Answers

Answer 1

Answer:

the answer is A

Step-by-step explanation:

5x + 78 + 47= 180

solve for x

x=11

Answer 2

Answer: A) 11

Step-by-step explanation:

there are 180 degrees in a triangle. so, i added 47 and 78 together. that got me 125. i subtracted that from 180, in order to find the remaining angle.

it was 55 degrees, so i divided 55 by 5 in order to see what that was. whatever number that is was going to be x. it turned out to be 11.

hope this helps! xoxo

Mr Lee has a family of 6 people and Mrs Scarlett has a family of 4. They were given 15 kg of chocolate
when they visited a chocolate factory for work. If they decide to share it so that each family
member gets an equal amount, determine the required ratio and hence calculate how much
chocolate Mr Lee and Mrs Scarlett will each take home to their families.

Answers

Answer:

Mr Lee gets 9kg

Mrs Scarlett gets 6kg

Step-by-step explanation:

First, we have 15kg of chocolate and a total of 6 + 4 = 10 people.

We want to divide the 15kg of chocolate evenly between these 10 people, then we just need to do the quotient

15kg/10 = 1.5kg

This means that each person gets 1.5 kg of chocolate.

Now, Mr. Lee has a family of 6 people, and each one of these 6 people got 1.5 kg of chocolate, then the total amount of chocolate that Mr. Lee will bring home is 6 times 1.5kg:

6*1.5kg = 9kg

And Mrs Scarlett will get the remaining, that is:

15kg - 9kg = 6kg

Mrs Scarlett will get 6kg of chocolate.

Step-by-step explanation:

Answer:

Linear is that y=ax

And a=slope=(y-y)/(x-x)

a=(3-1)/(1-0)=2/1=2

If it is linear then take point A(3,10) and replace it in the equation y=2x

Then 10 is not equal to 2(3) which is 6

Then the answer is nonlinear function

Given:

The cost of the T.V. for Colin = £ 800.

The rate of depreciation per year = 4%

Time period = 3 years

To find:

How much will it be worth in 3 years? Give your answer to the nearest penny where appropriate.

Solution:

To solve the above-given problem, we will use the following formula:

where

A = the final value after depreciation

P = the present value

R = rate of depreciation

n = time period

Now, on substituting the given values in the formula, we get

we will round the above answer to its nearest penny where appropriate

≈ £ 708

Thus, the worth of the t.v. in 3 years will be £ 708.

are there?

Answers

Answer:

There are 12 goats and 2 geese.

Step-by-step explanation:

X = geese; Y = goats

Geese have 2 legs each. Goats have 4 legs each.

2x + 4y = 52

There are 14 animals

x + y = 14

x = 14 - y

(replacement)

2(14 - y) + 4y = 52

(simplify)

28 - 2y + 4y = 52

28 + 2y = 52

2y = 24

y = 12

14 - 12 = 2

x = 2

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.

Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining. Jorges work is shown below.Let x = the number of games played.Equation: 8.25 minus 0.25 x = 9.75 minus 0.75 x. Step 1: negative 1.50 minus 0.25 x = negative 0.75 x. Step 2: negative 1.50 = 0.50 x.
