Answer: a=225 adult, s=200 student
Explanation: We need a system of equations to find how many of each ticket Marc sold and we can use 4s+5a=1925 and s+a=425.
If we isolate a, we will have a=425-s
If we plug this into the first equation, we will get 4s+2125-5s=1925
Solving for s gives us s=200.
To find a, we can do 425-200 to find that a=225.
9 inches long
9 divided by 10 is .9
multiply it by 10 (to get the length of the purple ribbon) and the answer is 9
= -15(x - 5)
distribute the -15 over the parentheses:-
= -15x + 75
31.415 to the nearest unit
After the 31, the next digit 4 is not up to 5 so we round down .
31.415 ≈ 31 to the nearest unit.
