Answer:
<em>4x+7y≤250</em>
Step-by-step explanation:
<u>Inequalities</u>
Let's call:
x = number of small rides
y = number of big rides
Since each small ride costs 4 tickets, x rides cost 4x tickets.
Since each big ride costs 7 tickets, y rides cost 7y tickets.
The total number of tickets is the sum of both:
Total tickets = 4x+7y
The friends have 250 tickets, so the total tickets of the rides cannot be greater than the 250 tickets available, thus:
4x+7y≤250
Answer:
y = -3/4x - 3
Step-by-step explanation:
...................
Given that XZ = 8x - 2 and YZ = 2x + 1 and that Y is the midpoint of line XZ.
2YZ = XZ
2(2x + 1) = 8x - 2
4x + 2 = 8x - 2
8x - 4x = 2 + 2
4x = 4
x = 1.
Put 65 over 100 so it's a fraction and simplify from there i think
= 8xy - x -2xy + 3x
= 6xy + 2x ..............combine like terms
answer
3. 6xy + 2x
