34 = q + n
6.1 = .25q + .05n
-1.7 = -.05q - .05n
6.1 = .25q + .05n
4.4 = .2q
q = 22
22 of the coins are quarters.
Answer:
the required answer is 64
Step-by-step explanation:
b/4 =16
b = 16 × 4
= 64
Answer:
1/4 of the times
Step-by-step explanation:
because there are 4 sections, that means that there is a 1/4 probability.
Let's call the number you thought of n. Then what the two steps you took can be written as an equation:

Subtract n to get all of your variables to one side:

At this point, I recommend turning your mixed number into an improper fraction. It will make things easier later on:

Now divide both sides by 11 to get the value of n:
200+ 10 + 6= 216
