Eight less than a number is six more than twice the same number.<br> I need the number.

mariarad [96]

The answer is -14

Explanation:

x - 8 = 2x + 6

We move all term to the left

x - 8 - ( 2x + 6 ) = 0

We get rid of parentheses

x - 2x - 6 - 8 = 0

We add all the numbers together, and all the variables

-1x - 14 = 0

We move all terms containing x to the left, all other term to the right

-x = 14
x = 14/-1
x = -14

Form a sequence that has two arithmetic means between -13 and 89.

scoray [572]

It would be D. If you add all the numbers (-18, -81, 144) and divide it by 3 then you would get -81. I hope I helped!

Name two fractions between 4/8 and 4/9

kumpel [21]

4/9 is smaller than 4/8 so the other fractions should be 4/8.____

This is what I did:

I used the fractions 4/8.5 and 4/8.4

Now we need to get rid of the decimal point for each of those fractions.

Find out what number you need to multiply the denominator so it is a whole number, not a decimal.

Take that number and multiply it by both numerator and denominator.

8.5 x 2 = 17
4/8.5 = (4*2)/(8.5*2) = 8/17 (This is your first fraction)

8.4 x 5 = 42
4/8.4 = (4*5)/(8.4*5) = 20/42 (This is your second fraction.

Which expression is equivalent to 2.2 − 0.5(0.6x − 1.8) ?

yawa3891 [41]

Answer:

D is equivalent to the expression.

Step-by-step explanation:

The expression that is given equals 2.8, or 2.8x.

A. This expression equals 1.6x, and 1.6x is not equivalent to 2.8x

B. 0.3x + 3.1 = 3.4x. This doesn't have the answer of 2.8x.

C. 1.3 - 0.3x = 1 or x.

D. 3.1 - 0.3x = 2.8x. D is the answer.
