Add the equations together will get you:

4x=0

Divide the 0 by 4 to get the x alone will get you

x=0

Answer:

There's one solution

(0,5)

Step-by-step explanation:

There's one solution

We can tell this is true because of the 3x in the second on and just hte x in the first. If you look closely you'll see the coefficents for the x values is the only difference between the two.

Let's now solve

We need to get a positive variable by itself

let's take x+y=5 and solve for y

x-5= -y

y= -x+5

We can then plug this y value into the other equation

3x-(-x+5)= -5

3x+x-5= -5

4x= 0

x=0

Let's then plug this value in for x into any of the beginning equations

0+y=5

y=5

In a holiday resort, the ratio of men to women is 5:6 and the ratio of
women to children is 4:7. There are 200 men staying at the resort. How
many children are there?​

Answers

Answer:

Men: 5 : 3 = 20 : 12

Women: 7 : 4 = 21 : 12

So for every 12 children there are 20 men to 21 women.

Neither men nor women compose more than half of the concert population

There are 200 men staying at the resort. Then the number of children in the resort will be 292.

What are ratio and proportion?

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

In a holiday resort, the ratio of men to women is 5:6 and the ratio of women to children is 4:7.

There are 200 men staying at the resort.

Then the number of women in the resort will be

Women / 200 = 5 / 6

Women = 500 / 3

Then the number of children in the resort will be

(500/3)  / children = 4/7

                children = 291.67

                children ≈ 292

find the slope of the line

Answers

Answer:

Slope = 4

Step-by-step explanation:

The slop of the line is going to be rise over run.

So take where it the y value is 20 as [tex]y_1[/tex], and where it hits about 32 as value [tex]y_2[/tex].

You have you x value when y1 as 5 and x value at yw as 8.

So what you will do here is

[tex]\frac{32-20}{8-5}[/tex]

[tex]\frac{12}{3} = 4[/tex]

So your slope is 4.

Solve for x

Answers

Answer:

x = -3

Step-by-step explanation:

To answer this question, you should first remember that the inside angles of a triangle will always add up to 180 degrees. Therefore, we can make an equation and solve it form there:

55 + 54 + (x + 74) = 180

We add like terms:

109 + (x + 74) = 180

Continue adding like terms:

183 + x = 180

Next, we dubtract to siolate the "x" variable:

x = -3

Hope this helps :)

x=-3

Step-by-step explanation:

To start off, you're going to want to know and understand that all the angles of triangle equal 180 degrees.

Now that we know a triangle equals 180 degrees, lets make an equation. This is equation can be 55+54+74+x=180.

Now, lets combine the like terms in the equation. The equation now becomes 183+x=180.

From here, we subtract 180 from both sides, which would get us x=-3.

To double check that this is correct and that it works, you can plug in the -3 where the x would be.

I hope this helped!! Let me know if you have any further questions.

Hi! Could you help me me out and solve these two problems? "eight less than the product of seven and xxx", and "the sum of six and the product of three and d". Thank you!

Answers

Given:

The given statement are:

a. Eight less than the product of seven and x.

b. The sum of six and the product of three and d.

To find:

The expression for the given statements.

Solution:

a.

Product of 7 and x is 7×x = 7x.

Eight less than the product of seven and x is 7x - 8.

Therefore, the required expression for the statement "Eight less than the product of seven and x" is 7x-8.

b.

Product of 3 and d is 3×d = 3d.

The sum of six and the product of three and d is 6+3d.

Therefore, the required expression for the statement "The sum of six and the product of three and d" is 6+3d.

A rectangles base is 2in. Shorter than twice its height. The rectangles area is 40in^2. Find it's dimensions.

Answers

Answer:

5 in by 8 in

Step-by-step explanation:

Given that :

Area, A of rectangle = 40 in²

Let

height = x

Base = 2x - 2

Area of rectangle = L * B

40 = x * (2x - 2)

40 = 2x² - 2x

2x² - 2x - 40 = 0

x² - x - 20 = 0

x² - 5x + 4x - 20 =0

x(x - 5) +4(x - 5) = 0

x - 5 = 0 or

x + 4 = 0

x = 5 or x = - 4

X cannot be negative

X = 5

Height = 5

Base = 2*5 - 2 = 8

You often go to school by bus. You have two bus systems you could take. City Bus offers a monthly pass that costs $15 and then you pay $1 per ride. Campus Transport simply charges $2.50 per ride and does not require a monthly pass. After how many rides will the total costs of the two options be the same? Write a system of equations in order to solve this problem.

Answers

Answer:

For City Bus you will need to ride 10 times for 2 months, and for Campus Transport you need to ride 16 times.

Step-by-step explanation:

$2.50 x 2 = $5.00 so you know that the number of rides needs to even in order to have a whole number. This is because there is no way the City Bus cost will ever have cents.

$2.50 x 16 = $40.00

$15 x 2 = $30

$1 x 10 = $10

$30 + $10 = $40

So (15 x 2) + (10 x 1) = 16 x 2.50

Anna opened a savings account and deposited $300.00 as principal. The account earns 1%
interest, compounded annually. What is the balance after 2 years?

Answers

Answer:

$6

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1%/100 = 0.01 per year,

then, solving our equation

I = 300 × 0.01 × 2 = 6

I = $ 6.00

The simple interest accumulated

on a principal of $ 300.00

at a rate of 1% per year

for 2 years is $ 6.00.

Times 300 by the 1%, in this case 0.01. Then add that amount to 300. Hope that helps.

A clothing manufacturer produces 120 garments per hour, of which 5 are damaged. How many garments without damage would the manufacture except to produce in 8 hours?

Answers

Answer:

Step-by-step explanation:

First we have to found all the clothes that the manufacturer produces in 8 hours,

As given    120 clothes = produce in 1 hour

                  X clothes  = produce in 8 hour

By cross multiplication, we get

X= 120*8

X= 960  total clothes produced in 8 hours

As also given that in each hour 5 clothes damaged ,so we can write as

 5 clothes = damaged in 1 hour

Y clothes = Damaged in 8 hour

By cross multiplication we get

Y=  40 clothes damaged in 8 hour

So the total clothes that manufacturer produce with out damage clothe will be ,

Total normal clothes = X-Y   = 960 - 40  = 920 clothes
