11x + 6 = 28

Answers

Answer:

X = 2

Step-by-step explanation:

11 x 2 = 22

22 + 6 = 28

Answer is 2
Explanation: you first try to isolate the x
And your only choice is to subtract the 6 so it cancels out on that side and whatever you do to one side you always have to do to another so 28-6 equal 22, 11x=22, now you divide by 11 making it x = 2. Hope this helps if you have any questions ask me

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

5. "Rewrite the equation from question 4 by factoring the side that contains the varible p."

6. "Solve the equation for p to find Paula's age. Express her age in years as a fraction."

7. "How many months old is Paula?"

Answers

Answer:

Answer:

Raul's age is 15 years.

Step-by-step explanation:

r represents Raul's age.

The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age.

The first presidential election happened 39 years after the Great Depression and six years less than three times Raul's age is 3r - 6.

Therefore, 3r - 6 = 39

Add 6 to both sides.

3r = 45

Divide both sides by 3.

r = 15

Hence, Raul's age is 15 years.

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!!

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.
