Enrique is 5 years younger than his sister, Josefina. Josefina is 15. How old is Enrique?Let E = Enrique's age.

Answers

Answer 1

Answer: Hi there!

In order to solve this problem, we would create the math equation sentence

15 - 5 = e

Then, of course, we do the math.

15 - 5 = 10

And the answer is -

E = 10

I hope this helps you!

A bookstore orders 200 books. The books are packaged in boxes that hold 24 books each. All the boxes the bookstore receives are full, except one. How many boxes does the bookstore recieve??

Answers

First we will divide to se how many boxes there will be.

200 ÷ 24 = 8.333......

So there would be 9 boxes cause there is 1 box that is not FULL.

Next we will multiply.

24 × 8 = 192

Subtract:-

200 - 192 = 8

So there are 9 boxes. The 9th box has 8 books.

suppose the equation for line A is given by 2x-5y=15, if line A and B are parallel and the point (-10,3) lies on line B, then write the equation in slope intercept for line b.

Answers

Answer:

y=2/5x + 7

Step-by-step explanation:

First, you have to rewrite 2x-5y=15 to slop intercept form.

To do that you have to first subtract 2x from both side to cancel it out.

2x- 2x-5y= 15 -2x.

-5y= -2x+15

Next, you divide 5 on both side to leave the y by itself.

y= -2x/-5 + 15/-5

Simplify

y= 2/5x + (-3) 2/5 is our slope

Now that we found the slope, we need to the y-intercept of line b

y=2/5x + b

To find the y-intercept, we substitue x and y with the coordinates (-10,3)

3= 2/5(-10) +b

Now we just solve for b

3= -4 +b

3-(-4) = b

7=b

Now we have identified that 7 is the y intercept

The full equation is y= 2/5x +7

The dimensions of a large room are double the dimensions of a small room.Both rooms are rectangular prisms. The volume of the small room is 10 cubic
metres.
What is the volume of the large room?

Answers

The volume would be 80 cubic metres. Think about the three different dimensions for the small room as x,y and z. Therefore the volume is x*y*z= xyz. Now for the bigger room, the dimensions would be 2x,2y and 2z. Therefore, its volume would be 2x*2y*2z= 8xyz. Since xyz (volume of the smaller room)= 10 cubic metres, the bigger room's volume will be 8*10= 80 cubic metres.

Determine the slope and the y-intercept.
y = 5x + 6

Answers

When that equation is graphed, it produces a straiught line. The slope
of the line is 5, and the line intersects the y-axis at y=6.

All function of type: y = ax + b

a = slope b = intersept

So:

slope = 5
intersept = 6

Write -2x 2(-5x 2 +4x 3) in standard form

Answers

If you would like to write -2x^2 * (-5x^2 + 4x^3) in standard form, you can do this like this:

Writing the polynomial in standard form means that you have to write the terms by descending degree:
-2x^2 * (-5x^2 + 4x^3) = 2 * 5 * x^2 * x^2 - 2 * 4 * x^2 * x^3 = 10 * x^4 - 8 * x^5 = - 8x^5 + 10x^4

The correct result would be - 8x^5 + 10x^4.

The expression $-2x^2(-5x^2 + 4x^3)$ in standard form is $10x^4 - 8x^5$ .
