Answer:

20 miles

Step-by-step explanation:

I'm not sure if that is exactly how you solve it but

If its

8x+4 as the equation and x is the number of hours run

the total number of miles run should be 20 miles

8(2)+4=20

Answer:

20 miles

Step-by-step explanation:

miles already covered = 4

rate of speed = 8miles / hour

miles to be covered = 8 miles/hr× 2 hr= 16 miles ( because distance is velocity × time)

total miles covered = 16 + 4 = 20 miles.

To edit a manuscript, Miguel charges 12 dollars per hour for the first 4 hours and 15 dollars per hour after the first 4 hours.
aleksley [76]

Answer:

C = 12 + 15(x - 4)

C = 15x - 48

Step-by-step explanation:

Let the number of hours = t

The total amount Miguel earns =

C

To edit a manuscript, Miguel charges 12 dollars per hour for the first 4 hours and 15 dollars per hour after the first 4 hours.

C = 12 + 15(x - 4)

Expand the t

C = 12 + 15x - 60

C = 15x - 48

Therefore, an expression for the amount, in dollars, Miguel charges if it takes him t hours to edit a manuscript, where t>4 is given as:

C = 15x - 48

Naddika [18.5K]

Answer:

field goal points: 213

extra points: 125

Step-by-step explanation:

Given that a field goal is worth 3 points, then the total points made by field goals are: number of field goals * 3. In the case of Adam, that is: 71*3 = 213 points.

An extra point is worth 1 point, then 125 extra points are equivalent to 125 points.
