Step-by-step explanation:

Step one:

given data

let the manufacturing cost of the video game be x

25% of x

=25/100*x

=0.25x

the new price of the video game will be

=0.25x+x

=$1.25x

cost of shipping is given as $1.5

let the total cost of producing a video game be y

The expression for the total cost of one video game is given as

Answer:

x=10

Step-by-step explanation:

2x-12 = 18

    +12  +12

2x=20

20/2 = 10

Answer:

24

Step-by-step explanation:

Original equation:

2x - 12 = ?

We know x = 18

So, just plug the value into the equation

2(18) - 12

Multiply 2 by 18

36

Subtract 12 from 36

The answer is 24

Answer:

(2,0)

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

2x+y=4; x−y=2

Step: Solve 2x+y = 4 for y:

2x + y + −2x = 4 + −2x (Add -2x to both sides)

y = −2x+4

Step: Substitute −2x+4 for y in x−y=2:

x − y=2

x−(−2x + 4)=2

3x − 4=2(Simplify both sides of the equation)

3x − 4 + 4 = 2+4 (Add 4 to both sides)

3x =6

(Divide both sides by 3)

x=2

Step: Substitute2forxiny=−2x+4:

y= −2x + 4

y=(−2)(2) + 4

y=0 (Simplify both sides of the equation)

Answer:

x=2 and y=0

Answer:

15/4- 4 1/3

15/4-13/3

45/12-52/12

-7/12

Step-by-step explanation:

Answer:

You are not dumb

Step-by-step explanation:

15/4 - 4 1/3 make the 4 1/3 a improper fraction

15/4 - 13/3  find common denominator of 12

45/12-52/12  since 4 goes into 12 3 times, times the top by 3 to get 45. The second one-3 goes into 12 4 times, so times the top by 4 to get 52.

45/12-52/12= 45-52= -7 put the -7 over the 12

-7/12 that is your answer

Answer:

Correct me If I am wrong :)

Step-by-step explanation:

Answer:

Option C is the correct option.

Step-by-step explanation:

A set of equations is given below:

Equation H: y = -x + 2

Equation J: y = 3x - 4

We need to determine the step to solve the equations.

We can place value of y from Equation H into Equation J

i.e

-x+2=3x-4

So, Option C is the correct option.

Answer:

8x^2+38x+45 so B

Step-by-step explanation:

i got it right on the test

The required equation of the function that represents the area of the porch is A(x) = 8x² + 38x + 45. Option D is correct.

Given that,
Dan is tiling his rectangular, concrete porch with square, porcelain tiles. The length of the porch is represented by the function l(x)=4x+9, where x is the side length, in feet, of each tile. The width of the porch is represented by the function w(x)=2x+5.

The surface area of any shape is the area of the shape that is faced or the surface area is the amount of area covering the exterior of a 3D shape.

Here,
Length of the porch = 4x + 9
Width of the porch = 2x + 5
area of the porch A(x) = (4x + 9) (2x + 5 )
                                     = 8x² + 20x + 18x + 45
                                     = 8x ² + 38x + 45

Thus, the required equation of the function that represents the area of the porch is A(x) = 8x² + 38x + 45. Option D is correct.

Answer:

Seth saved $90.

Step-by-step explanation:

1.Find out how much would be spent without buying the movie pass.

Multiply the amount of money that one would spend for each movie, by the number of movies one saw.

8 * 30 = 240

2.Find out the amount that was actually spent

Multiply the amount that was actually spent on each movie, by the number of movies that were seen. Then add the additional cost of the pass.

(4 * 30) + 30

= 120 + 30

= 150

3. Find the difference between the two values.

Subtract the amount that one was supposed to spend by the amount one did spend.

240 - 150

= 90

Answer:

Step-by-step explanation:

The price per ounce for the 8-ounce jar is ...

  price/ounces = $8.95/8 = $1.11875 ≈ $1.12 . . . per ounce

The price per ounce for the 10-ounce jar is ...

  $12.00/10 = $1.20 . . . per ounce

The 8-ounce jar has a lower unit price, so may be better to buy.*

__

The difference in unit prices is ...

  $1.20 -1.12 = $0.08

_____

* If you need at most 10 ounces, but more than 8, the 10-ounce jar will have a lower total cost for the amount needed. The "better buy" depends on the context.

Answer:

105

Step-by-step explanation:

First, you are going to convert dollars to cents. Since there are 100 cents in a dollar, multiple $20 by 100. Now you should have 2,000 cents. Now all you have to do is divide by 19, the cost of the stamps, and you should get 105.26. Because you can't by part of a stamp your answer would be 105.

The compound inequality that represent the situation is 2(x + 7) > 6 and 2(x + 7) ≤ -3.

Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.

Compound inequality is an inequality that combines two simple inequalities.

Therefore, let's represent twice the sum of a number and 7 is more than 6 or at most -3 with compound inequality as follows:

Answer:

Choice D

Step-by-step explanation:

When you find the unit price it will be easier to eliminate the other choices and to find the unit price I found the easiest numbers to work with, so if we do $5 divided by 2 lbs it'll give us $2.5 and that's our unit price. Then for the graphs we are left with choices C and D. So all we have to do is see which one has the line passing through point (2,5) which stands for 2 oranges and $5.

Answer:

10 : 12 is equivalent to 5 : 6 and 20 : 24.

Step-by-step explanation:

You can divide and multiply the ratio by 2 to get an equivalent ratio.

The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24 Therefore, option (C) will be correct.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given ratio, 10:12.

Divide numerator and denominator by 2

(10/2):(12/2) = 5:6.

Multiply the numerator and denominator by 2

(10×2);(12×2) = 20:24

Hence "The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24".
