3. Through January 2014, Beyonce has been nominated for ten more bet awards than Jay-Z. Determine how many nominations, total of 50. will medal

Answer 1

Kenny buys one shirt and two hockey pucks. It totals to be $36. Let's make 's' represent shirts and 'p' represent pucks.
s + 2p = $36

Kyle bought two shirts and three pucks and paid $64
2s + 3p = $64

Let's rewrite the first equation to isolate the variable 's':
s + 2p - 2p = $36 - 2p
s = $36 - 2p

Now we know what 's' is equal to, so we can plug it into the second equation.

Answer 2

@Aveline what about others?

Answer 3

You use the exact same process for the other equations.
For example, on number two, the two equations would be:

5h + f = $4.44 (where h=hamburgers and f=fries)
4h +2f = $5.22

Answer 4

I'm still confused! @Aveline
