Answer:

Hey doing-the-homework-at-the-last-minute-student!

Here's how you gotta do it:-

[tex]\frac{5}{6}[/tex] - [tex]\frac{5}{12}[/tex]

Both the denominators should be same to be subtracted.

So, let's multiply [tex]\frac{5}{6}[/tex] with 2 so that its denominator will be 12 as well.

[tex]\frac{5}{6}[/tex] x [tex]\frac{2}{2}[/tex]

[tex]\frac{10}{12}[/tex]

Now, lets subtract this with [tex]\frac{5}{12}[/tex]

[tex]\frac{10}{12}[/tex] - [tex]\frac{5}{12}[/tex]

While subtracting, you don't have to subtract the denominators. Only find the difference between the numerators- 10 and 5.

10-5 is 5.

So,

[tex]\frac{10}{12}[/tex] - [tex]\frac{5}{12}[/tex] = [tex]\frac{5}{12}[/tex]

[tex]\frac{5}{12}[/tex] is the answer!

I’m not sure what 1. is sorry, but I think I know what 2 and 3 are.
2.) 120/1 x 3/4 because 3/4 is just the fraction form of 75%. Also 120/1 is just 120 as a fraction

Answer:

Length: 10 units.

Width:6 units

Step-by-step explanation:

Part a has 1 unit =40 yards. When we have 1 unit = 20 yards, we have divided the original numbers, 40, in half, getting 20. That means that we need to double the original amount of units, like you see above.

Step-by-step explanation:

a+b=20
1.5a+1.25b=28

what do a and b stand for

Answers

a=20-b (1)
1.5a+1.25b=28 (2)
Sub 1 into 2
1.5(20-b)+1.25b=28
30-1.5b+1.25b=28
-0.25b=28-30
-0.25b=-2
b=-2/-0.25
b=8
—————-
a=20-8
a=12
A= 12 and B= 8
Because 1.5•12= 18 so then take 1.25•8= 10 then add 18+10 which equals 20 when added together

2. 8x + 10

3. 10x + 8

4. -9x + 15

5. -5x + 17

Step-by-step explanation:

In the first problem, you have to do -5x + -8x which is -13x. Then you add 2+9 which is 11. You will get the expression -13x + 11.

In the second problem, you have to do 5x + 3x which is 8x. Then you add 8 + 2 which is 10. You will get the expression 8x + 10.

In the third problem, you have to do 1x + 9x which is 10x. The. you add 4 + 4 which is 8. You will get the expression 10x + 8.

In the fourth problem, you have to do -7x + -2x which is -9x. The. you add 6 + 9 which is 15. You will get the expression -9x + 15.

In the last problem, you have to do -4x -1x which is -5x. The. you add 14 + 3 which is 17. You will get the expression -5x + 17.

Joey has a workout playlist that includes songs from four types of music.
20 country songs
45 rap songs
25 blues
10 R and B
What is a prediction you can make from the type of music Joey will hear when he randomly plays a song from his playlist? (what can we do to try to figure this out?)

A.The song is 3 times as likely to be rap as it is R and B

B.The song is 2 times as likely to be country than it is R and B

C.The song is half as likely to be rap as it is all other songs combined.

Answers

Your answer should be A if not it’s D
I think B would be the correct answer.

County is 20 where R and B is 10, therefore the song would be 2 times as likely t be country than it is R and B.

Marcella bought 12 1/4 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.

How many yards of ribbon does Marcella have left?

6 1/12, you can add 2 1/2 to 3 2/3 to get 6 1/2 then subtract the total yards of ribbon, 12 1/4 by 6 1/6 to get 6 1/12. I believe I’m right.
