Answers

Answer 1

 

3x + 2y = 11

2x + 3y = 17

--------------------  We add the equations

5x + 5x = 28

5(x + y) = 28

x + y = 28 / 5    | ÷ 2

(x + y) / 2 = (28 / 5) / 2

(x + y) / 2 = 28 / 10

Average =   (x + y) / 2 = 2.8  Corect answer:   B

In three to four sentences, describe how you can act financially responsible.

Answers

To be financially responsible, you can keep track of how much money you spend by keeping a checkbook updated. When doing bills, buying groceries and clothes, and spending money on other activities, you use the recipes to record your spendings in the checkbook. Another way to stay financially responsible is to use a debit card more than a credit. When using a credit card, you're borrowing the Bank's money rather than your own and you have to pay them back. Slowly, that can cause more problems when late fees are added, or worse, your interest rates begin to fluctuate.

if the sum of five consecutive even integers is 740 what is the largest of these integers

Answers

The answer is 152. I hope that helped!

if the sum of five consecutive even integers is 740, the largest of these integers will be 152.

What is an integer?

A whole number, as opposed to a portion that might be positive, negative, or zero, is an integer. Imaginary numerals, halves, and decimals are all part of the non-integer instances.

There are 5 consecutive even integers according to the given information:

So, the difference between each number who are consecutive will be 2

Letting the first number be x

Then another five consecutive numbers will be:

x, (x + 2), (x + 4), (x + 6), (x + 8)

As the question is asking to find the sum of the numbers, the sum is given as 740.

So,

(x + x + 2 + x + 4 + x + 6 + x + 8) = 740

5x = 740 - 20

x = 144

And the highest number among the five integers will be

x + 8 = 152
