Step-by-step explanation:
We can us rule of three to solve this problem.
We have that 3 laps are done in 8 minutes, and we want to know how much time it will take to run 10 laps:
laps minutes
3 ----------->8
10----------->
To find the value of x we do as follows:
minutes
we cross multiply the values, and divide by the remaining value, thus we have the time it takes to run 10 laps is 26.27 minutes

Answer:
<h2>d = 8</h2><h2>g = 2</h2>Step-by-step explanation:
8d + 4 = 5d + 28
Group like terms
That's
8d - 5d = 28 - 4
3d = 24
Divide both sides by 3
d = 8
Cross multiply
we have
7(7g + 8) = 38.5(4)
49g + 56 = 154
49g = 154 - 56
49g = 98
Divide both sides by 49
g = 2
