A field has an area of 9/20 square mile. Determine the width of the field if the length is 9/10 mile long.

Answers

so a mile is 5280 ft, and if the are is 9/20 of a miles than find the miles area which is: 27878400 ft squared. then multiply the number by 9/20. and you get 12545280 ft squared.
Now that we have the Area: 12545280
Length is 9/10 of a mile. so 9/10x5280= 4752
L x W= A
4752W=12545280
Divide so you get W= 12545280/4752.
which is equal to 2640ft= W

X-12y=-210 and x-6=90

Answers

Answer:

x = -30

y = -20

Step-by-step explanation:

x - 12y = 210..... (I)

x - 6y = 90..... (II)

Subtract equation (II) from (I)

- 12y - (-6y) = 210 - 90

-12y + 6y = 120

-6y = 120

Divide through by -6y

Therefore, y = -20

Substitute y = -20 in equation (II)

x -6 (-20) = 90

x + 120 = 90

x = 90 - 120

x = -30
