Answer:
She will buy at least 10 pounds or more.
Step-by-step explanation:
If each pound costs $4 and she is spending $40 worth, she needs to buy 10 pounds in order to spend the minimum of $40. She can buy more than 10 pounds to keep spending more money. 11, 12, 13, 14, 15, and so forth are all possible numbers in pounds she will buy.

Answer:
she worked 9 hours at sporting goods store and 6 hours on piano lessons.
Step-by-step explanation:
total hours=15
8.47x + 17(15-x) = 178.23
8.47x + 225 - 17x = 178.23
225 - 178.23 = 17x - 8.47x
76.77 = 8.53x
x = 76.77 / 8.53
x = 9
therefore she worked 9 hours at sporting goods centre and the remaining hours (15-9) giving piano lessons.
Answer:
y = - 49
Step-by-step explanation:
Given
7x - 2y = 35 ← substitute x = - 9 into the equation
7(- 9) - 2y = 35, that is
- 63 - 2y = 35 ( add 63 to both sides )
- 2y = 98 ( divide both sides by - 2 )
y = - 49
7-5x-(3+5x)
7-5x-3-5x
4-10x
