Answer:
D. 80 mph
Step-by-step explanation:
d- distance
- d/50= 0.6d/40+0.4d/x
- 1/50= 0.3/20+0.4/x
- 0.4/x= 0.02- 0.015
- x= 0.4/0.005
- x= 80 mph

X=5 pointn
y=7point
x+y=13
5x+7y=71
solve
multiply first equaiton by -5 and add
-5x-5y=-65
5x+7y=71 +
0x+2y=6
2y=6
divide 2
y=3
sub
x+y=13
x+3=13
x=10
10 five point touchdowns
3 seven point touchdowns
