2x - 4(x + 2) = -2X-8
devlian [24]

Answer:

x= 0

Step-by-step explanation:

in order to find the value of x in the 2x - 4(x + 2) = -2X-8

we are going to apply bodmas rule by first opening the bracket

we have,

2x-4x-8 = 2x -8

we proceed to collect the like terms

2x -4x-2x = -8 +8

-4x = 0

divide both sides by -4

-4x/-4 = 0/-4

x= 0

the inequality below compares two rational numbers -6/18-17/27 if two numbers were plotted as values on a horizontal number line
Lyrx [107]

Correct question is;

The inequality below compares two rational numbers.

-6/18 > -17/27

If the two numbers were plotted as values on a horizontal number line, which statement would be true?

A) Both numbers lie to the right of 0, and −6/18 lies to the left of −17/27

B) Both numbers lie to the left of 0, and −6/18 lies to the left of −17/27

C) Both numbers lie to the right of 0, and −6/18 lies to the right of −17/27.

D) Both numbers lie to the left of 0, and −6/18 lies to the right of −17/27

Answer:

Option D

Step-by-step explanation:

In writing inequality on a number line, any number that is negative will lie to the left of zero while any number that is positive will lie to the right of zero.

Now in this case they are both negative, so they will lie to the left of zero.

Also, the number that is greater will lie to the right of the lesser number.. In this case -6/18 > -17/27. Thus, -6/18 will lie to the right of -17/27

Thus, option D is correct

Alexandra wanted to make a doormat to place at her front door. Below is the scaled drawing she will use to make it.How much mate
pychu [463]

Answer:

112.5 pi

Step-by-step explanation:

hi, to find this we need to know the formula for the area of a circle. it is:

a=pi*radius^2

so the radius is 30/2=15

now we can just plug 15 in to find the area.

a=pi*15^2

a=225pi

now, that is the area for the full circle, but here it is a semi circle, so we just divide 225 pi by 2 to get

112.5 pi, or 112.5π
