Answer:

One bag of chips costs $1.10

One can of soda costs $0.50

Step-by-step explanation:

1. Create a system of equations (b = bags of chips | s = soda)

10b + 8b = 15

5b + 5s = 8

2. Use the Elimination method by multiplying 5b+5s=8 by -2

10b + 8b = 15

-2(5b + 5s = 8)

=

10b + 8b = 15

- 10b - 10s = -16

(10b and -10b will cancel out, so you will only have s left)

=

-2s = -1

Divide by 2

Soda = 1/2, or $0.50

3. Plug in S (0.50) into an equation above and get B by itself

5b + 5(0.50) = 8

=

5b + 2.5 = 8

    - 2.5    -2.5

5b = 5.5

Bag of Chips = $1.10

Answer:

-9

Step-by-step explanation:

5x-3x=-10-8

2x= -18

x=-18/2

= -9

Solution of the expression is,

⇒ x = - 9

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Equation is,

⇒ 5x + 8 - 3x = -10

Now, We can simplify as;

⇒ 5x + 8 - 3x = -10

⇒ 2x = - 10 - 8

⇒ 2x = - 18

⇒ x = - 18/2

⇒ x = - 9

Thus, Solution of the expression is,

⇒ x = - 9

Answer:

a = 0.3

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

(5.3a - 0.8) - (1.6 - 4.7a) = 2a - (a - 0.3)

Step 2: Solve for a

Step 3: Check

Plug in a to verify it's a solution.

Here we see that 0.6 does indeed equal 0.6.

∴ a = 0.3 is a solution of the equation.

Answer:

1. ∠A = ∠W

2. ∠B = ∠X

3. ∠C = ∠Y

4. ∠D = ∠Z

Step-by-step explanation:

This is actually a lot more simple than you think!

In order to solve this you must be able to distinguish both of the points from each figure shown in the picture!

In this case, we can see that Figure WXYZ is faced in a upright manner!

While Figure ABCD is in a regular position!

What you want to do is turn either Figure ABCD or WXYZ in to the same position and you will see that the shape, points, and position will be same!

For example:

(This is two separate lines that are in different positions)

A

|

B

C ------ D

If you are to change either in the same position, in this case I'll change

line AB to the same position as CD:

A ------ B

C ------ D

You can see that which points will be corresponding to each other!

(Corresponding means two that are similar or same to each other in characteristics)

So the answer to the example would be:

Point A = Point C

&

Point B = Point D

Back to the original problem, it works the same way:

If you turn figure WXYZ in the same position as ABCD, you will get the answers:

1. ∠A = ∠W (Answer choice: B)

2  ∠B = ∠X (Answer choice: C)

3. ∠C = ∠Y (Answer choice: D)

4. ∠D = ∠Z (Answer choice: A)

You can also see this when they say:

'Figure ABCD is similar to Figure WXYZ'

In means of angles it would look like:

(Figure) ABCD = (Figure) WXYZ

And if you were to separate each letter with the one it corresponds to on the other side, you will see that you will get:

A = W

B = X

C = Y

D = Z

Answer:

43

Step-by-step explanation:

3x + 10 = 5x - 12

       10 = 2x - 12

      22 = 2x

        x = 11

check:

33 + 10 = 55 - 12

43 = 43

correct

x = 11 so bring this into 3x + 10

we get 43

Answer:

short story has 32 pgs

novel has 416 pgs

Step-by-step explanation:

a novel (N) has 13 times as many pages as a short story (x) so, N = 13X

total pages is the equation N + x = 448

plug the equation for N into this

13x + x = 448, combine like terms

14x = 448, divide both sides by 14

x = 32. so now we know that the short story has 32 pages. subtract that from 448. and the novel has 416 pages.

There are 32 pages in the short story and 416 pages in the novel.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

Let x be the number of pages in the short story.

We know that the novel has 13 times as many pages as the short story, so the number of pages in the novel is 13x.

The combined number of pages in the books is the sum of the number of pages in the short story and the number of pages in the novel, which is x + 13x = 14x = 448 pages.

So the number of pages in the short story is x = 32 pages.

And the number of pages in the novel is 13x = 13 × 32 = 416 pages.

Answer:

1.5 meters per second

Step-by-step explanation:

30 meters in 20 seconds. U need to "separate" the 30 seconds into 20 parts so u have to divide:

30/20 = 1.5

Answer: 1.5 meters

Step-by-step explanation:

To find how many meters in 1 second we need to make a unit. We'll use fractions in this case...

30 meters     ÷ 20               1.5 meters

--------------                    =       -----------------

20 seconds   ÷   20              1 second

This is a fancy was of saying 1.5 meters per 1 second.
