Answer with explanation:

Perimeter of watermelon field =71\frac{1}{3} yard

1 yard =3 feet

So, perimeter

  =71 \frac{1}{3}*3=\frac{214}{3}*3=214feet

Width of Watermelon field = 44 feet

Kaisa , plants watermelon in the field in rows which are  =2\frac{2}{3}=\frac{8}{3} feet apart.

Number of watermelon planted in a single row =x

Let , Length of Watermelon field

         =\frac{8(x-1){\text{feet}}}{3}

Perimeter of field = 2 *[Length +Breadth]

214=2*[44+\frac{8(x-1)}{3}]\\\\\frac{214}{2}=44+\frac{8(x-1)}{3}\\\\107-44=\frac{8(x-1)}{3}\\\\63=\frac{8(x-1)}{3}\\\\x-1=\frac{3*63}{8}\\\\x=\frac{189}{8}+1\\\\x=\frac{197}{8}\\\\x=24\frac{5}{8}

Number of watermelon in a row =24(approx)

Length of watermelon field

 =\frac{8}{3}*\frac{197}{8}=65\frac{2}{3} feet

Let number of rows of watermelon  = y

\frac{197y}{8}=44\\\\ y=\frac{352}{197}=1.7860

 = 2 Rows(approximately)

3.) x-y=1 --> y= x- 1

4.) x-3y=-15 --> y=1/3x + 5

5.) 8x-10y=20 --> y=4/5x - 2

6.) 14x+6y=36 --> y=-7/3x+6

Answer:

D.648 inches​

Step-by-step explanation:

A yard is a unit that mostly used in America and Canadia to measure the length of something field-size, so it's used a lot in sport. One yard equal to three feet, while one foot equals to 12 inches. There is a higher unit than yard called miles which equals to 1760 yards or 1.60934 kilometers.

Since the measurement is 18 yards, the length in feet will be: 18 yards * 3 feet/yard= 54 feet.

The measurement in inch will be: 54 feet * 12 inches/feet = 648 inches.

What is the solution of the equation 70 = 1.4y ?
sdas [7]
So you basically have to divide 1.4 on both sides so you can get y by its self. Once you divide 60 by 1.4 you’ll get 50.

y=50
