Answer:

Hi there!

The answer to this question is x=4.

Step-by-step explanation:

you first want to get all the x's on one side, in order to do that you add six on both sides to get 4x+2x=24

next you add 4x to 2x because they both end in the variable 'x' to get 6x

then you divide 6 on both sides to single out 'x' and you get 4

Answer:

x = 4

Step-by-step explanation:

Given

4x - 6 + 2x = 18 ← simplify left side by collecting like terms

6x - 6 = 18 ( add 6 to both sides )

6x = 24 ( divide both sides by 6 )

x = 4

vodomira [7]

Answer:

  • INSTRUCTION FOLLOWED: <u>write the sum as a mixed number where the fractional number is less than one.</u>

5/5 out of the 7/5 make <u>ONE whole</u> while 2/5 is left over.

The <u>ONE whole</u> is added to nine to make 10 and the remaining 2/5 is also added to the 10 hence 9 7/5 = 10 2/5

Find a solution to the linear equation - 2x – 2y = 8 by filling in the boxes with a valid value of x and y.
adoni [48]

Answer:

-2(-4)-2(0)=8

Step-by-step explanation:

Given

2x - 2y = 8

Required

Gaps: -2( )-2( )=8

<em>Fill in in the gaps</em>

The are numerous solutions to this.

One of them is:

Assume y = 0.

So, we have:

-2x - 2*0 = 8

-2x - 0 = 8

-2x = 8

Divide through by -2

\frac{-2x}{-2}= \frac{8}{-2}

x= -4

Fill in the gaps with these values of x and y respectively:

Hence; one solution is: -2(-4)-2(0)=8

CAN SOMEONE HELP?????????
ivann1987 [24]

The median (half-above and half-below) could not have changed, because "corrected value was still lower than any other salary" does not change the position of that observation (still least) in the sorted list of salaries.
