Answer: The Answer is 27

Step-by-step explanation:

3/5 means "divide by 5 and multiply by 3"

or "multiply by 3 and divide by 5", it comes to the same thing. But in this case is more difficult to do.

So:

45/5 = 9;

9 x 3 = 27

Or:

45 x 3 = 135

135/5 = 27

11. Jimmy bought some used video games and used movies at the Movie Barn. He bought a total of 15 items and spent $106 in all, n

jolli1 [7]

Answer:

Used Video game = x = 11

Used movie = y = 4

Step-by-step explanation:

Let

Used Video game = x

Used movie = y

x + y = 15 (1)

10x + 6y = 106 (2)

From 1

x = 15 - y

Substitute x = 15 - y into (2)

10x + 6y = 106

10(15 - y) + 6y = 106

150 - 10y + 6y = 106

-10y + 6y = 106 - 150

- 4y = -44

Divide both sides by -4

y = -44/-4

= 11

y = 11

Substitute y = 11 into (1)

x + y = 15

x + 11 = 15

x = 15 - 11

= 4

x = 4

Used Video game = x = 11

Used movie = y = 4

First You do 30.75 x 12 This is because he said every month for a year and a year has 12 months The answer to 30.75 x 12 is 369 Now all you have to do is 550 - 369 = 181.

Hope this helps :D

EleoNora [17]

Answer: Add the number previously added multiplied by 3;

+3x, where x is the number that was added previously

Step-by-step explanation:

3+5=8. That's the first equation, where 5 is x. Then the next equation, 8+3x=23. 8+15=23. It works for all of the equations, so that's the pattern.

Adam uses coconut milk for the dessert.

Ivanshal [37]

So basically, since you know the equation and all of the dimensions, just plug in all of the numbers.

V = $\pi$ r^2 h
V = 3 [the radius is diameter / 2] 4^2 * 12
V = 3 * 16 * 12
V = 48 * 12
V = 576

So there is 576 cm cubed of milk inside of the can.

(Whether it's filled to the brim, probably not.)

I hope I helped! :)
