Answer:
Step-by-step explanation:
We have the equation 19 - s = 13, and are asked to determine whether s = -6 fits in.
To solve, we need to isolate "s", do as followed and subtract 19 from both sides :
s = -6
Since this is equal to what the question is asking, yes s = -6 is correct.
For the second one 1 mph equals 1.6 km so i’m pretty sure it would be all of them
Answer:

Step-by-step explanation:
A fraction can be found be taking the current amount over the total amount:

Since Darlene has only typed 23 pages out of 59, her fraction is 23 over 59. Fractions must always be in simplest form, which means that both the numerator and denominator can no longer be divided by the same factor. Since the numbers 23 and 59 are both prime and have no other factors other than 1 and themselves, the fraction 23/59 is in simplest form.
5.95 + 2.95 = 8.9
8.9 + 29.95 = 38.85
62.35 - 38.85 = 23.5
So Daniel spent $23.50 on long distance calling
