Answer:
it would take him 3.5 minutes
Answer:
x= 16 ft.
Step-by-step explanation:
Let 'x' and 'y' are the lengths of the two pieces then:
1.) x + y = 36
2.) x : y = 4 : 5 cross multiply
3.) 5x = 4y
by solving the system of equations
x + y = 36
5x = 4y
we find
x = 16 ft
y = 20 ft
<span>-2x + 8 + 5x > 2x + 1
3x + 8 > 2x + 1
x > -7
answer
D) - 5</span>
Answer:
Average rate of car: x+3
Walking rate: x
The equation is
10/15 = x/x+3
So
x = 6
So
Average rate of car: 9 mph
Walking rate: 6 mph
