(x - 3)(x + 9) = -27

Expand the brackets:

x^2 + 9x - 3x - 27 = -27

Simplify:

x^2 + 6x - 27 = -27

+ 27 to both sides

x^2 + 6x = 0

Factorise:

x(x + 6)

The solutions are x = 0, x = -6

Answer: If you would like to solve (x – 3)(x + 9) = –27, you can do this using the following steps:

(x – 3)(x + 9) = –27

x^2 + 9x - 3x - 27 = -27

x^2 + 6x - 27 + 27 = 0

x^2 + 6x = 0

x * (x + 6) = 0

1. x = 0

2. x = -6

The correct result would be x = 0.

Thats the correct definition

Answer:

first one take 1.5$ and the second one take 1.86$

Step-by-step explanation:

x + y = 3.36 --> the boys are splitting $3.36

x = 3y - .12 --> one boy received $.12 less than 3 times as much as the other

--> substitute the second equation for the x in the first equation

(3y - .12) + y = 3.36 --> combine like terms

4y - .12 = 3.36 --> add .12 to both sides of the equation

4y = 3.48 --> divide both sides by 4

y = .87

the other boy gets $0.87

substitute into x = 3y - 12

x = 3(.87) - .12

x = 2.61 - .12

x = 2.49

the first boy gets $2.49

Answer:

Haruka's final exam score in chemistry is 87

Step-by-step explanation:

Given mean of data set = 84

given score

Astronomy 72

Biology 85

Physics 92

Chemistry ?

we have to find score of chemistry

let the score of chemistry be x

we know that mean is sum of data set divided by no of terms in data set

mean = sum of data set /no of terms in data set

number of terms in our problem is 4 (Astronomy,Biology,Physics,Chemistry)

sum of set

72+85+92+x = 249+ x

as mean is 84,

hence

84 =  (249+ x)/4

=> 84*4 = 249 + x

=> 336 = 249 + x

=> 336 - 249 = x

=> x = 87

Thus, Haruka's final exam score in chemistry is 87.

Answer:

So this is called scientific notation, you can write as

7.16e-5 not saying euler's number.

To put in standard you move the decimal point in the direction of the sign and that many times. So in this case the direction of the sign is - because -5 so we move the decimal to the left, in this case we do it 5 times. So we move it five times 0.000716 is what you get

Answer:

0.0000716

Step-by-step explanation:

7.16 x 10^-5 = 7.16*0.00001 = 0.0000716

Step-by-step explanation:

Answer:

7(14)-11=87

2(14)-3=25

5(14)-2=68

Step-by-step explanation:

Ight Homie, lemme help you out.

To start, add (7x-11) + (2x-3) + (5x-2)

That should get you (14x-16)

Then set up the equation

14x-16=180

180 is the sum of the triangle angles. (if i said that right)

Then solve for x

14x-16=180

     +16   +16

14x=196                Divide

((14x)/14)=196/14

x should equal 14.

Then replace x with 14

7(14)-11=87

2(14)-3=25

5(14)-2=68

I hope this helps. Stay safe Homie!

Answer:

$6,300

Step-by-step explanation:

Step 1

Find the Cost Price of the books

A trader purchased 1,000 books at the rate of $5.40 per book

This is calculated as:

If 1 book = $5.40

1000 books = ???

We cross multiply

1000 books × $5.40

= $5,400

He bought 1000 books for $5,400

His total cost price = Transportation + Cost of books

Transportation = $200

Cost price = $5,400 + $200

= $5,600

Step 2

Find the profit he made from the sale of the books

Percentage profit = Profit / Cost price × 100

Percentage profit = 12.5%

Cost price = $5,600

We have :

12.5 = Profit/ $5,600 × 100

12.5 = (100 × Profit)/ $5,600

Cross multiply

12.5 × $5,600 = 100 × Profit

Divide both sides by 100

(12.5 × $5,600) ÷ 100 = Profit

Profit = $700.

Step 3

Find the selling price

The Formula to calculate Selling Price is given as:

Selling price = Cost Price + Profit

Selling price = $5,600 + $700

Selling price = $6,300

Step-by-step explanation:

7x-1+2x-1=7

9x=9

x=1

Answer:

x=1

Step-by-step explanation:

RS + ST = RT

7x-1 + 2x-1 = 7

Combine like terms

9x-2 = 7

Add 2 to each side

9x-2+2 = 7+2

9x= 9

Divide by 9

9x/9 = 9/9

x = 1

Answer:

y=-6-x/2

Step-by-step explanation:

Answer:

y = -x/2 -3

Step-by-step explanation:

So there are LOTS of ways you can choose to do this, but this is how i do it:

I like to move all the x to one side first, so:

2y = -x -6

Then we have to divide everything by 2 to get y on its own:

y = -x/2 -3

*you can divide first too if you want, i find that this keeps it nice and simple though

Hope this helped : )

Step-by-step explanation:

Answer:

48 students in science

Step-by-step explanation:

Let r = students in robots club

s = students in science club

r+s = 84

s = r+12

Substitute the second equation into the first

r+(r+12) = 84

Combine like terms

2r+12 = 84

Subtract 12 from each side

2r = 84-12

2r = 72

Divide by 2

r = 72/2 = 36

We need to find s

s = r+12

s = 36+12

s = 48

There are 48 students in the science club

Answer:

x=-5/2

Step-by-step explanation:

4 x^2 +20 x +25 = 0

x^2+5x=-25/4
