Nastasia [14]

100% of her middle school class = 56
200% of her middle school class = 112 (56 x 2)
25% of her middle school class = 14 (56/4)
225% of her middle school class = 126 (112 + 14)

There are 126 students in her high school class.

Lelechka [254]

5x+2y = 5.84 is the equation for maddi.

2x+ 8y =10.40 is the equation for stephen.

set them equal and then cancel them out! if you do that you can plug it into the part 2 equation which is

2x+4y+z=4.07

Shelby loves to knit scarves. Normally, it takes her 15 minutes to knit 5 inches of a scarf. She plans to make a scarf that is 3

MariettaO [177]

Answer:

90 minutes

Step-by-step explanation:

let x=amount of time it would take for Shelby to knit the scarf

$\frac{15}{5} =\frac{x}{30}$

cross multiply

15*30=5x

450=5x

450/5=x

x=90

It would take Shelby 90 minutes to knit a scarf that is 30 inches long.

The manager of a restaurant found that the cost to produce 150 cups of coffee is $ 20.00, while the cost to produce 400 cups i

34kurt

Answer: Our required linear equation would be $10y-x=50$

Step-by-step explanation:

Since we have given that

Number of cups = 150

Cost = $20

Number of cups = 400

Cost = $45

Let x be the number of cups, y be the cost .

We will use "Equation of line using Two point slope":

$y-20=\dfrac{45-20}{400-150}(x-150)\\\\y-20=\dfrac{25}{250}(x-150)\\\\10(y-20)=(x-150)\\\\10y-200=x-150\\\\10y-x=-150+200\\\\10y-x=50$

Hence, our required linear equation would be $10y-x=50$
