Answer:

18p + 6w

Step-by-step explanation:

I don't speak Spanish so here is some way I can explain it

No hablo español, así que aquí hay una forma de explicarlo.

using distribute property, get 2(8p) + 2(3w) = 18p + 6w

Answer:

[tex]16p + 6w[/tex]

STEP BY STEP

(8P+3W)2

=(8P+3W)(2)

=(8P)(2)+(3W)(2)

=16P+6W

Answer:

Step-by-step explanation:

Step one:

given data

First tree

the tree is 8cm tall

and 30cm from the vanishing point

Third  tree

let the tree be x cm tall

and 20cm from the vanishing point

Step two:

if 8cm tree will be 30cm at the vanishing point

then x cm tree will be 20cm at the vanishing point

cross multiply we have

x= (20*8)/30

x=160/30

x=5.3cm

The third tree is 5.3cm tall

Answer:

What the question? I'm confused.

Answer:

what?????

Step-by-step explanation:

Answer: I'm not sure If i'm right because I did this since 8th grade.

For number 7, I think it would be (the equation form)= 6 x  +  16

For number 8, I think it would be nothing because there is no solution.

Answer:

  60 hours

Step-by-step explanation:

We want Joanna's total savings to be ...

  bank account + gift + earnings = 1000

  300 +100 +10h = 1000

  10h = 600 . . . . subtract 400

  h = 60 . . . . . . . .divide by 10

Joanna needs to babysit for  60 hours to earn the money she needs.

Answer:

x=7

Step-by-step explanation:

Step 1: Put the variables and constants on the same side and change their signs so it'll look like this 5x-2x = 28 - 7, you always move the smaller number to either the left or right depending on its position in the problem.

Step 2: solve each side normally like this, 3x = 21

Step 3: to get x by itself divide 3 on both sides and you should get x=7

Here's a run through of the steps

5x+7=2x+28

   -7       -7(subtract 7 from both sides

5x=2x+28-7

-2x   -2x(subtract 2x from both sides)

5x-2x=28-7

3x=21

3x/3 = 21/3 (divide 3 from both sides)

x=7

Answer:

5/8x+1/2x-4=5

or, 5(2x-4)+8x= 5

or, 10x- 20+8x=5

or, 10x-8x= 20+5

or, 2x= 25

or,x= 25/2

:.x= 25/2

Step-by-step explanation:

first we have to make denominator then we can criss cross multiply. we can make in same point .if there is plus we can subtract and if there is front minus if we take it back it must be plus. then we can put same point then we can divide

The number of books that can be fit on a shelf is 1 meter long and will be 40.

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

Kaelyn is reading a book.

The book's thickness is 25 millimeters.

Then the number of the books that can be fit on a shelf is 1 meter long will be

Let x be the number of the books.

The thickness of the book in meters will be 0.025 m.

Then we have

0.025x = 1

         x = 1 / 0.025

         x = 40

Answer:

The area of given figure is: 179.3

Step-by-step explanation:

The figure consists of a rectangle and a semi-circle

The length of rectangle is 14 and width is 10.

The width of rectangle is also the diameter of the semi-circle.

So,

d = 10

[tex]r = \frac{d}{2} = \frac{10}{2} = 5[/tex]

Area of Semi-Circle:

[tex]C =\frac{ \pi r^2}{2}\\= \frac{3.14 * (5)^2}{2}\\=\frac{3.14*25}{2}\\=\frac{78.5}{2}\\= 39.25[/tex]

Area of Rectangle:

[tex]R = Length * Width\\R = 10*14\\R = 140[/tex]

The total area will be the sum of area of rectangle and the area of semi-circle

So,

[tex]Total\ Area = C + R\\= 39.25 + 140\\=179.25[/tex]

Rounding off to nearest tenth

The total area is: 179.3

Answer:

C

Step-by-step explanation

Answer:

C.)

Step-by-step explanation:

First, let's make it so that 6/8 and 4/5 have the same denominator.

Find the LCM: 40

8 ÷ 40 = 5

5 ÷ 40 = 8

Now that we have this info, let's convert the numerator to match the denominator.

4/5:

4 × 8 = 32

So... 4/5 = 32/40

6/8:

6 × 5 = 30

So... 6/8 = 30/40

Now let's add:

30/40 + 32/40

30 + 32 = 62

Therefore: 62/40

Now let's add those whole numbers: 5 + 4 = 9

Our answer: 9 62/40

Let's simplify: 10 22/40

Therefore, C is the correct answer.

Step-by-step explanation:

We want to represent the value of this number using expanded notation

Mathematically, that will be;

(3 * 100,000) + (0 * 10,000) + (4 * 1000) + (0 * 100) + (5 * 10) + (6 * 1)

= 300,000 + 0 + 4000 + 0 + 50 + 6
