Answer:

<u>y=(-5/3x)+5</u>

Step-by-step explanation:

so you want to isolate the variable of y.

5x+3y=15

5x+3y-5x=15-5x

3y=-5x+15

3y/3=(-5x+15)/3

y=(-5/3x)+5

Eddie bought 27 2/5 inches of wire for a home improvement project. How many 12 inches sections can he make from it?
goblinko [34]
Simply divide your wire by 12 and cut off the excess (as it cannot make a full 12-inch section).

27\frac{2}{5}÷12=2\frac{17}{60}

So you have two 12-inch sections and an additional 3.4-inch section.

A girl scout was selling boxes of cookies. In a month, she sold both boxes of chocolate chip cookies ($1.25 each) and boxes of p
Katena32 [7]

Answer:

Number of plain cookie boxes sold = 785 boxes

Step-by-step explanation:

Given: Cost of a chocolate chip cookie box = $1.25

Cost of a plain cookie box = $0.75

Total number of boxes sold = 1585

Total cost of the sold boxes = $1588.75

Let, number of plain cookie boxes sold = x

Number of chocolate chip cookie boxes sold = 1585 - x

So,

Total cost = total cost of the sold plain cookie boxes + total cost of the sold chocolate chip cookie boxes

$1588.75 = x ($0.75) + (1585 - x) ($1.25)

1588.75 = 0.75 x + 1981.25 - 1.25 x

0.5 x = 392.5

Therefore,

<u>Number of plain cookie boxes sold: x = 392.5 ÷ 0.5 = 785 boxes</u>

Wittaler [7]

The price of the turkey based on the percentage given is $15.81.

<h3>How to illustrate the information?</h3>

It was stated that the cost is $15.50 but that there was a 2% increment in price.

Therefore, the new price will be:

= $15.50 + (2% × $15.50)

= $15.50 + $0.31

= $15.81
