A store marks up a laptop 150% from its original price of $299. There is a sale for 25% off all items in the store. What is the sale price for the computer?

Answer:

y=27

Step-by-step explanation:

3y+53=7y-55

step 1 add 55 to each side

3y+108=7y

step 2 subtract 3y from each side

108=4y

step 3 divide each side by 4

Answer:

The basketball game sold 439  adult tickets and  858 student tickets.

Step-by-step explanation:

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is, in the systems of equations, one must look for the values ​​of the unknowns, with which when replacing, they must give the solution proposed in both equations.

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,047  was collected on the sale of 1,291 tickets.

With "x" the number of adult tickets sold and "y" the number of student tickets sold, you have the following system of equations:

[tex]\left \{ {{x+y=1291} \atop {5*x+1*y=3047}} \right.[/tex]

Through the substitution method, you must solve for one of the unknowns in one of the equations and substitute its value in the following one: in this case you solve for the variable y from the first equation:

y=1291 -x

and you replace in the second equation:

5*x + 1291 - x= 3047

Solving, you get:

5*x-x= 3047 - 1291

4*x= 1756

x= 1756÷4

x=439

Replacing this value in the expresion y=1291 -x you get:

y=1291 -439

y= 858

Answer:

x=4

Step-by-step explanation:

48/5x-2 = 40/2x+7

48(2x+7) = 40(5x-2)

96x+336 = 200x-80

-96x           -96x

336 = 104x-80

+80            +80

416/104 = 104x/104

x = 4

The value of x is equal to 4.

we have given that,

If CDG ~ EDF, find the value of x.

2x+7

5x-2

48

40

we have to determine the value of the x.

Two triangles are similar if they have the same ratio of corresponding sides and equal pairs of corresponding angles.

48/5x-2 = 40/2x+7

48(2x+7) = 40(5x-2)

96x+336 = 200x-80

-96x           -96x

336 =  104x-80

+80            +80

416/104 = 104x/104

x = 4

Answer:

9 is divisable by 3.

A number that has 9 as a factor can be divided by 9 so it can also be divided by 3.

If g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2

The given relationship is:

g(1) = 0

g(n) = g(n-1) + n

g(2) = ?

Since g(1) is already known

g(2)  =   g(1)  +  2

Note that g(1) = 0

Substitute g(1) = 0 into g(2)  =   g(1)  +  2

g(2) = 0  +  2

g(2)  =  2

Therefore, if g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2

Answer:

DIMENSIONS:

THE DOUBLE: 42.6 m cubed on both the length, width, and height

THE HALF: 10.6 m cubed on both the length width and height

THE CUBE: 21.3 m cubedon both the lengrh, width, and height

MOST HEIGHT: The Double at 42.6 m cubed

Step-by-step explanation:

We know that we have 64 m cubed. First, we should find out the volume of each cube. 64 times 2 is 128. This means the Double equals 128 in volume and half of 64 is 32. this means the Half is 32 in volume. Since these are all cubes, every side is exactly the same(or else it would be a rectangle) the formula for finding volume is length times width times height, we would divide EACH of the volumes by 3. 128 divided by 3 is 42.6 meaning the doubles dimensions would be 42.6 on each part of the cube (the lenght width and height would all be 42.6) you can check this by multiplying 42.6 by 3 which takes us back to 128. For the cube we would do 64 divided by 3 which is 21.3 pn every side and 32 divided by 3 is 10.6. The one with the most height is the double.

Answer:

X=200

First your going to add all sides together. Once you finish you should get

50+55+90=195

after you got your answer your going to round to the tenths if it's higher than 5 your going to make it 200 but if it's lower than 5 than your going to make it 180.

So in our case because it's 195 we're going to turn it into a 200.

Answer: 13%

Step-by-step explanation:

To find the percent increase, first find the increase in figures:

= 149,160 - 132,000

= 17,160 people

Then find the percent increase in this manner:

= Increase / Previous population * 100%

= 17,160 / 132,000  * 100%

= 13%
