Answer:
x=1/2 or 0.5
B. 0.5
Step-by-step explanation:
Step one: Add x to both sides
you then get the equation 7=4x+5
Step two: subtract 5 from both sides
you then get the equation 2=4x
Divide both sides by 4 to undo the multiplication.
2/4=4x/4x
you get x=2/4 which simplifies to 1/2.

Answer:
Step-by-step explanation:
−6x+6−7=2x+8
-1-8=2x+6x
8x=-9
x= -
Step-by-step explanation:
1. x = acceptable weight of candy bar
2. |x - 12| ≤ 0.45
3. x - 12 ≤ 0.45, x - 12 ≥ -0.45
x ≤ 12.45, x ≥ 11.55
4. The acceptable weight range for each candy bar is between 11.55 grams and 12.45 grams.
