Answer:

<em>Zeina had 35 books and Ali had 5 books</em>

Step-by-step explanation:

<u>Equations</u>

We know Zeina has seven times as many books as Ali. If we call

x = Number of books Ali has

Then Zeina has

7x = Number of books Zeina has

We also know if Zeina gave Ali 15 books, they would have the same number of books, thus:

x + 15 = 7x - 15

Adding 15:

x + 15 +15 = 7x

Subtracting x:

15 +15 = 7x - x

Operating:

30 = 6x

Dividing by 6:

x = 30 / 6

x =5

7x = 35

Thus Zeina had 35 books and Ali had 5 books

docker41 [41]

Answer:

The direction's constant of proportionality is 4. k = 2/0.5 There are 4 gallons of water per one scoop. The student is incorrect because 4 pitchers does not equal 4 scoops times 2 gallons

Step-by-step explanation:

Direction :

1/2 of a scoop + 2 gallons = 1 pitcher

Mrs. Galindo's students:

4 pitcher = 4 scoops + 2 gallons of water

Correct mixture for 4 pitchers:

1/2 scoop + 2 gallons of water =1 pitcher

For 4 pichers, multiply both sides by 4

1/2(4) scoops + 2(4) gallons of water =4 pitchers

4/2 scoops + 8 gallons of water =4 pitchers

2 scoops + 8 gallons of water =4 pitchers

The direction's constant of proportionality is 4. k = 2/0.5 There are 4 gallons of water per one scoop. The student is incorrect because 4 pitchers does not equal 4 scoops times 2 gallons
