Russell has been training for the Emerald Valley Race. The first week he trained, he ran 5 days and took the same two routes each day. He ran 2 miles around the football field before school and ran a longer route through his neighborhood after school. By the end of the week, Russell had run a total of 30 miles. Which equation can Russell use to find how many miles, x, he ran each day after school?

x=4

Step-by-step explanation:

5day, 2m before school, total 10m before school

5x after school

10+5x=30

5x=30-10

5x=20

x=4

the equation would be something like 30=5x+10

Step-by-step explanation:we know the total is 30 miles

he ran 5 days

the morning run is 2 miles

2*5=10

10 plus the unknown miles times 5 days gives us 30

so 30=5x+10 subtract 10 both sides

20= 5x=20

divide both sides by 5

x=4

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
