Answer:
19 days
Step-by-step explanation:
The first day he saves 2.25.
The second day he has saved 2.25 + 2.25 or 2.25(2).
The third day he has saved 2.25 + 2.25 + 2.25 or 2.25(3)
This continues for x number of days so 2.25x.
If the video game costs 41.95 then set equal to 2.25x and solve.
2.25x = 41.95
x = 18.64
This rounds to 19.
Solving the system of equations, it is found that x = 3, that is, there are 3 128 MB memory sticks.
--------------------
We want to solve for x, thus, in the first equation, we write y as a function of x, that is:
Replacing in the second equation:
x = 3, that is, there are 3 128 MB memory sticks.

HOPE THIS HELPED YA
Volume of the candle:
V = B * h ( where B is the base area and h is the height )
270 = B * 18
B = 270 : 18
B = 15 cm²
B = a * b / 2
B = 5 * b / 2
15 = 2.5 b
b = 15 : 2.5
b = 6 cm
Therefore dimensions of the box are: a = 7cm, b = 6 cm, c = 18 cm.
Answer: B ) 7 by 6 by 18 cm.
