Answer:
Step-by-step explanation:
Time for first race 57.9seconds
x=time for first half of race
x-4.7=second half of race
Equations is
x + (x-4.7)=57.9
2x-4.7=57.9
2x=57.9+4.7
2x=62.6
x=31.3
Check answer
31.3 + (31.3-4.7)=57.9
31.3 +26.6=57.9
57.9=57.9
A^2 + b^2 = c^2
<span>10^2 + 24^2 = c^2 </span>
<span>100 + 576 = c^2 </span>
<span>676 = c^2 </span>
<span>c = 26</span>
The two truck companies would cost the same amount at 36.36 miles.
<h3>
Linear equation</h3>
Linear equation is in the form:
y = mx + b
where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total cost of rental for each truck for x mile.
From the table, for we-haul:
For you-haul:
For the two trucks to cost the same:
0.45x + 20 = x
x = 36.36
The two truck companies would cost the same amount at 36.36 miles.
