8, 2 because A doesn't add anything.
Answer:
1
Step-by-step explanation:
x is 1 and y is 1 and the total is three so 1
Answer:
x + y = 745
23.50x + 58.75y = 29,668.75
Step-by-step explanation:
Since 745 copies were sold and x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold:
x + y = 745
Since the home edition costs $23.50, and the business edition costs $58.75:
The money earned from home edition is = 23.50x
The money earned from business edition is = 58.75y
Since the company earned $29,668.75:
23.50x + 58.75y = 29,668.75
Answer:
kevin is 6 years old
Step-by-step explanation:
Let Kevin's age now be a
Daniel's age now be b
Kevin is 3 years older than Daniel. -> a-3 = b
Two years ago, Kevin was 4 times as old as Daniel -> a-2 = 4(b-2) = 4b -8
-> a-3 -(a-2) = b - (4b-8)
-> - 1 = -3 b +8
-> -9 = -3b
-> b = 3
-> a = 6
