Answer:
He made 7 3-point shots.
Step-by-step explanation:
x+y=19
2x+3y=45
y=19-x
2x+3*(19-x)=45
2x+57-3x=45
-x=45-57
-x=-12
x=12
y=19-12
y =7
Answer:
123.5 m^2
Step-by-step explanation:
The area of the whole rectangle is 9 x 19 = 171 m^2
The area of the region that isn't shaded is (5 x 19)/2 = 47.5 m^2 because the height of the triangle is 5 (9 - 4) and the area of a triangle is
(height x length)/2
171 - 47.5 = 123.5 m^2
