Jalen and Monique will usually both run 7.5 miles each time they go running. This month, Jalen ran an additional 32 miles. Which answer choice shows an expression that represents the total distance Jalen and Monique ran this month if j = the number of times that Jalen ran and m = the number of times that Monique ran? 1 .15j + 15m
2. 15jm
3. 7.5j + 7.5m + 32
4. 7.5jm + 32

Option 3.

Step-by-step explanation:

It is given that Jalen and Monique will usually both run 7.5 miles each time they go running.

Let,

j = the number of times that Jalen ran.

m = the number of times that Monique ran.

So,  according to this

Distance covered by Jalen in this month = 7.5j

Total distance covered by Monique in this month = 7.5m

It is given that this month, Jalen ran an additional 32 miles.  

Total distance covered by Jalen in this month = 7.5j +32

The total distance Jalen and Monique ran this month is

Therefore, the correct option is 3.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

step-by-step explanation:

mean or average is 40.6
