Combine like terms to simplify an expression. For example, all terms with the variable x can be combined into one term. All constants can also be combined.
1) -4x - 10x = -14x
2) -r - 10r = -11r
3) -2x + 11 +6x = 4x + 11
4) 11r - 12r = -r
5) -v + 12v = 11v
6) -8x - 11x = -19x
7) 4p + 2p = 6p
8) 5n + 11n = 16n
9) n + 4 - 9 - 5n = -4n - 5
10) 12r + 5 + 3r - 5 = 15r (the 5 and -5 cancel each other out)
11) -5 + 9n + 6 = 9n + 1
205.50-26= 179.5
179.5/2= 89.75 $ for each dress
You would use the Volume equation L*W*H=V
2 1/2* 3 1/2* 4 1/2= 39 3/8
Answer:
Step-by-step explanation:
Rate per sec = 100 ÷ 9 = 11.111
1 min and 2 sec = 3600 + 2sec = 3602 sec
Metre = 324.21 metre
