45 or below?? is there suppose to be a speed that she is driving
Answer:
u = 15
Step-by-step explanation:
I must assume you meant u - 16 = -1, as +-16 is in improper format.
Solve u - 16 = -1 for u by adding 16 to both sides:
u = 15
If there are x $13 each books and y $17 each books, then we can build the following equations:
x + y = 8 (or y = 8 - x)
13x + 17y = 128 (or y = 128/17 - 13x/17)
