I'm assuming your answers are listed as 1 through 4, not decimals.
You simply take 12 - 8 = 4, but ten min. less than that, so 3 hr, 50 min. then add 3 hr 45 min, totaling 7 hr 35 min. , which is closest to 7 and 1/2 hours, the second option.
B( use your hourly wage and tips)
Answer:
16+c
Step-by-step explanation:
Sum means we will have to add. When it says "sum of sixteen and c" it is telling us to add both sixteen and c together.
60% of trip = 45 miles
let total trip distance = l
60% is given by multiplying by 0.6
So;
0.6l = 45 \\ \\ l = \frac{45}{0.6} \\ \\ \boxed{l = 75}
Your answer is 75 miles
9x^2 - 8x - 1 = 0
(9x + 1(x - 1) = 0
x = -1/9 , 1
x intercepts are -1/9 and 1.
