To reach her destination, Jeanette must drive 90 miles. If she drives 5 miles every 7 minutes, how long will it take her to reach her destination? Question 3 options:

2 hours and 10 minutes

2 hours and 2 minutes

2 hours and 6 minutes

2 hours and 12 minutes

2 hours and 15 minutes

2 hours 6 minutes

Step-by-step explanation:

Divide 90 miles by 5 miles

90 ÷ 5 = 18

That is there are 18- 5 mile sections

Each 5 mile section takes 7 minutes , then

18 × 7 = 126 minutes = 2 hours 6 minutes

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
