Answer: 325
Step-by-step explanation:
Student tickets: x
Adult tickets: x + 71
Total: 579
x + x + 71 = 579
2x + 71 = 579
2x = 579 - 71
2x = 508
x = 508/2
x = 254
Adult tickets = x + 71 = 254 + 71 = 325

Answer:
4
Step-by-step explanation:
You take 3/4 + 3/4 and add it. That equals 1.5, so you take 3/4+ 3/4 again and you get 1.5 . So, 1.5+1.5 is 3. So that's how you get your total of 4 boxes.
Answer:
Joy definitely does have enough soup for 22 people.
Step-by-step explanation:
Upper Bound: 285ml turn it to 0.285 L 10÷2=5
280ml :
Lower Bound: 275ml turn it to 0.275 L
Upper Bound: 6.75 L 0.5÷2=0.25
6.5 Litters :
Lower Bound:6.25 L
6.75÷0.275=24.54 or 25
6.25÷0.285=21.92 or 22
Answer:
x = -2
Step-by-step explanation:
7x -6y = -20
y=1
7x - 6 = -20
7x = -14
x = -2
Answer:
a. y = x + 3
Step-by-step explanation:
All three ordered pairs satisfy the first equation.
___
If you want to look into it a little further, you can notice that if you sort the ordered pairs by their x-values, you get ...
(-1, 2), (0, 3), (1, 4)
That is, the y-values increase (by 1) as the x-values increase (by 1).
All of the other answer choices have -1 as the coefficient for x, which means the y-values will decrease as x increases. None of these choices (b–d) is viable.
