Answer:

Sam had 80 dollars in his pocket. He was feeling generous, so he handed out equal amount of money to each of his friends. After he handed out the money, he had 53 dollars left. How much did Sam give out to each one of his friends?

Step-by-step explanation:

In this real-world problem, the money he had at the beginning resembles the 80 in the equation. The -3x is the money he gives out to each of his friends. The 53 on the right-hand side is the money he has left after he gives the money away.

Ugo [173]

Company A has a sales position with a yearly salary of $42,000. Company B has a similar sales position with a slary of $39,000 plus 1% conmission on yearly sales.

Let x be the amount of yearly sales

Company A has a sales position with a yearly salary of $42,000.

yearly salary = 42,000

Company B has a similar sales position with a salary of $39,000 plus 1% commission on yearly sales.

1% is 0.01

yearly salary = 39,000+ 0.01x

yearly sales is the salary at company A greater than the salary and conmission at company B

A > B

42000 > 39000+ 0.01x

We solve the inequality

39000+ 0.01x < 42000

Subtract 39000 on both sides

0.01x < 3000

divide by 0.01

x> 300,000

For yearly sales > $300,000, the salary at company A greater than the salary and commission at company B

19^2 + x^2 = 21^2

19^2 = 361

21^2= 441

361 + x^2 = 441

x^2 = 441-361 = 80

x = sqrt(80) = 8.944 round to nearest tenth = 8.9
