Answer:
Step-by-step explanation:
The equation of the straight line passing through the points (0,-7) and (3,-5) will be
⇒
⇒ ......... (1).
Now, the inequality shades the upper portion of the straight line.
Therefore, the y value for the inequality will be more than y value for the equation corresponding to a fixed value of x.
Hence, the inequality equation will be . (Answer)
Answer:
31
Step-by-step explanation:
Let number of ten dollar bills be x .
So, number of five dollar bills = 2 x
Total amount of money in the cash register = 620 dollars
Amount of money in total cash as a result of five dollar bills = 2 x × 5 = 10 x dollars
Amount of money in total cash as a result of ten dollar bills = x × 10 = 10 x dollars
According to question ,
Total amount of money in the cash register = Amount of money in total cash as a result of five dollar bills + Amount of money in total cash as a result of ten dollar bills
⇒ 620 = 10 x + 10 x
⇒ 620 = 20 x
⇒ x = = 31
So, number of ten dollar bills = 31
