Answer:D
Step-by-step explanation:
Your welcome
X = ones, y = fives
x + y = 19....x = 19 - y
x + 5y = 59
19 - y + 5y = 59
19 + 4y = 59
4y = 59 - 19
4y = 40
y = 40/4
y = 10 <=== there are 10 five dollar bills
x + y = 19
x + 10 = 19
x = 19 - 10
x = 9 <=== there are 9 one dollar bills
Answer:
470<x<530
Step-by-step explanation:
Let x be number of acceptable words
|x-500|<300
we write absolute value inequality representing the acceptable number of words, given the fact that absolute deviation is at most 30 words
-30<x-500<30
500-30<x-500+500<30+500
470<x<530.
