7 1/2 * 2 = 15
The 3rd hour was 1/4 of the total distance in 3 hours.
1/4 = 0.25 as a decimal, and 25% as a percent.
15 (0.25) = 3.75
15 + 3.75 = 18.75
0.75 = 3/4 as a fraction.
So, he cycled 18 3/4 miles in 3 hours.
I hope this helps, and I am sorry if I get this question wrong. (which is in all likelihood)
Step-by-step explanation:
you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.
if yes, it was a solution, and if just only one is false, then it was not a solution.
(3, -2) in
y + 4x = 10
5x - y = 13
so,
-2 + 4×3 = 10
-2 + 12 = 10
10 = 10 true
5×3 - (-2) = 13
15 + 2 = 13
17 = 13 false
so, it was NOT a solution.
Answer:
4.4
Step-by-step explanation:
16.8 was for 4 hour
divide 4 by 16.8
you get 4.2 per hour
so you need 1 hour
1 hour would be 4.2
temp would be -4.2 at 9pm
