Answer:
4⅝
Step-by-step explanation:
7¾ − 3⅛
Write as improper fractions.
7¾ = (7×4+3)/4 = 31/4
3⅛ = (3×8+1)/8 = 25/8
31/4 − 25/8
Find the common denominator (in this case, 8).
62/8 − 25/8
Subtract:
37/8
Convert to proper fraction. 8 goes into 37 4 times with a remainder of 5.
37/8 = 4⅝
The price of each ticket is $42.50. So if Selene buys x tickets, the cost of x tickets will be 42.50x.
She has to pay $5 handling fee as well for purchasing the tickets online. So her total cost of the tickets will be:
Total Cost = 42.50x + 5
Selene got $250. This means she can spend a maximum of $250 on the tickets. Maximum of $250 means less than or equal to $250.
So, we can write the spending on the tickets in the form of following in equality:
42.50x + 5 ≤ 250
42.50x ≤ 245
x ≤ 5.76
This shows, Selene can buy 5.76 tickets. Since the number of tickets has to be a whole number we look for the nearest possible number. She cannot buy 6 tickets, as the cost will exceed $250. So the maximum tickets she can buy are 5.
Therefore, the correct answer is option A
Multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6
<h3>How to expand quadratic equations?</h3>
We want to expand the quadratic equation given as;
(x + 2)(4x - 3)
Multiplying out gives us;
4x² + 8x - 3x - 6
⇒ 4x² + 5x - 6
Thus, we can conclude that multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6

If you would like to calculate A + B and B - A, you can do this using the following steps:
A = 3 * X - 2
B = - 6 * X - 7
A + B = (3 * X - 2) + (- 6 * X - 7) = - 3 * X - 9
B - A = (- 6 * X - 7) - (3 * X - 2) = - 9 * X - 5
The correct result would be B.
Your wage would be $122.5, (8.75)(14)
