Jessie is building a doghouse. For one side of the roof, she needs a board that is 7 3/4 feet long. She has a board that measure 9 1/12 feet. How much of the length does she need to cut from the board? Show your work and simply the fraction.

Answers

Answer 1

Answer: 9 1/12 ft = 109/12
7 3/4 = 31/4
You need to give them the same denominator, so you'll need to multiply the top and bottom of 31/4 by three
109/12 - ((31*3)/(4*3))=x
109/12 - 93/12 = x
(109-93)/12 = x
16/12 = x
(16/4)/(12/4) = x
4/3 = x
4/3 = 1 1/3
Jessie needs to cut 1 1/3 feet off the board.

A pencil at a stationery store costs $1, and a pen costs $1.50. Shawn spent $12 at the store. He bought a total of 9 items. Which system of equations can be used to find the number of pencils (x) and pens (y) he bought?

Answers

x= 3 pencils 3+6=9 items
y= 6 pens
So, Shawn bought 3 pencils and 6 pens. 1 pen equals 1.50 and a pencil only costs a dollar and he spent 12 dollars so now if he bought 6 pens and 3 pencils that would equal 12.

9x=£9. 9y=13.50. It has to be an even number of y or you will get a decimal and 12 is not a decimal. 7x+2y=£10 5x+4y=£11. 3x+6y=£12 The answer is three pencils and 6 pens.

Joey has $254 to spend at the video game store. He was able to buy 9 video games and had $29 left. How much did each game cost? (Please help :()

Answers

If he had $254 to spend, and at the end (after spending) he was left with $29, then that means he spent $225 on video games. That's because we're taking away what he has now from what he had originally to spend, which leaves us with how much he spent on games in total.

So, if we know that he spent $225 on 9 video games, we can work out how much each game costs by dividing the amount he spent ($225) by the number of games (9) to give us the final answer:

$225 ÷ 9 = $25

He spent $25 on each game. Hope that helped! :)

Answer: $25

First we figure out how
much money Joey spent:
254 - 29 = 225

now we divide that by 9
225 / 9 = 25
