Answer:
B and J switch because J is a repeating number and repeating numbers are irrational because they don't have a definte end. Other than that, you are good!
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
Distribute the 2 on the right and the -1 on the left: 13 - 2x - 2 = 2x + 4 + 3x
Combine like terms on each side of the equation: 11 - 2x = 5x + 4
Add 2x to both sides, and subtract 4 from each side: 7 = 7x
Divide both sides by 7: x = 7

a(b+c)=ab+ac
3(x+7)=3x+21
Answer:
x=6
Step-by-step explanation:
Goal: "solve for x" in 3 - 2x = -1.5x.
First: Add 2x to both sides to isolate x:
3 = 0.5x
Next, divide both sides by 0.5, again to isolate x:
3/0.5 = x, or x = 6
