Answer:

The simplified equivalent expressions for given expression as below:

A) 2x+10x=12x

B) -4(3x-10)+5(2-6x)=-42x+50

C) 2(x-4)+x=3x-8

D) -3-7(3-4x)+8x=36x-24

Step-by-step explanation:

A) Given expression is 2x+10x

To simplify the expression using distributive property a(x+y)=ax+ay

2x+10x=12x (adding the terms)

B) Given expression is -4(3x-10)+5(2-6x)

To simplify the expression using distributive property a(x+y)=ax+ay

-4(3x-10)+5(2-6x)=-12x+40+10-30x

-4(3x-10)+5(2-6x)=-42x+50 (adding the like terms)

C)  Given expression is 2(x-4)+x

To simplify the expression using distributive property a(x+y)=ax+ay

2(x-4)+x=2x-8+x (adding the like terms)

2(x-4)+x=3x-8

D) Given expression is -3-7(3-4x)+8x

To simplify the expression using distributive property a(x+y)=ax+ay

-3-7(3-4x)+8x=-3-21+28x+8x (adding the like terms)

-3-7(3-4x)+8x=-24+36x

-3-7(3-4x)+8x=36x-24

What is the mean of this table
suter [353]

Answer:

The mean is 77.8125

Step-by-step explanation:

The mean is the average of the numbers. It is very easy to calculate and get. All you have to do is add up all the numbers and divide it by how many numbers there are.

80 + 90 + 81 + 86 + 100 + 77 + 75 + 96 + 65 + 87 + 58 + 80 + 36 + 73 + 70 + 91 = 1245

\frac{1245}{16} = 77.8125

EASY BRAINLIEST ANSWER ASAP!!
elena-14-01-66 [18.8K]

Answer:

  1. (0, 4)
  2. (-1, 16/ 3)
  3. (-9/ 2, 10)

Step-by-step explanation:

In an ordered pair the term before the comma is the x variable and the term after the comma is the y variable.

1.

4x + 3y = 12 . . . . . .(0, _)

here were given the x variable

finding the other term

4× 0 + 3y = 12

3y = 12

y = 4

therefore the ordered pair is <u>(0, 4) </u>

2.

. . . . . . . (-1, _)

here were given the x variable

4 × -1 + 3y = 12

3y = 12 + 4

3y = 16

y = 16/ 3

ordered pair is <u>(-1, 16/ 3)</u>

3.

. . . . . . . . (_, 10)

here were given the y variable

finding the other term

4x + 3 × 10 = 12

4x + 30 = 12

4x = 12 - 30

4x = -18

dividing both sides by 2

2x = -9

x = -9/ 2

ordered pair is<u> (-9/ 2, 10)</u>
