Answers

Answer:

Step-by-step explanation:

CD HI MN RS we have to find next letters.

To find next letters first we write alphabets to find the relation in this sequence.

A B C D E J G H I J K L M N O P Q R S T U V W X Y Z

As we can see after 3 letters two letters have been taken.

so to continue the sequence next letters would be WX,

I think your answer is WX. The pattern from what I can tell is: ab CD efg HI jkl MN opq RS tuv WX yz.

4|x+5|=20
Thanks for the help

Answers

4 |x = 5| = 20

First, divide both sides by 4. / Your problem should look like: $|x + 5| = 5$
Second, simplify $(20)/(4)$ to 5. / Your problem should look like: $|x + 5| = 5$
Third, break the problem into 2 equations. / x + 5 = 5 and -(x + 5) = 5
Fourth, solve x + 5 = 5. /
Cancel 5 on both sides. / $x = 0$
Fifth, solve -(x + 5) = 5 /
Simplify brackets / $-x - 5 = 5$
Add 5 to both sides / $-x = 5 + 5$
Add 5 + 5 / $-x = 10$
Multiply both sides by -1 / $x = -10$
x = -10
Sixth, collect the solutions to the problems. / Your problem should look like: $x = -10, 0$

Answer: x = -10, 0

4Ix+5I=20
$4(-(x+5))=20$
$4(-x-5)=20$ distributhing 4 through parantheses
$-4x-4*5=20$
$-4x-20=20$
$-4x=20+20$
$-4x=40$ divide by -4
$x= (40)/(-4)$ simplify
$x=-10$
The answer is : - 10

Costs change from $240 to $320. what is the percent change? also how do you do this?

Answers

A change from 240 to 320 represents a positive change (increase) of 33.33333333333333% Use the formula found below on this webpage to find the percent change by replacing the given values: Percent change = [(240 - 320) / 240] x 100 = 33.33333333333333 % (increase) Where: 240 is the old value and 320 is the new value. In this case we have a positive change (increase) of 33.33333333333333 percent because the new value is greater than the old value.
