3x-5=2x-6
Move 2x to the same side as 3x.
3x-2x = x
X-5=-6
add 5 to the -6.
X = 5-6
X=-1

Y=3x-5
y=2x-6

Move the X's to the other side on both equations to make equations easier to solve.

-3x+y=-5
-2x+y=-6

Subtract equations.

-x=1
x=-1

y=3x-5

y=3(-1) -5

y=-3-5
y=-8

~Hope I helped!~

Answer:

  (c)  162 cm

Step-by-step explanation:

The centroid divides a median into parts with the ratio 1:2, so RL:LD = 1:2. Then RL:RD = 1:(1+2), and RD = 3RL.

  RD = 3·54 cm

  RD = 162 cm

HELP MEEEEEEEEEEEEEEEEEEEEEE!

Answer:

first is 1/8, second is 1/10, third is 1/15, and fourth is 1/16

Step-by-step explanation:

1/2 divided by 4 = .5/4

.5/4 = 0.125

.125 = 1/8

1. 1/8

1/5 = .2

.2/2 = .1

.1 = 1/10

2. 1/10

since 1/3 would be a repeating term, you can change 5 to 5/1

3/1 = 3

1/5 = .2

.2/3 = 1/15

3. 1/15

1/4 divided by four = 1/4 divided by 1/4

1 x 1 = 1

4 x 4 = 16

4. 1/16

X = 1
y = -4
xy = (1)(-4) = -4

answer
C) -4


double check:
y - 4  = 4x + 3y = -(9-x)
-4 - 4 = 4(1) + 3(-4) = -(9 - 1)
    - 8 =   -8              = -8
