System of linear equations
a: adult ticket price and c: child ticket price
Step-by-step explanation:
This system of equations can be used to find the price of the adult and child tickets.
We have two equations (one for each day) and two unknowns (adult ticket price and child ticket price).
Let a: adult ticket price and c: child ticket price,
we have for the first day that 3 adult tickets and 1 child ticket adds $38:
and for the second day we have that 2 adult tickets and 2 child tickets adds $52:
If we write this as a system of equations, we have:
The value of the expression is 19
Step-by-step explanation:
- Step 1: Find the value of 9(n + 2) - 5n when n = 1/4
⇒ 9(n + 2) - 5n = 9(1/4 + 2) - 5 × 1/4
= 9(9/4) - 5/4
= 81/4 - 5/4 = 76/4 = 19
