How do you think inequalities are different from equations you have worked with before?
Answers
Answer:
The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.

Answer:yes they are different
Step-by-step explanation:
1. An equation is an equality of two mathematical expressions. That's why it has an equal(=) sign . For example:
12x=10x +2x
Or
3x+4y=5
2. While an inequation is an inequality of two expressions and here the greater than and lower than signs are used with equal sign i.e. >,< or=
For example
4y+5a > 5
Or
8a< 7b

39=3*13
12=3*2*2
so (3*13)/(3*2*2)
we can factor out the 3/3 or 1

Answer:
In the example, 20 is the dividend, five is the divisor, and four is the quotient. Unlike the other basic operations, when dividing natural numbers there is sometimes a remainder that will not go evenly into the dividend; for example, 10 ÷ 3 leaves a remainder of one, as 10 is not a multiple of three.
Step-by-step explanation:
Final answer:
Division statements that result in a quotient of 20 include equations where any number is divided by 20 or a multiple of 20 is divided by its factor. Examples are 400 ÷ 20 = 20, 600 ÷ 30 = 20, and 280 ÷ 14 = 20.
Explanation:
In division when we have a quotient of 20, we know that any number divided by 20 or a multiple of 20 divided by its factor will yield this quotient. To put that into a more practical scenario, let's look at a few division statements with a quotient of 20:
- 400 ÷ 20 = 20
- 600 ÷ 30 = 20
- 280 ÷ 14 = 20
These are just a few examples. As you can see, each of these division statements results in a quotient of 20, meaning, if you divide the first number by the second number, your answer (quotient) will be 20.

78/8=9.75(divide by 8 because 80%/8=10%)
9.75*10=97.5
97.5*.8=78
75% of 104 is 78 which is also 80% of 97.5
Your answer is 97.5
Final answer:
Using an equation, we found that 75% of 104 is equal to 80% of 97.5. The number that made these percentages equal was found to be 97.5.
Explanation:
To find the unknown number, we can setup an equation using percentages and solve for the unknown. The problem states that 75% of 104 is the same as 80% of some number. So, we can write this as an equation: 0.75 * 104 = 0.80 * X. Solving this equation will give the value of X.
First, calculate the value of 75% of 104, which is 0.75 * 104 = 78. Now, replace this value into the equation: 78 = 0.80 * X. To solve for X, we divide 78 by 0.8, which gives us 97.5.
Therefore, 75 percent of 104 is the same as 80 percent of 97.5.

take 3 and 5 and multiply it by 30
3*30=90
5.5*30=165
then divide them both by 12 to convert inches to feet
90÷12=7.5
165÷12=13.75
then multiply both dividends together
7.5*13.75=103.125
then round to the nearest whole number
