Find three consecutive odd integers such that the sum of the smallest and four times the largest is 61. Please list the numbers from least to greatest with just a space in between

Answers

Answer:

9,11,13

Step-by-step explanation:

Given: sum of the smallest integer and four times the largest integer out of three consecutive odd integers is 61

To list: numbers from least to greatest

Solution:

Let the three consecutive odd integers be x,x+2,x+4.

According to question,

x+4(x+4)=61\nx+4x+16=61\n5x=61-16\n5x=45\nx=9

So, the integers are x=9,x+2=9+2=11,x+4=9+4=13

Numbers from least to the greatest: 9,11,13

Which of these is an example of using financial reserves for a occasional expense? a. You know that your car will need a tune-up and other routine maintenance every winter, so you save a little money every month in preparation and use the saved money to pay when winter comes around. b. You are hit with a summer heat wave and your utility bill spikes, so you use your credit card to pay the bill and pay off the balance over the next few months. c. You graduate college and need to start paying back your student loans, so you devote some of your income every month to paying down the debt. d. You are never quite sure how much money you spend on food every month, and every so often you need to pull a tiny bit from your retirement fund to pay for groceries.

Answers

The correct answer is:

A) You know that your car will need a tune-up and other routine maintenance every winter, so you save a little money every month in preparation and use the saved money to pay when winter comes around.

Explanation:

An occasional expense is one that does not happen every month. Winter maintenance would count as occasional. Saving a little money each month to make sure you have enough to perform winter maintenance is using financial reserves for occasional expenses.

A cab charges $1.45 for the flat fee and $0.55 for each mile. Write and solve an inequality to determine how many miles Ariel can travel if she has $35 to spend. $1.45 + $0.55x ≥ $35; x ≥ 61 miles $1.45 + $0.55x ≤ $35; x ≤ 61 miles $0.55 + $1.45x ≥ $35; x ≥ 23 miles $0.55 + $1.45x ≤ $35; x ≤ 23 miles

Answers

Answer:

Step-by-step explanation:

To answer this question you first need to know what the inequality symbols mean!

≤ Less than or equal to

≥ Greater than or equal to

So if Ariel has $35 this mean the following:

$1.45 is the flat fee or y-intercept

$0.55 is the slope

This mean the following:

$1.45 + $ 0.55x ≤ $35

$0.55x ≤ $33.55

x≤61
