You work at a public golf course. You have a budget of $300 for supplies for the month. The golf course can buy golf balls at a price of $0.80 each. Write an inequality that states the number of golf balls you can buy at this price and still have $200 left in your budget for other items.

(please give nice clear real answers otherwise you will be reported, thank you soo much!)

200 + 0.8x = 300

200 + 0.8x = 300

- 200 - 200

0.8x = 100

0.8 0.8

x = 125

Step-by-step explanation:

You have a TOTAL of 300 and want to spend it on the golf course. 200 MUST REMAIN in order to purchase other items. Golf balls are at a price of 0.8 EACH. The amount of golf balls that can be purchased is unknown so we can place x as the number of balls purchased for 0.8 each. (I bolded some words because it can help to how to set up an equation and where they should go. :D) I hope my explanation is clear enough for you to understand. I also solved the inequality above ^^^! I hope this helps!

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
