When you add any fractions, you need to find a common denominator. In this case they have no common factors so you just multiply them together. First multiply the first fraction by
which gets you
. Then multiply the second fraction by
to get
. Now you can add them together to get
.
(b)
now you can pull out root 2 and get

Answer:
The cost at both Laser Flash and Laser storm would be the same after 4 games
Step-by-step explanation:
Let the number of games be represented as x
Laser flash charges an initial fee of $16 for gear and $4 per game
For Laser flash , the Equation is:
$16 + $4 × x
y= 16 + 4x
Laser storm charges an initial fee of $20 for gear and $3 per game
$20 + $3 × x
y = 20 + 3x
Hence: Equating both costs to each other
Laser flash = Laser Storm
16 + 4x = 20 + 3x
Collect like terms
4x - 3x = 20 - 16
x = 4 games
The cost at both Laser Flash and Laser storm would be the same after 4 games
