Answer:

12. 3/4 * 7/8 is < 7/8

13. 4/3 * 3/8 = 1/2

14. 3/5 * 1/6 = 3/10

15. 1/3 * 4/5 < 4/5

Step-by-step explanation:

12. 3/4 * 7/8 is <, >, or =, 7/8

3/4 * 7/8 ? 7/8

21/32 ? 7/8

21/32 ? 28/38

21/32 < 28/32

13. 4/3 * 3/8 is <, >, or =, 1/2

4/3 * 3/8 ? 1/2

12/24 ? 1/2

12/24 ? 12/24

12/24 = 12/24 (1/2)

14. 3/5 * 1/6 is <, >, or =, 1/10

3/5 * 1/6 ? 1/10

3/30 ? 1/10

3/30 ? 3/30

3/30 = 3/30 (1/3)

15. 1/3 * 4/5 is <, >, or =, 4/5

1/3 * 4/5

4/15 ? 4/5

4/15 ? 12/15

4/15 < 12/15 (4/5)

Hope this helps!

Answer for x.<br><br> 1. 3x - 10 = -21<br><br> 2. -22 - 4x = 12
ra1l [238]

Answer:

3x - 10 = -21

add 10 on both side

3x-10+10=-21+10

3x=-11

divide both side by 3

3x/3=-11/3

x=-11/3

Step-by-step explanation:

2. -22 - 4x = 12

add 22 on both side

-22+22-4x=12+22

-4x=36

divide both side by -4

-4x/-4=36/-4

c=-9 is your answer

Sophie practices the piano 105 minutes in 1 week. If t represents the total time she practices for any number of days, d, write
Alex Ar [27]

Answer:

<h3>t = 15d</h3>

Step-by-step explanation:

You must first know that 1 week = 7days

If Sophie practices the piano 105 minutes in 1 week, this can be expressed as;

105 minutes = 7days

to calculate the total time t that she practices for any number of days, d, we will say;

t minutes = d days.

Solving both expression;

105 minutes = 7days

t minutes = d days.

Cross multiply;

7 * t = 105 * d

7t = 105d

Divide both sides by 7;

7t/7 = 105d/7

t = 15d

Hence a proportional equation for t in terms of d that matches the context is expressed as t = 15d

Dash offers and unlimited talk and texting plan for $80 per month AB&amp;C charges $0.20 per text message and $55 for 1,000 min
mr_godi [17]

Answer:

Let's define x as the number of text messages send.

y as the number of 1,000 minutes talk per month.

(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.

> The equation for Dash is:

C1(x, y) = $80

>The equation for AB&C

C2(x,y) = $0,20*x + $55*y

> Horizon

C3(x,y) = $0.10*x + $75*y.

Now, which company you should go for?

Well, it depends on the values of x and y that you have.

if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.

if you usually talk, you may want to go with AB&C because the slope for y is smaller.

If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y
