Answer:

4t + 15j > 800

Please read explanation below as well.

Step-by-step explanation:

We know the following information:

- The number of T-shirts is represented by the variable t. Each T-shirt costs $4. The total cost depending on the number of T-shirts can be represented by 4t.

- The number of jeans is represented by the variable j. Each pair of jeans costs $15. The total cost depending on the number of jeans can be represented by 15j.

- The stores want to sell more than $800. This idea is represented mathematically by writing >800.

The total cost of jeans and T-shirts depending on the quantities of each of them is represented as a sum: 4t + 15j. This total cost has to be more than $800: 4t + 15j > 800.

Natalija [7]
If you would like to know how many minutes will it take you to mow a lawn that measures 6000 square feet, you can calculate this using the following steps:

800 square feet ... 15 minutes
6000 square feet ... M minutes = ? 

800 * M = 15 * 6000
M = 15 * 6000 / 800
M = 112.5 minutes

This will take 112.5 minutes.

Diego is thinking of two positive numbers. He says, 'If we triple the first number and double the second number, the sum is 34.'
UNO [17]

1st number: 0

2nd number: 17

Answer

Step-by-step explanation:

3x+2y=34 x is the first number, y is the second.

1/2x+2y=34 multiply each number by two to get rid of the integer by the variable x.

x+4y=68 solve for x.

x=68-4y add this into the first equation to solve for variable y.

3(68-4y)+2y=34 solve for y.

204-10y=34

-10y= -170

y=17

now to solve for x

x= 68-4(17)

x= 0

What’s the answer to this question? I’m confused as to how to do this.
choli [55]

Answer:

x = 20

Step-by-step explanation:

(3x + 50) = (6x - 10)

Subtract 6x on each side

3x + 50 - 6x = -10

Combine the x values together

-3x + 50 = -10

Subtract 50 on each side

-3x = -60

Divide each side by -3

x = 20
