Answer:
x=-1
Step-by-step explanation:
3x−12=5(x−2)
3x+−12=(5)(x)+(5)(−2)(Distribute)
3x+−12=5x+−10
3x−12=5x−10
Step 2: Subtract 5x from both sides.
3x−12−5x=5x−10−5x
−2x−12=−10
Step 3: Add 12 to both sides.
−2x−12+12=−10+12
−2x=2
Step 4: Divide both sides by -2.

x=-1

Answer:
2.7 L
Step-by-step explanation:
400 mL = .4 L
800 mL = .8 L
1,500 mL = 1.5 L
.4 + .8 + 1.5 = 2.7 L
The third one is the answer
(1,5)

The answer to the question
Answer:
30
So the two sectors add to the full length:
JK + IJ = IK
x+6 + 9 = 2x
Rearrange:
x=15
So the numerical length:
2x
2*15
30
