<span>2 significant digits.
Let's see what the range of possible values you can have for 1.3540980 if your uncertainty is +/- 2%
2% of 1.3540980 = 0.02 * 1.3540980 = 0.027082
So the lowest possible value for your result is
1.3540980 - 0.027082 = 1.327016
The largest possible result is
1.3540980 + 0.027082 = 1.38117996
Notice that only the 1st 2 digits of the result match which is reasonable since a 2% error means that your result is only accurate to within 1 part in 50.</span>
P + 10 = 20 Subtract 10 from both sides
P = 10
Substitute P = 10 into P + Q = 16
P + Q = 16 Plug in 10 for P
10 + Q = 16 Subtract 10 from both sides
Q = 6

Answer:
q=5c
Step-by-step explanation:
q is the total number of questions, so the other numbers/variables must be multiplied together to equal q.
c is the number of chapters read, so that must be multiplied by 5 (questions per chapter) in order to equal q.
