Which two expressions are equivalent?

A. 7(3 + x) and 7∙ 3 + 3 ∙ x
B. 7 + 3 + x and (7 + 3) + x
C. 7 ∙ x ∙ 3 and 7(x + 3)
D. 7 ÷ (3 – x) and 7 ÷ (x – 3)

Answers

Answer 1
B

explanation: the commutative property shows that equations like (7+3)+x, 7+(3+x), and 7+3+x are all equivalent
Answer 2
Your answer is B because the first on you are adding from left to right and in the second one, you are just adding parentheses around something that was going to get added together anyways and overall, they both come out to 10+x

Answer:

Your answer will be the third one.

Step-by-step explanation:

If you add up the numbers on top for the first, secnd, and fourth ones and divide that by the number ont he bottom, you will constantly get 6. However, for the third one, you'll get seven since 9+9 is 18 and 5+5 is 10. Add that up and you get 28, and divide that by 4 and you get 7, not 6. hope this helps!

Answer: (9+9+5+5)/4

Step-by-step explanation:

Because if you add all of the numbers on the numerator and divide by the denominator, all of them equal 6 except that one. So it doesn't belong

Find the measurement of one of the vertical angles .

Answers

Answer:

x = 15 degrees, one vertical angle is 165 degrees

Step-by-step explanation:

3x = x + 30

3x - x = 30

x(3-1) = 30

2x=30

x=15

All the angles need to add up to 360 degrees.

15 + 15 + 2y = 360

2y = 330

y=165

Answers

Answer:

72.25

Step-by-step explanation:

Triangles are 1/2(base x height), or (base x height) / 2.

17 x 8.5 = 144.5

144.5 / 2 = 72.25

74.25 square inches.

The formula to find the area of a triangle is A = 1/2(b)(h). (b being base and h being height)

A=1/2(17)(8.5)
A=1/2(144.5)
A= 72.25 :)

Help me if you want to be worshiped UvU

Answers

Answer:

48

Step-by-step explanation:

To find the mean, add up all the heights

(49+47+46+45+53) =240

Then divide by the number of students

240/5 =48

The mean is 48

Answer:

48

Step-by-step explanation:

So what you are trying to do here is to find the mean.

The means just means the average or norm.

To find the mean, you first add up all the numbers on the table to find a total.

So then you divide the total that you have by the numbers of values that you added together which may sound confusing but let me show you so it will make more sense.

So to find the number of values that you added together, you just count the student - A, B, C, D ,E or 49, 47 , 46, 45, 53. You just count the numbers that you have there in total which is again, 5.

Anyways since the total of the numbers when added up is 240 you just divide that by 5.

So when you do that your answer should be 48.

Noooo Linnkkkkkk Rodney ordered a large sub sandwich. He ate 1/4 of the sandwich on monday and 1/3 of it on tuesday. Which equation shows how to find how much of the sandwich Rodney ate ate in all?
A. 1/4 + _ = 1/3
B. 4/7 + 5/7 = _
C. 4/12 + 5/12 = _
D. 3/12 + 4/12 = _

Answers

Answer:

d.

Step-by-step explanation:

3/12 simplified is 1/4, 4/12 simplified is 1/3. they want to know how much rodney ate total, so simply it's the same as 1/4 + 1/3 ;; just with common denominators so it is easier to solve.

edit: the __ represents the total on how much they ate.

The equation used to describe total amount of sandwich he ate will be

3 / 12  +  4 / 12  = 7  /  12.

What is an equation?

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

It is given that:-

He ate 1/4 of the sandwich on Monday and 1/3 of it on Tuesday

So the equation to calculate the total amount of sandwiches he ate will be:-

=  1  /  4  +  1  /  3  

We can also write the above equation as:-

=  3  /  12  +  4  /  12

= 7  /  12

Therefore the equation used to describe the total amount of sandwich he ate will be  3 / 12  +  4 / 12  = 7  /  12.
