Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together so their kite can fly higher. Wr

torisob [31]

Question:

Jordyn, Teri, and Morgan are going to have a kite-flying contest. Jordyn and Teri each have one roll of kite string. They also each have 45 yards of extra string. Morgan has three rolls of kite string plus 10 yards of extra string. All the rolls of string are the same length. The girls want to see who can fly their kite the highest.

Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together, so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.

Answer:

$y=x +45$

$y = 45 + x$

Step-by-step explanation:

From the complete question, we have:

<u>Jordyn & Teri</u>

<u></u> $Rolls = 1$ <u></u>

<u></u> $Extra = 45\ yd$ <u></u>

<u></u>

<u>Morgan</u>

<u></u> $Rolls = 3$ <u></u>

$Extra= 10\ yd$

Required

Expression for Jordyn and Morgan

Let the total kite by Jordyn and Teri be represented with y

This is calculated as:

$y = Rolls + Extra\ Yard$

This gives:

$y = 1\ roll + 45yd$

1 roll is represented with x.

So:

$y=1x +45$

$y=x +45$

This can be rewritten as:

$y = 45 + x$

Miss Guydan and her friend Alyssa are collecting food for the local food bank. Their goal is to collect 2100 pounds of food. The

Serjik [45]

Answer: Required equation: 400+25x = 2100

Variable: x = Number of days to donate 2100 pounds.

Step-by-step explanation:

Let x = Number of days.

y = Total pounds of food donated in x days.

Given: Initial amount of food = 400 pounds

Pounds of food donated per day = 25

Total food = Initial amount of food + (Pounds of food donated per day ) (Number of days)

y = 400+25x

Their goal is to collect 2100 pounds.

2100 = 400+25x [Substitute y= 2100]

Required equation: 400+25x = 2100

Variable: x = Number of days.
