Answer:
40% of the class are girls
Step-by-step explanation:
9 boys+6 girls=15 students
6 girls/15 students=40%
2(L * W) + 2(L * H) + 2(W * H) = surface area
It would take 64pi ft. sq. or approximately 201.06 ft. sq.
the formula for the surface area of a sphere is 4pi×r sq.
filling in for the radius (r) which is 4
4×pi×4 sq.
4×pi×16
then 16×4=64
therefore being 64 pi ft. sq.
but multiplying the pi would equal approx 201.06 ft. sq.

I believe that 15x is trying tell you to do 15 minus -10 15 times maybe?

X=1
x=2
x=3
2(1)-y=4
2-y=4
-2 both sides
-y=2
÷-1 both sides
y=-2
(1,-2)
2(2)-y=4
4-y=4
-4 both sides
-y=0
y=0
(2,0)
2(3)-y=4
6-y=4
-6 both sides
-y=-2
÷-1 both sides
y=2
(3,2)
