In rectangle KLMN, KM = 10x+24 and KN = 64 find x

Answers

Hi there, I don't know if I am right but I will try to solve this, 10x+24=64, subtract 24 from both sides, 10x+24-24=64-24=10x=40, divide both sides by 10, 10x/10=40/10, x=4

Answer:

The answer is 4

Step-by-step explanation:

10x+24=64

10x=64-24

10x=40

x=40/10

x=4

Kenneth has entered a check payment of $350.25 in his checkbook. If the old balance was $545.95, what is his latest balance? A.)$896.25
B.)$195.70
C.)$195

Answers

Answer:

The correct option is B.

Step-by-step explanation:

The old balance of kenneth's checkbook was $545.95.

Kenneth has entered a check payment of $350.25 in his checkbook.

It means the balance of checkbook is reduced by $350.25.

The latest balance of check book is

$\$545.95-\$350.25=\$195.70$

Therefore the latest balance of kenneth's check book is $195.70. Option B is correct.

the perimeter of a triangle is 8x+3y. The length of two sides of the triangle are 4x+y and 2x-3y. Find the measure of the third side of the triangle.

Answers

Perimeter = Sum of three sides.

Let the third side be = t

Perimeter = 8x + 3y

8x + 3y = (4x + y) + (2x - 3y) + t

8x + 3y = 4x + y + 2x - 3y + t

8x + 3y = 4x +2x + y - 3y + t

8x + 3y = 6x - 2y + t

8x - 6x + 3y + 2y = t

2x + 5y = t.

Therefore third side = 2x + 5y

An employee makes an hourly rate plus any tips they earn. This tip employee made a total of $400 by working 28 hours last week. If $253 of their total earnings was their tips, what is their hourly rate of pay?

Answers

To find the answer we must remove the tips amount from the total amount, and then divide what remains by the numbers of hours he worked. So we have: HourlyRate = (400 - 253) / 28 <=> HourlyRate = 147/28 <=> HourlyRate = $5.25
