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:

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

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:

12 nickels, 9 quarters, 15 dimes

Step-by-step explanation:

Let's call the number of nickels n, the number of dimes d, and the number of quarters q. Now, we can set up the following equations:

n+d+q=36

q=n-3

d=q+6

Now, we can do some substitution:

d=(n-3)+6=n+3

Plugging this into the first equation, you get:

n+(n+3)+(n-3)=36

3n=36

n=12

There are twelve nickels, meaning that there are 9 quarters and 15 dimes. Hope this helps!

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:

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:

∠ BOJ and ∠BOE

Step-by-step explanation:

A central angle is an angle whose vertex is at the centre of the circle.

The 2 sides of the angle are radii from the opposite ends of an arc.

∠ BOJ and ∠ BOE are therefore central angles

Answer:

Option (b)

Step-by-step explanation:

Let the points represented by the given table lie on a line.

And the equation of the line is,

y = mx + b

Where m = slope of the line

b = y-intercept

Let the points lying on the line are (0, -2) and (3, -3)

Slope of the line 'm' = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

m = [tex]\frac{-2-(-3)}{0-3}[/tex]

m = [tex]\frac{-2+3}{0-3}[/tex]

m = -[tex]\frac{1}{3}[/tex]

y-intercept 'b' = (-2)

Equation of the line is,

y = [tex]-\frac{1}{3}x-2[/tex]

This equation matches with equation given in option (b).

Option (b) will be the answer.

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

Answer:

P=1440

Step-by-step explanation:

"P is 90 more than Q."

P=Q+90

"20% of P is equal to 1/3 of Q."

1/5(P)=(1/3)Q

From the first equation, we have that P=Q+90.

Thus, we can substitute any P's for Q+90's!

The second equation becomes 1/5(Q+90)=(1/3)Q

Distribute the 1/5 and 1/3 to get (1/5)Q+180=(1/3)Q

Subtract 1/5 Q from both sides.

You should get 180= (2/15)Q

Multiply both sides by 15/2 to get 1350=Q.

Given Q, we can easily solve for P.

Remember the first equation- P=Q+90

Then substitute in 1350 for Q.

So we have P=1350+90

Finally, we have P=1440

(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.
