Answer:
C, as q = 62.
Step-by-step explanation:
When you have an equation, your goal is to get the letter you are solving for alone. To do this, you employ a simple rule: what you do to one side of the equals sign, you must do the other.
To isolate q in -55 + q = 7, you must add 55 to the left side. q is now alone. However, because we added 55 to the left side, we must also do it to the right! 7 + 55 = 62, so the new right side is 62. Hence, we get to this:
q = 62
The answer is now in plain sight!

Answer:
(c) y=-1/2x+12
Step-by-step explanation:
The units of the problem need to be consistent. Here, it is convenient to use feet. 6 inches is 1/2 foot, so the level will decrease 1/2 ft for each hour. It starts at +12 ft, and goes down from there:
y = -1/2x +12
To have the outcome of 2 or more, we can roll out a 2,3,4,5 or 6.
So, the chance of getting the outcome is 2 or more is 5/6
And, 5/6 is pretty much likely to happen. (around 80% or so)
