Simplify the following expression:

2x − 2y + 5z − 2x − y + 3z NEED HELP PLZ :(

A x − 3y + 8z
B 2x − 2y + 8z
C 3y + 8z
D−3y + 8z

Answers

Answer 1

Answer:

D) -3y + 8z

Step-by-step explanation:

2x - 2y + 5z - 2x - y + 3z

first, group the same variables together.

2x - 2x - 2y - y + 5z + 3z

then, this step which I don't have a name for.

2x - 2x = 0x.

-2y - y = -3y

5z + 3z = 8z

0x - 3y + 8z

or, -3y + 8z

Answer 2
The answer would be d !

-1/2y=1/2+5 what is the solution?

Answers

Answer:

-11

Step-by-step explanation:

-1/2y=1/2+5

- 1/2 y = 1+10 (by taking lcm)

               2  

 [tex]\frac{-1}{2}[/tex] x 2y = 11

y = -11

[tex] \frac{ - 1}{ \: \: \: 2} y = \frac{1}{2} + 5[/tex]

[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{1}{2} + 5[/tex]

[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{11}{2} [/tex]

[tex]y = \frac{11}{2} \div \frac{ - 1}{ \: \: \:2} [/tex]

[tex]y = \frac{11}{2} \times \frac{ \: \: \: 2}{ - 1} [/tex]

[tex]y = \frac{ \: \: 22}{ - 2} [/tex]

[tex]y = - 11[/tex]

The value of y = -11

Therefore :-

[tex] \frac{ - 1}{ \: \: \:2} \times - 11 = \frac{1}{2} + 5[/tex]

When the number of bricks is multiplied by 2, the length is multiplied by
1.
2.
3.
6.

Answers

Answer:

The length will be multiplied by 2.

Step-by-step explanation:

By looking at the first and third ratio, we know that the no. of birck have been multiplied by 2 and the length has also been multiplied by 2 .

So when the number of bricks is multiplied by 2, the length is multiplied by 2

Answer:

2

Step-by-step explanation:

Using the table we observe the points

(6, 3) and (12, 6)

The number of bricks doubled

6*2 = 12, and

The length is doubled accordingly

3*2 = 6

So the answer is 2

Answers

Answer:First one is x=1

second is y=22

Step-by-step explanation:

Answer:

[tex]x = \frac{6}{7}[/tex]  y = 22

Step-by-step explanation:

For first equation:

Subtract 8 from each side, so it now looks like this: 7x = 6Divide each side by 7 to cancel out the 7 next to x. It should now look like this: [tex]x = \frac{6}{7}[/tex]  

For second equation:

Simplify: y - 12 = 10Add 12 to each side, so it now looks like this: y = 22

The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression, 2.75+0.10x, where x is the number of years since 1980. Which part of the expression corresponds to the cost of movie tickets in 1980?

Answers

Answer:

$4.7

Step-by-step explanation:

step one:

Let the cost be y

to solve for the cost of  a movie ticket, we need to solve the expression

y=2.75+0.10x

step two:

given that x is the number of years between 1980-2000

the number of years is 20years

put x= 20 in the expression for the cost we have

y=2.75+0.10(20)

y=2.7+2

y=$4.7

B
m = -24/1
с
m = -4/15
D
m = 4/15

Answers

Answer:

The answer is option C

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(8, 10) and (-7, 14)

The slope is

[tex]m = \frac{14 - 10}{ - 7 - 8} = \frac{4}{ - 15} = - \frac{4}{15} \\ [/tex]

We have the final answer as

[tex] - \frac{4}{15} \\ [/tex]

5. m∠A = 26

6. m∠D = 118

7. m∠E = 43

8. m∠H = 85

Step-by-step explanation: complementary= 90 supplementary = 180

5. (2x - 8) + (4x +4) = 90

6x - 12 = 90

6x = 102

x = 17

m∠A = 2x - 8  

m∠A = 2(17) - 8 = 26

6. (2x + 18) + (5x + 8) = 180

7x + 26 = 180

7x = 154

x = 22

m∠D = 5x + 8

m∠D = 5(22) + 8 = 118

7. (2x + 15) + (3x + 5) = 90

5x + 20 = 90

5x = 70

x = 14

m∠E = 2x + 15

m∠E = 2(14) + 15 = 43

8. (5x - 20) + (4x + 7 ) = 180

Gianna, Jada, and Brittney and a bunch of other friends had a horseshoe competition. Jada and Brittney were eliminated after two rounds because they were too busy texting but Gianna went onto round eight to win 47 pieces of gum. Later, she gave two to each of her friends. She only has 1 remaining. How many friends does she have?

Answers

Answer:

23 friends

Step-by-step explanation:

Let the number of friends she has = x

Total number of gum = 47 pieces

She gave 2 each to her friends, hence:

2x + 1 = 47

2x = 47 - 1

2x = 46

x = 46/2

x = 23

Therefore, the number of friends she has is 23

m∠RMS = 20°

Step-by-step explanation:

Find ∠RMS and look at the two values it crosses.

∠RMS crosses through 180 and 160.

Find the difference between the two values to get the measure:

180 - 160 = 20°

So, m∠RMS = 20°

(Its also an acute angle.)

Answer:

20

Step-by-step explanation:

The mistake is in using 160 as the answer. It isn't.

The angle is very small well under 90. It is acute.

The horizontal part of the angle is on 180 degrees of the protractor.

Therefore the angle size is 180 - 160 = 20 degrees.

I also understand that you have identified six finalists who are highly qualified for the position, three of whom are deaf. I have a deep interest in disability civil rights. Over the past few years I have worked with many national and local organizations run by and for disabled people, including the National Council on Independent Living, the National Council on the Handicapped, Capitol People First of Sacramento and the Association on Handicapped Student Service Programs in Post-Secondary Education. I have also had many conversations with disabled leaders, including deaf persons, throughout the United States. And my office has served as the focal point for the development of the Administrations disability policy. From this experience, I have become aware of the two basic principles underlying the disability rights movement; the right of disabled people to control their own lives and the right to integration and involvement in society. Gallaudet University has a critical role to play in advancing these principles. It is held in the highest regard by deaf people throughout the United States and the world. It provides an excellent education and a meaningful future for thousands of deaf persons. More importantly, Gallaudet University is a symbol of leadership and opportunity, not only for deaf people, but for all of us. In the last two decades our society has undergone a quiet revolution. The Congress, the Courts and the Administration have strongly supported the right of people with disabilities to hold positions of trust and leadership. Our government has enacted numerous laws to ensure that disabled people are ensured equality of opportunity. Accordingly, as an entity funded by the Federal government, Gallaudet has a responsibility to set an example and thus to appoint a President who is not only highly qualified, but who is also deaf. I hope that the Trustees will keep Gallaudets critical leadership position in mind when they make their decision.
