6 0

so what you want to do is

5-2=3x =3                             7+(-4)=3

3/3=0

so the length of AC would be zero

The area of a rectangle is 53.3 in2. If the width is 6.5 in, what is the perimeter of the rectangle?
Nuetrik [128]
You can find the length from
  A = LW
  53.3 in² = L×(6.5 in)
  (53.3 in²)/(6.5 in) = L = 8.2 in

The perimeter is twice the sum of length and width.
  P = 2(L +W)
  P = 2(8.2 in +6.5 in) = 29.4 in

The perimeter of the rectangle is 29.4 inches.

Answer:

1. b.(03)

2. A.(6,12)

3. C.(10,-1)

4. (-9,2)

Please mark me BrainIIest

Step-by-step explanation:

1.I will solve your system by substitution.

−x+2y=6;6y=x+18

Step: Solve−x+2y=6for x:

−x+2y+−2y=6+−2y(Add -2y to both sides)

−x=−2y+6

\frac{-x}{-1} =\frac{-2y}{-1} Divide by -1

x=2y−6\

Well I did this problem differently I substitute

Step: Substitute2y−6for x in6y=x+18:

6y=x+18

6y=2y−6+18

6y=2y+12

6y+−2y=2y+12+−2y

4y=12

\frac{4y}{4} =\frac{12}{4}

y=3

Step: Substitute3 for y in x=2y−6:

x=2y−6

x=(2)(3)−6

x=0

Your final answer will be x=0 and y=3
