The equation 2x + 2 = x+5 is modeled below. x What value of x makes the equation true? A X = 1 B Y = 3 C x = 5 D X = 7

Answers

Answer 1
B Y = 3

2 x + 2 - x = 5
2 x - x = 5 - 2
x = 5 - 2
x = 3
Answer 2

Answer:

b

Step-by-step explanation:

2x + 2 = 1x + 5

combine the like terms.

2x + 2 = 1x + 5

-2x        -2x  

------------------

2 = -1x + 5

isolate the -1x.

2 = -1x + 5

-5          -5

----------------

-3 = -1x

solve for x.

-3/-1 = -1x/-1

3 = x

so b. correct me if any of this is wrong.

C 1/2
D 3/4​

Answers

1/4

Spinning it once would be 1/2 but then twice would double this possibility, making it 1/4

The probability of spinning an odd number both times is 1/4

What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Spinning it once would be 1 / 2 So the probability for spinning two times giving an odd number will be:-

P   =   1  /  2  x   1   /   2  =  1   /  4

Therefore the probability of spinning an odd number both times is 1/4

The variable (a) represents the number of equal parts into which the (Circle) is divided. The variable (b) represents the number of (Degrees).

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

The equation 360°÷a=b can be used to find an angle measure in a circle.

360° = ab.

Here, a and b are the variables of the equation. and 360 degrees is the complete angle of the arc of a circle.

The variable (a) represents the number of equal parts into which the (Circle) is divided. The variable (b) represents the number of (Degrees) in each part.

======================================================

Explanation:

Let's pick on the horizontal sides. Divide the image length Y'Z' = 9 over the corresponding preimage length YZ = 12 to get

(Y'Z')/(YZ) = 9/12 = 3/4 which is the scale factor

The scale factor is less than 1, meaning the image's lengths are shorter compared to the preimage's corresponding lengths.

-----------------

Alternative Paths:

You can pick any other pair of corresponding sides to get the same result:

(X'Y')/(XY) = (7.5)/(10) = 75/100 = 3/4(Z'X')/(ZX) = 6/8 = 3/4

Answer:

[tex]scale ~factor= Z'Y'/ZY[/tex]

Craig is organizing a neighborhood party for his scout troop. He needs to deliver fliers to all of the houses in the neighborhood. There are 13 streets with 12 houses, 14 streets with 11 hours, and 8 streets with 13 houses. If there are 18 boys in his scout troop helping Craig deliver the fliers, how many fliers should each pair of boys get?

Answers

Answer:

Each pair of boys should get 46 papers.

Step-by-step explanation:

multiply houses by streets to find the total number of papers:

13(12)=156

15(11)=154

8(13)=104

156+154+104=414

Because it say they will be in pairs you must divide the boys:

18/2=9

Then to find how many papers each boy must take divide total number of papers by the pairs of boys:

414/9=46

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.
