Step-by-step explanation:
ok so for number 1 you first have to group the like terms therefore you will now have:
9r-4r+8-6
and now you calculate:
9r-4r=5r
8-6=2
so that means 5r-2 is simplied version for no.1
for number you 2 you first multiply why is inside the brackets by what is in the outside:
2(x+3y)
2x+6y (simplified version)
hope this helps! no problem
Answer:
(a), (d)
Step-by-step explanation:
Use x=2 and evaluate:

Hey there!
"9 pounds more than" means that you'll be adding 9 to the expression.
"half the weight w" means that you'll be calculating half of w each time you solve the equation, or 0.5w.
Your entire expression will be 0.5w + 9.
Hope this helped you out! :-)
