Okay so the first one is 3 dollars each..because if you subtract 9 from 21 you will be left with 12 dollars so if he spent the money on FOUR tickets it would be 3 because 3 times 4 is 12 :)
The distributive property
First you to eliminate i from denominator.
mult by (7+3i) above and below
=(49+42i-9)/(49-9)
which is (40+42i)/40 which can simplify
<em>n = 4</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>²⁾2n + n/2 = ²⁾10</em>
<em>4n + n = 20</em>
<em>5n = 20</em>
<em>n = 20 : 5</em>
<em>n = 4</em>
<em>Good luck !</em>
1) 129.48 lbs : Multiply 156 by 0.17 to get 26.52, then 156 by 26.52 to get 129.48.
2) 1.96 : take 166.52 and divide that by 85. You will get 1.9590... and a lot of other crazy numbers. Round it to the nearest cent, you get 1.96.
3) 0.93 minutes : the faster time is 9.97 and the slowest is 10.9, subtract that and get 0.93.
4) 20.75 : add the prices up all together and you get 20.75
5) 18.32
6) 16.754
7) 56.44
8) I can't see the sign
9) 161.7
10) 737.49
11) 250
12) 405
