Answer:

c) (-5, -7)

Step-by-step explanation:

In a parallelogram, the midpoints of the diagonals are the same point. This means ...

(R+T)/2 = (S+U)/2

R +T -S = U

(-6 +4 -3, -3 -1 -3) = U = (-5, -7)

Marcia, Jan, and Sydney are sisters Jan is twice as old as Sydney. Marcia is two years older than Jan. Altogether the ages are u

Mrrafil [7]

Answer:

Step-by-step explanation:

m + j + s = 37

j = 2s......s = j/2 or 1/2j

m = j + 2

(j + 2) + j + (1/2j) = 37

2j + 1/2j = 37 - 2

2j + 1/2j = 35....multiply everything by 2 to get rid of the fraction

4j + j = 70

5j = 70

j = 70/5

j = 14 < ==== Jan is 14

m = j + 2

m = 14 + 2

m = 16 <==== marcia is 16

s = 1/2j

s = 1/2(14)

s = 14/2

s = 7 <==== sydney is 7

1/5x + 1/2 = 3 + 1/2x

lawyer [7]

Answer:

X=-25/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1/5x+1/2-1/2x=1/2x+3-1/2x

-3/10x+1/2=3

Step 3: Subtract 1/2 from both sides.

-3/10x+1/2-1/2=3-1/2

-3/10x=5/2

Step 4: Multiply both sides by 10/(-3).

(10/-3)*(-3/10)=(10/-3)*(5/2)

X=-25/3

Hope that helps :D
