The value of the inequality equation is x < 22

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

x - 8 < 14   be equation (1)

Now , the value of equation can be simplified as

x - 8 < 14

Adding 8 on both sides of the equation , we get

x < ( 14 + 8 )

The value of x < 22

Therefore , the value of x is always less than 22

Hence , the value of the inequality equation is x < 2

A skatin rink sold 66 tickets. of these 2/3 were children's tickets, and the rest were adult tickets. What total number of adults tickets were sold?

Answers

children=2\3 x 66=44
adult=66-44=22
answer=22 tickets 
If 2/3 of the tickets sold were kid tickets, then 1/3 was adult tickets. 1/3 of 66 is 22 so there were 22 adult tickets sold and 44 children tickets sold. Hope this helps!!

jasmines cd collection is 3/8 jazz 1/4 rap and the rest is rock music what is the fraction of rock music

Answers

rap - 1/4
jazz - 3/8
rock - x
all - 1


jazz + rap + rock = all

3/8 + 1/4 + x = 1
3/8 + 2/8 + x = 1
5/8 + x = 1
x = 1 - 5/8
x = 3/8

answer: rock - 3/8

Mari makes bows for floral arrangements. She uses 1/8 of a yard ribbon for each bow. How many bows can she make from 2 spools that each has 24 yards ribbon?

Answers

First, you need to find out how much ribbon she has total. Because there are two spools, you multiply 24 x 2. The answer for that is 48. Then you have to figure out how many bows she can make. Each bow uses 1/8 of a piece of yard of ribbon, so you can divide 48 by 8. Your answer would then be 6 bows.

Here are the equations.

24*2 = X

X/8 = B

Where X represents the yards of ribbon available and B represents the number of bows that Mari can make.

A picture frame is 9 inches long and 6 inches wide. It can display a picture 6 inches long and 4 inches wide. What is the area of the picture frame?

Answers

Answer:

30 inches squared

Step-by-step explanation:

First, find the area of the entire frame using length times height. 9*6 is 54 inches squared. Then, find the area of the middle space the same way. 6*4 is 24 inches squared. Lastly, subtract the middle from the entire frame's area. 54-24 is 30 inches squared.

Answer:

30 in^2

Step-by-step explanation:

Frame

Length = 9

 Width = 6

9 * 6 = 54in^2 (Multiply to get 54)

Picture

Length = 6

 Width = 4

6*4 = 24in^2            ( Multiply to get 24 )

54 - 24 = 30in^2      ( Minus 24 from 54 to get 30)

Formula l*w

It's length times width NOT length times hight like the other person said

Which statement is true for the equation 4x - 4x - 5= -5No solution
One solution
Two solutions
Infinitely many solutions

Answers

Answer: Infinitely many solutions

Step-by-step explanation:

1. Cancel −5 on both sides.

4x−4x=0

2. Simplify 4x−4x to 0.

0=0

3. Since both sides equal, there are infinitely many solutions.

One month, Jon worked 3 hours less than Chaya, and Amgelica worked 4 hours more than Chaya. Together they worked 196 hours. Find the number of hours each person worked.

Answers

Okay lets look at the problem first
so Chaya is our X Value
and we know that the total is 196
lets divide the total by 3
so we have 65.1
lets forget the point one for now
know if each person worked 65 hours this would be over 
but we know that Jon Worked 3Hours less then Chaya that would put him at 62
Know we need to put that 3 hours to the side and remember we havnt used it yet
And we know that Amgelica worked 4 more hours then Chaya andwe still have 4 hours left over so that puts her at  69 hours
so Jon (a) worked 62 hours
Amgelica (b)worked 69 hours 
and Chaya (c)at 65
a+b+c=196
62+69+65=196
I hope this helped
