I assume you're looking for the value of x?
Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180
Add 5 to both sides: 15x=185
Divide both sides by 15: x=12 1/3
So x is 12 1/3 or 37/3
Hope this helped!
The translation was up 5 and to the left 8
(1 - 0.42)*150 = 63
0.58*150 = 87
87 packages were not priority mail.
You have to double 1 and 50 to get 2 and 100
1:50 = 2:100
1x2=2
50x2=100
So the statement, <em>if she studied for 2 hours, she would have gotten 100%</em>, makes sense
Hope this helps!
