Charlie won the marathon running 26.1 miles in 3 hrs and 18 mins. What was his average speed miles per hour

1.45

Step-by-step explanation: The question is asking "what was his average speed per miles per hour" and it says "26.1 miles in 3hrs and 18mins". So it wants to know the speed per hour.

Your gonna take 26.1 and divide it by the 18mins, which will give you 1.45

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3

=

−37

−3

x=

the correct answers i think are b. and d.

give me brainliest if it is correct!
