Examine the system of equations.
MakcuM [25]

Answer:

\boxed{\boxed{\sf x=-3}}

Step-by-step explanation:

\sf y = -3x - 2

\sf y=7

We'll substitute y into the equation:

\sf 7 = -3x - 2

Switch sides:

\sf -3x-2=7

Add 2 to both sides

\sf -3x-2+2=7+2

\sf -3x=9

Divide both sides by -3:

\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}

\sf x=-3

Therefore, the value of x/solution is -3

CAN SOMEBODY PLEASE HELP ME!!!!!!!!!!
lana66690 [7]

The answers to the blanks are

1. 600,

2. 120,

3. 120,

4. 180.

Explanation:

  • The fence means perimeter around the court. So a tennis court's perimeter is 600 feet fence. The perimeter of a rectangle is 2 times the sum of the rectangle's length and the rectangle's width.
  • It is given that length equals 60 more than width i.e. l = w + 60, where l is the length of the court and w is the width of the court.
  • The perimeter of a court = 600 = 2 (l + w) = 2l + 2w = 2 (w +60) + 2w,                                                                                                     this becomes, 2w + 120 + 2w = 600; 4w = 480, w = 120.
  • Since l = w + 60, l = 120 + 60 = 180. So length of a court is 180 feet and the width of a court is 120 feet.
