Otrada [13]3 years ago
4 0

Answer:

It's the second option x = (3y - 11) / 5.

Step-by-step explanation:

3/5 = x+1/y-2

Cross multiplying:

3(y - 2) = 5(x + 1)

3y - 6 = 5x + 5

5x =  3y - 6 - 5

5x = 3y - 11

x = (3y - 11) / 5.

Your dog is 8 years younger than your friend. In 2 years, your friend will be three times as old as your dog. How old is your do
ra1l [238]

Answer:

Dog is 2 years old

Step-by-step explanation:

Let dog's age = d

Let friend's age = f

Your dog is 8 years younger than your friend:

d +8 = f

In 2 years, your friend will be three times as old as your dog:

3(d+2) = (f+2)

3d+6 = f+2

3d = f - 4

(sub in f=d+8 from above)

3d = f - 4

3d = d+8 - 4

2d = 4

d = 2

6:18 students in Debra's class own a cellphone. Because there are 24 people in total. Minus the people who already own cellphones. Leaving 18 without cellphones. The ratio is people who have cellphones to people who do not. 
24-6=18. Thus, the ratio would be 6:18

It cost Hudson $28.20 to send 188 text messages. How much would it cost to send 63 text messages? Good luck!
frosja888 [35]

Answer:

$9.45

Step-by-step explanation:

1.  First, you want to figure out how much one text message costs.  To do this, divide the dollar amount (28.20) by the number of text messages (188).  You get 0.15, or $0.15 per text message.

2. Using this $0.15 per text message, you can calculate how much 63 text messages costs.  You simply multiply $0.15 by 63 to get $9.45, which is your answer.

Hope this helps! :)
