Answer 2

Answer:

Length = 11 1/3 ft; Width = 4 2/3 ft

Step-by-step explanation:

First question:

The length is 2 more than twice the width, so

L = 2W + 2

Second question:

2L + 2W = 32

L = 2W + 2

Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.

2L + 2W = 32

2(2W + 2) + 2W = 32

4W + 4 + 2W = 32

6W = 28

W = 28/6 = 14/3 = 4 2/3

L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3

L = 11 1/3

W = 4 2/3

Answer: Length = 11 1/3 ft; Width = 4 2/3 ft

Tatiana is buying b number of books and m number of magazines at the book fair. The books cost $4 each and the magazines cost $2 each. Tatiana's total purchase can be shown with this expression: 4b + 2m. Which expression is equivalent to 4b + 2m?

Answers

Answer:

2(2b + m)

Step-by-step explanation:

We can simplify the expression given in the question using factoring:

4b + 2m

(2 x 2)b + (2 x 1)m

2(2b + m)

The equivalent expression is 2(2b + m).

What is meant by an expression?

It is a sentence with a minimum of two numbers or variables and at least one math operation.

Given that b is the number of books and m is the number of magazines.

The cost of a book = $4

The cost of a magazine = $2

The given expression for Tatianan's total purchase is 4b + 2m.

The given expression can be simplified as

4b+2m = 2(2b+m)

Hence, 2(2b+m) is the equivalent expression of 4b+2m.

Answers

Answer: 1:2

Step-by-step explanation: you have to subtract 80 from 120 to get 40. Then you would have the ratio 40:80. Then when you simplify it would be 1:2.

The visual work:

120-80=40

40:80=1:2

i know u didnt need the explanation and all that but just wanted to show you how i got it- lol

Answer:

Answer down below!

Step-by-step explanation:

If there were 80 blue marbles, but the amount of red marbles isn't stated. First, you need to figure out how many there are. 80 + Number = 120

Number = 40

The ratio is 80:40

Cutting that in half would be 40:20

We're getting closer

20:10

This is starting to get pretty obvious what our answer could be!

If we kept cutting we would get 2:1

Your answer is 2:1!!

Answers

Answer:

4) Yes

5) Yes

6) Yes

7) No

Step-by-step explanation:

4) When we look at the table in the question, we can see the pattern is comics x 3 = price.

We know the definition of a proportional relationship is when one number is increased, the other is as well. So, it is in a proportional relationship.

5) We do the same thing here, we notice that we can divide the number of bikes by 5 to get the number of trips.

So, this is a proportional relationship.

6) The same reasoning applies to 6, we can see they follow a pattern.

7) All of them can be multiplied by 2, except the last one can't, so this is NOT a proportional relationship.

Given the two points (3, -1) and (5,3), explain how to write the equation of the line in slope intercept form.

*Calculate Slope first

*Calculate y-intercept second

*Write your answer in the form y=mx+b (HINT: you will need to find m and b)

Help quickly!!! I will give brainylist or whatever

Answers

Can you add an image please?

1. To find slope use the slope equation which would be (3 - -1)/ (5-3). The slope is m = 4\2 which is m = 2

2. Plug in one of the points to find the y-intercept. Using the point (5,3) , you would plug this point into the slope intercept equation, along with the slope which was found. 3= (2 x 5) +b. Solving this equation b=-7

3. The slop intercept form is y = 2x - 7

I hope this is the right answer!
