x + (- 8) = 3 x + 6

x- 8 = 3x +6

First,

Add 8 positive unit tiles to both sides

x- 8 + 8 = 3x +6 + 8

x= 3x +14

Which expression represents a simplified form of the algebraic expression shown below?

1/2(2x +4) + x

Question 2 options:

x + 2


2x + 4


2x + 2


3x + 2

Answers

Answer:

2x+2

Step-by-step explanation:

First you want to distribute

1/2(2x+4)

ignore the ending +x for now

Distribute 1/2 to 2x

since 2*1/2 is 1 then we get 1x, or x

next distibute 1/2 to 4

you get +2 since 1/2*4=2

so what you end up with is x+2

However, you still have the +x from the beginning

x+2+x

Imagine that each x has a one in front

1x+2+1x

now re arrange so the common factors are near each other

1x+1x+2

now add the common factors

1x+1x=2x

and finally you get 2x+2

the equation for the triangle can be this

2(2x+3)+10x-5 = 180

Answer:

x= 16

x=1.5

Step-by-step explanation:

Simplifying

3x + -0.5 = 0

Reorder the terms:

-0.5 + 3x = 0

Solving

-0.5 + 3x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '0.5' to each side of the equation.

-0.5 + 0.5 + 3x = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0

0.0 + 3x = 0 + 0.5

3x = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5

3x = 0.5

Divide each side by '3'.

x = 0.1666666667

Simplifying

x = 0.1666666667

Simplifying

2x + 3 = 0

Reorder the terms:

3 + 2x = 0

Solving

3 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + 2x = 0 + -3

2x = 0 + -3

Combine like terms: 0 + -3 = -3

2x = -3

Divide each side by '2'.

x = -1.5

Simplifying

x = -1.5

B. 28 times
C. 24 times
D. 32 times
Which one is right? Please explain your answer.
HELP ME PLS

Answers

The answer is B about 28 times

Step-by-step explanation:

If he bounces the ball 20 times in 30 seconds then he bounces it once every 1.5 seconds if you multiply 1.5×6 you get 9 so you add 9 to 20 to get 29 and you choose the closest answer because is says approximately so you chose B.28

it’s C because 30 divided by 20 is 1.5, and 36 times 1.5 is 24
