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
500 x .15 = 75
100/15 = 6.666667
75 x 6.666667 = 500
Answer:
b = 0
Step-by-step explanation:
-10b + 5 = 7b + 5
-10b + 5(-5) = 7b + 5 (-5)
-10b = 7b Because 5 - 5 = 0
-10b - 7b = -17b/0 = 0
Answer:
180, 185, 190
Step-by-step explanation:
5x + (5x + 5) + (5x + 10) = 555
15x + 15 = 555
15x = 540
x = 36
3 number: 36x5 = 180, 185, 190
check: 180 + 185 + 190 = 555
Answer:
d) 12(100) + 12(80) + 12(5)
Step-by-step explanation:
According to the distributive property, if a,b, c, and d are real numbers, then
a(b+c+d)=ab+ac+ad
We want to find the product 12(185).
We can expand 185 as 100+80+5
Our product then becomes;

We expand using the distributive property to get;

The correct choice is D
