Answer:

y = -x -3x +y = -3

Step-by-step explanation:

Rearrange as required.

The slope-intercept form is ...

Eliminating parentheses and solving adding 4 gives ...

  y -4 = -x -7

  y = -x -3 . . . . . . slope-intercept form

The ratio of men to women in the astronomy club is 3 to 2. The club has
60 members. How many club members are women?

Answers

Plus the two parts if the ratio 3+2 so 5
Divide the 60 members by 5 and get 12
12 is one part of the ratio
12x2 is 24 so 24 woman
24

Because you divide 5 by 60 to find out how much 1 is equal too which is twelve so 1=12 and because there is two for women it’s 12+12 which is 24

High-definition televisions have an aspect ratio of 16: 9. The following answer choices are television screen sizes rounded to the nearest inch. Which could be a High-definition television?

Answers

Answer:

18.5 in approx

Step-by-step explanation:

Given data

aspect ratio of 16: 9

L= 16in

W= 9 in

We want to find the diagonal of the TV

applying Pythagoras theorem

d^2= l^2+w^2

d^2= 16^2+ 9^2

d^2=256+81

d^2= 337

d= √337

d= 18.35 in

Hence the tv is 18.5 in approx

Mrs. Curry own a hair salon. One day, she gave 12 haircuts. She eamed $19.95 for each and received an average tip of $2 for each

d. 12(19.95 +2)

Answers

Answer:

Option d     12(19.95 + 2)

Step-by-step explanation:

The answer would be an option d, since we know that she gets paid $19.95 plus the $2 per haircut, and we know that she gave 12 haircuts there for we multiply the sum of $19.95 and $2 by 12, and that can be written down as...

12(19.95 + 2)

Judy studied for 7/12 hours and her sister studied for 2/3 of a hour about how much time did they studied all together

Answers

So you first need to make both equivalent fractions. You do that by making the denominator the same so you need to find a common multiple between both which is 12 so you multiply 2/3 by 4 on the top and bottom to get something equivalent to 7/12. 7/12 +8/12=15/12 now you divide 15 and 12 to have it in fraction mode you’ll be getting that Judy and her sister studied for 1 hour and 25 minutes

The required time they all together spend time on the study is  1 1/4 hours.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Judy studied for 7/12 hours and her sister studied for 2/3 of an hour
Total time spend on study all together = 7 / 12 + 2 / 3
                                                           =  1 1/4 = 1.25 hour

Thus, the required time they all together spend time on the study is  1 1/4 hours.

2/5 x 5/4 in fraction in its simplest form​

Answers

Answer:

The answer is 1/2. When you multiply the numerator and denominator, you get 10/20. If you divide the top and bottom by 5, you get 1/2.

The equivalent value of the fraction is A = 1/2 = 0.5

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = pq

when the value of p = 2/5

And , when the value of q = 5/4

On simplifying the equation , we get

A = ( 2/5 ) ( 5/4 )

So , the left hand side of the equation is equated to the right hand side by the value of ( 2/5 ) ( 5/4 )

A = ( 2/5 ) ( 5/4 )

A = ( 2 x 5 ) / ( 5 x 4 )

On simplifying , we get

A = 10/20

Divide by 10 on the numerator and denominator of the fraction , we get

A = 1/2

A = 0.5

Therefore , the value of A = 1/2 = 0.5

Hence , the fraction is A = 1/2 = 0.5

If a student saves $35 per week how long will it take to save enough money to buy a computer

Answers

Answer:

How much does the computer cost?

Step-by-step explanation:

When you let me know I'll come back and help you with the answer :)

Tt will take  [tex]$\frac{x}{35}[/tex] weeks to buy the computer

We have student who saves $35 per week.

We have to determine how many weeks will it take to save enough money to buy a computer.

If you save $30 per week, how much money you will save in 10 weeks ?

In 10 weeks you will save - 30 x 10 = $300

According to the question, we have -

Amount saved per week -  $35

Assume that the cost of the computer is $x.

Now -

$35 → 1 week

$1 →  [tex]$\frac{1}{35}[/tex] week

$x →  [tex]$\frac{x}{35}[/tex] weeks.

Hence, it will take  [tex]$\frac{x}{35}[/tex] weeks to buy the computer. You can put the cost of computer at the place of x and determine the number of weeks needed.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows:

12(5+2y)=4y-(5-9y)
