Before answering this question, you need to know 2 types of expenses:

1. Fixed

2. Variable

Fixed expenses is the obligatory expenses which we do not have much control, and usually we have to pay in a certain amount of type. For example rent, student loan, grocery etc. In this case, the only fixed expenses is rent which you have to pay every month.

The other options: entertainment, clothing,food and gas are considered variable as it is not obligatory and you can choose how much you would spend.

4a-b-c

Step-by-step explanation:

we first look at the letters of each number. if there is only a letter, there is an imaginary 1 in front of it. we need to make sure that we add the numbers that have the exact same letters because they are known as like terms. we cannot add 6a and 4b because the letters are different and they are known as unlike terms. When we add numbers with the same letter ONLY the number changes

His parents pay Tyler $ 0.75 to do the laundry and $ 1.75 to mow the lawn. In one month, he does the laundry 6 more times than h

zhuklara [117]

Answer: Tyler mowed the lawn 4 times

Step-by-step explanation:

Let x = number of times that he does laundry

Let y = number of times that he mows the lawn

In one month, he does the laundry 6 more times than he mows the lawn. This means

x = 6 +y

Tyler's parents pay him $ 0.75 to do the laundry and $ 1.75 to mow the lawn. If his parents pay him $ 14.50 that month, it means that

0.75x + 1.75y = 14.5 - - - - - - -1

Substituting x = 6+y into equation 1, it becomes

0.75(6 + y) + 1.75y = 14.5

4.5 + 0.75y + 1.75y = 14.5

0.75y + 1.75y = 14.5 - 4.5

2.5y = 10

y = 10/2.5 = 4

x = 6 + y = 6 + 4

x = 10

There are 300 apples and peaches for sale at a farmers market. The ratio of the number of apples to the number of peaches is 7:8

Sidana [21]

Answer:

The ratio of the reaming apples to peaches is 3 : 4

Step-by-step explanation:

* Lets solve the problem

- There are 300 apples and peaches

- The ratio of the number of apples to the number of peaches is 7 : 8

- To find the the numbers of apples and peaches add the terms of the

ratio and then divide the total number of apples and peaches by this

sum and then multiply each terms of the ratio by this quotient

∵ The ratio of apples to peaches = 7 : 8

∴ apple : peach : sum

7 : 8 : 15

? : ? : 300

∴ The number of apples = (300 ÷ 15) × 7 = 20 × 7 = 140 apples

∴ The number of peaches = (300 ÷ 15) × 8 = 20 × 8 = 160 peaches

- 50 apples and 40 peaches are sold

∴ The remaining number of apples = 140 - 50 = 90 apples

∴ The remaining numbers of peaches = 160 - 40 = 120 peaches

- To find the ratio simplify the numbers to its simplest form

∵ There are 90 apples and 120 peaches

∴ apple : peach

90 : 120 ⇒ divided both by 10

∴ 9 : 12 ⇒ divide both by 3

∴ 3 : 4

∴ The ratio of the reaming apples to peaches is 3 : 4
