Answer:
Price of senior citizen ticket = $7
Price of student ticket = $5
Step-by-step explanation:
<u>Let</u>:
- senior citizen ticket price = a
- student ticket price = b
<u>Equations formed</u> :
- 9a + 10b = 113
- 2a + 10b = 64
<u>Subtract</u> : Equation 1 - Equation 2
- 9a + 10b - 2a - 10b = 113 - 64
- 7a = 49
- a = 7
<u>Finding b</u>
- 2(7) + 10b = 64
- 10b = 50
- b = 5
<u>Solution</u>
- Price of senior citizen ticket = $7
- Price of student ticket = $5
Answer:
Step-by-step explanation:
A is correct.
2/3 > 4/8
5/9 > 7/12 This one is close. They are both nearly 1/2, but 9<12 and when you divide something by 9 the remainder is going to be larger than if you divide by 12.
The second one is incorrect.
3/4 > 5/9 5/9 is close to 1/2. Three quarters is much greater than 1/2
3/10 is much smaller than 5/9
The third one is correct. 1/10 and 5/6 are much larger than the two fractions on the right. The right side = 56/60 which is very nearly one. The left side is nowhere near that large. (I did estimate the right side).
The fourth one is correct. 9/10 is much larger than 2/3 and 5/9 is larger than 5/12. 5/9 is over 1/2 and 5/12 is under one half. So the arrow in the fourth one is going the right way.
