1. SOCCER Suppose a youth soccer field has a
perimeter of 320 yards and its length measures 40
yards more than its width. Ms. Hughey asks her
players to determine the length and width of their
field. She gives them the following system of
equations to represent the situation. Use elimination to
solve the system to find the length and width of the
field.
2L + 2W=320
L - W = 40

Answers

Answer:

L = 100

W = 60

Step-by-step explanation:

2L + 2W = 320

-2L + 2W = -80

4W = 240

W = 60

L - W = 40

L - 60 = 40

L = 100

The price of a washing machine was decreased by 20% to £640.
What was the price before the decrease?

Answers

Answer:

£800

Step-by-step explanation:

Find 1% of the washing machine price using the percentage and the price of the washing machine after it decreased to help you.

100 - 20 = 80

80% = 640

1% = 640 ÷ 80 = 8

Now, since they asked the price before it decreased, they are asking for the full price.

100% = 8 x 100 = 800

Beth and Kayla are selling flower bulbs for a school fundraiser. Customers can buy packages of tulip bulbs and bags of daffodil bulbs. Beth sold 7 packages of tulip bulbs and 9 bags of daffodil bulbs for a total of $269. Kayla sold 7 packages of tulip bulbs and 2 bags of daffodil bulbs for a total of $136. Find the cost each of one package of tulip bulbs and one bag of daffodil bulbs.

Answers

Answer:

the cost each of one package of tulip bulbs and one bag of daffodil bulbs is $14 and $19 respectively

Step-by-step explanation:

The computation of the cost of each of one tulip package bulbs and one bag of daffodil bulbs is shown below:

Let us assume the tulip bulbs be x

And, the daffodil bulbs be y

According to the question

7x + 9y = $269.........(1)

7x + 2y = $136..........(2)

Now subtract equation 2 from equation 1

7y = $133

y = $19

Now put the value of y in any of the above equation

7x + 9($19) = $269

7x = $269 - $171

x = $14

Hence, the cost each of one package of tulip bulbs and one bag of daffodil bulbs is $14 and $19 respectively

You have a choice of two different Internet Service companies: AOL and Yahoo. One of AOL’s plans charges $19.99
for a month and a charge of $2.00 per hour. Yahoo’s similar plan offers service for only $14.99 a month and a charge
of $2.50 per hour. How many hours would you need to use the internet for the charges to be equal? What would the
monthly charge be?

Answers

First, you’re starting equation should look something like this:
19.99+2h= 14.99+2.50h
H equaling hours
You would then subtract 2h from 2.50h, so now you’re equation will look like this:
19.99=14.99+0.50h
Then, subtract 14.99 from 19.99. The equation should look like:
5=0.50h
Finally, divided 0.50h to 5 to get 10
10=h
You’re finally answer should be, It would take 10 hours for the Internet cost to be equal. The monthly charge would then be 39.99. You can find your answer by replacing h on either sides or your starting equation and insert 10.

If varies inversely as . It is known that = 10 when = 3, find the value of when = 5.

Answers

Answer:

y = 6

Step-by-step explanation:

If x varies inversely proportional as y.

[tex]x=\dfrac{k}{y}[/tex], k is constant of proportionality

or

k = xy

When x = 3 and y = 10

k = 3×10

k = 30

Put x = 5,

[tex]y=\dfrac{k}{x}\\\\y=\dfrac{30}{5}\\\\y=6[/tex]

So, the value of y is 6 when x is 5.
