Mathematics
1 answer:
Elan Coil [88]2 years ago
3 0

Answer:

y=-1/7+48/7

Step-by-step explanation:

You want to isolate the Y so you subtract the x to the other side.

Next you divide both numbers on the right hand side by 7 and that gives you

y=-1/7+48/7

A farmer has 1800 m of fencing. He needs to create
NeTakaya

Answer:

67,500 m²

Step-by-step explanation:

ASSUMING the fields look like this __________________

                                                            |                    |                   |

                                                            |                    |                   | W

                                                            |_________|_________|

                                                                                L                                                            

Let L be the length of the combined field and W be the width

2L + 3W = 1800

2L = 1800 - 3W

L = 900 - 1.5W

A = LW

A = (900 - 1.5W)W

A = 900W - 1.5W²

Area will be maximized when the derivative equals zero.

dA/dW = 900 - 3W

        0 = 900 - 3W

     3W = 900

       W = 300 m

L = 900 - 1.5(300)

L = 450 m

A = LW = 450(300) = 135,000 m²

so each sub field is 135000/2 = 67,500 m²

A brick is 5/7 of a foot tall. If you need to build a brick wall that is 10 feet tall, how many bricks tall will the wall be?
svlad2 [7]

Answer:

7 1/7

Step-by-step explanation:

For the problem:

5 /7 × 10  = ?

Convert any mixed numbers to fractions:

10 = 10

Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:

5 × 10

7 × 1

=  

50 /7

50 ÷ 7 = 7R1, therefore:

50 /7 =  7 1/7

The result is:

5

7

× 10 = 7 1/7
