<em>( 5 - 2i ) ( 4 - i ) </em><em>18 - 13i</em>
<em>( 2 - 5i ) ( 1 - 4i ) </em><em>-18 - 13i</em>
<em>( 1 - 4i ) ( 5 - 2i ) </em><em>-3 - 22i</em>
<em>( 4 + i ) ( 2 - 5i ) </em><em> 13 - 18i</em>
Just subtract 7 from 25. it is 18
2c+5t=43
c=(43-5t)/2
8c+3t=36 and using c found above in this equation gives you:
4(43-5t)+3t=36
172-20t+3t=36
-17t=-136
t=8, and since c=(43-5t)/2
c=1.5
So a table costs $8.00 to rent and a chair costs $1.50
I think addition property of equality
The answer is a. here’s a picture that hopefully helps explain the reasoning/work
