How is subtracting like fractions similar to adding like fractions

Answers

Answer 1

Answer: Because they both have the same rule. They have to have the same denominator.

Answer 2

Answer: Well,

Adding and subtracting like fractions are similar in that both cases simply require you to add the numerators. This is opposed to adding and subtracting non-like fractions because you have to convert them into like fractions.

Sharon earns $15 per item she sells plus a base salary of $75 per week write and solve an inequality to find out how many items she must sell to earn at least $750 per week provide your conclusion as a complete sentence

Answers

so 15 dollars per item plus 75 dollars a week is 15x + 75 where x is the number of items sold.

if she sells one item, x = 1 and she will make:

15 (1) + 75 = 90 dollars.

so that's not enough to get 750, you need more money. how? more x! how much more is enough though?

well 15x + 75 needs to = 750

so 15x + 75 = 750

move 75 over to the right and get

15x = 675

now divide both sides by 15

x = 45

so Sharon needs to sell a MINIMUM of 45 per week to earn at least 750 dollars.

saying minimum is important because the problem says at LEAST $750.

True or false: any nonzero integers, the product and the quotient have the same sign. Why?

Answers

False. This is because no matter what the number is, the properties of multiplication and division stay the same. So, if one odd and even number multiply/divide, then the answer will be negative. But, if two numbers of the same sign (both either negative or positive) are divided/multiplied, they will both be positive. Therefore, the result is not always the same sign as the starting integers

Hope this helped! :D
