This is actually a very simple problem when you understand how to do it.
First, I would add the 12 to both sides.
Equation would now look like this x/6=24
Then I would do the inverse (opposite) of division which is multiplication.
So multiply 6 to both sides so we can get the x alone. 6*12=144
Now x is alone, and X = 144.

Answer:
Step-by-step explanation:
<span>y − 1 = 4(x + 3)
y - 1 = 4x + 12
y = 4x + 13, slope = 4
parallel lines, slope is the same so slope = 4
</span><span>passes through the point (4, 32)
</span>y = mx+b
b = y - mx
b = 32 - 4(4)
b = 32 - 16
b = 16
equation
y = 4x + 16
Answer:
C). 0.39 grams
Step-by-step explanation:
First find how many half-lifes are in 3 hours:
3 hours ÷ 20 minutes = 9 half-lifes
Find the total left:
0.5^9*200 ≈ 0.39
