 students
5+7= 12
72➗12= 6
6(5:7)= 30 girls : 42 boys
New ratio is 3:4 with 48 boys
48➗4= 12
So for girls 3x12= 36
So started with 30 girls ended with 36 girls... 6 girls joined band during the school year.
Answer: 576 inches or 48 feet
Step-by-step explanation:
set up a proportion where 
so you get drawingAB = 24 in
actualAB = 18 feet = 18 * 12 in = 216 in
drawing perimeter = 64 in
so plug these in to get
rearrange to get 
and solve to get 576 inches or 576/12 = 48 feet
Answer:
y = 1.5x - 1 or y = 1 1/2x - 1 or y = 3/2x - 1
Step-by-step explanation:
y = mx + b
b is the point on the y
y = -1
so
b = -1
now the slope
m = rise/run
m = 3/2
so
y = 1.5x - 1
