Answer:
(1,1) is a solution of the system.
Step-by-step explanation:
Let's solve the system.
y = 2x - 1
5x - 4y = 1
In the first equation, y is already separated as a function of x. So we replace in the second equation;
5x - 4(2x - 1) = 1
5x - 8x + 4 = 1
4 - 1 = 8x - 5x
x = 1
y = 2x - 1 = 2(1) - 1 = 1
(1,1) is a solution of the system.
Answer:
Step-by-step explanation:
Identity used:
Now let us divide the modified expressions:
÷ 
we get:
The answer is C
Explanation: each ride costs $1.25 but they don’t give a number of rides therefore the number of rides is unknown and represents X. 64 was the total value of his money before the rides. With each ride you add -1.25 to 64, which gives diminishing returns for each ride.

15 x 3 = X
45 = X
The number of ways to choose a cone, if order matters, is 45.
Answer:
