Answer:

The value of x is 221 when  k = 17 and  y = 13.

Therefore the Option (C) is correct .

Step-by-step explanation:

As given

x varies directly as y.

x\propto y

x = ky

Where k is the constant of proportionality.

As given

x = 153 when y = 9

Put in the above

153 = 9k

k = \frac{153}{9}

k = 17

Now Find out the value of x when k = 17 and  y = 13.

x = ky

x = 17 × 13

x = 221

The value of x is 221 when  k = 17 and  y = 13.

Therefore the Option (C) is correct .

Answer this question I will Mark brilliant and gets 70 PTS <br>do number one or two or do both ​
yanalaym [24]

Answers And Explanations:

Question 1.

Pulling out like terms :

1.1     Pull out like factors :

  12y - 10  =   2 • (6y - 5)  

Equation at the end of step  1  :

  Divide both sides by  2  

 

 Divide both sides by  6  

 y-(5/6)  > 0

Add  5/6  to both sides

y > 5/6.

Therefore, y = 5/6

__________________________________

Question 2.

To make fractions improper with whole numbers, you must <u>multiply the Denominator by the whole number, then add the Numerator to the Product.</u>

<u></u>

First we multiply 32 by 5.

32 x 5 = 160.

Then we add the Numerator which is 1.

160 + 1 = 161, then we put it over the Denominator, your final answer is 161/5.

Therefore, 161/5 is your final answer.

Have any questions? Feel free to comment below!

Thank you and Best of Luck to you!

Write a fraction that is less than 5/6 and has a denominator of 8
KatRina [158]
You'll want to make a common denominator with 6 and 8.
That denominator would be 24.
24/6=4 so you would have to multiply 5/6 by 4/4 to get 20/24.
Next, 24/8=3 so 1/8 could be multiplied by 3/3 to get 3/24.
Since 3 is less than 20, 1/8 is smaller than 5/6.

If you want the same numerator, 5/8 = 15/24. This would make 5/8 smaller than 5/6 as well.
The highest eighth you can go is 6/8 which is 18/24.
So you can use any numerator between 1 and 6 with a denominator of 8 to get a fraction smaller than 5/6.
