Answer:
6.
Step-by-step explanation:
Lucy studies one less (-1) than twice the number of hours a week that rose studies (2 * R), lucy studies 11 hours a week. What we do is add 1 hour to lucy's 11, to get 12, then divide by 2 as lucy studies twice the hours. 12 / 2 = 6.
10 y plus 9 y minus 6 y plus 6 y
=> 10y + 9y - 6y + 6y
= 10y + 9y - 0 = 19y
5/100 x 100/1 = ?
10/100 x 20/1= ?
-2. All you’re doing is going from the number you start with and performing the opperations in the order they appear (-4+3-2+6-5=-2)
