Raul took 2 hours and 30 mins to bike 31 1/4 miles. Well 31 1/4 is equivalent to 31.25 and 2hr 30mins is equivalent to 2.5. Now we need to divide the distance by the time to get the rate in mph. 31.25/2.5 = 12.5 So Raul rode at 12.5 miles per hour.
625 i think but im just multiplying by 2.5
For this case we must divide the following expression:
And in this way we get the amount of money that each person will receive.
Then applying double C we have:
Thus, each person has 0.133x of money!
Answer:
0.133x
Answer:
-4 <u>+</u> 2*sqrt(5)
Step-by-step explanation:
2x^2+16x-8=0
Factor out the 2: 2(x^2+8x)-8=0
Add (b/2)^2 = (8/2)^2 = 16
2(x^2+8x+16)-8 = 0 + 2*16
2(x+4)^2=40
(x+4)^2=20
x+4=<u>+</u>sqrt(20)
x=-4<u>+</u>sqrt(20) = -4 <u>+</u> 2*sqrt(5)
n x m + r = t
number of miles times cost per mile plus fixed rate equals total
