PLEASE HELP ME QUICKLY Last week, Shiloh owed her brother $25.50. This week, she owes him another $6.30, for a total of $31.80.

The story above can be modeled by the addition problem -25.50 + (-6.30) = -31.80. Write a related story that is modeled by the division problem -31.80 ÷ 6 = -5.30.

Carla has 6 brothers and she owes all of them equal amounts of money. In total she owes all of them $31.80 which means that she owes all of them 5.30 each

Step-by-step explanation:

she owes each friend $5.30.

Step-by-step explanation:

Sarah had $31.80 and she owed 6 friends money.

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.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
