27

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

Michael hits the bulls-eye on a dart board 18 out of 30 tries

The proportion is: 18 hits / 30 times= 18/30

For 45 times:

x hits / 45 times

Where x is the number of hits out of 45 times.

So:

18/30 = x/45

Solving for x:

[18/30] 45 = x

x =27

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
