Answer:
The width of the field is 65 feet.
The length of the field is 780 feet.
1 1/4 minutes of 75 seconds
Step-by-step explanation:
10/8 = 5/4 = 1 1/4
5(x-2) - x - 5 = - 3
5x - 10 - x - 5 = -3
4x - 15 = -3
4x = -3 + 15
4x = 12
x = 12/ 4
Therefore x = 3.
f(x) = 7
we use the bottom equation (4x+3) because
1 > 0
so
4(1) +3 = 7
