Answer:
Let the price of one senior citizen ticket be <em>sc</em> and the price of one student ticket be <em>st</em>.
Let's write equations using the information given and the variables above:
=> 5sc + 15st = $137.50
=> 20sc + 44st = $430
Hmm.. We can multiply 5sc by 4 to get 20sc.
=> 4(5sc) + 4(15st) = 4($137.50)
=> 20sc + 60st = $550
Now we can subtract the second equation from the first to determine the price of a student ticket.
20sc + 60st = $550
- 20sc + 44st = $430
=> 16st = $120
=> st = $7.5
So, the price of a student ticket is $7.5.
Answer:
18 m
Step-by-step explanation:
1cm=2meters
so 9 cmx2=18meters. the corridor will be 18 meters
2*2 is the answer of 2 multiplied by the cube root of 2
(if this helps) commutative
4 1/2 + 2 4/5
4 + 2 = 6
1/2 + 4/5 = 5/10 + 8/10 = 13/10 = 1 3/10
6 + 1 3/10 =
7 3/10 <===
