Answer:
r = (-1)
Step-by-step explanation:
Firstly simplify the brackets,
; -3(1 + 6r) = -3 - 18r
then substitute on the bracket with the simplified form,
; -3 - 18r = 14 - r
then move the values with (r) to one side and the other ones without (r) to the other side
; -3 - 14 = 18r - r
; -17 = 17r
then divide both sides by 17,
; -1 = r
Hence...r = -1
1. 0.23 x 1.2 = 0.276
2. 0.3 x -0.12 x 2.4 = -0.0864
3. (-5/6 x -9/10)/ 17/20
= (-0.83... x -0.9)/ 0.05
= 15
4. (17/18 x -10/21)/ 11/9
= (0.94... x 0.476)/ 1.2...
= 0.37
5. 24.3/3 = 8.1
6. 10.5/1.375 = 7.63
...and so on — sorry I don’t have enough time to finish
Well the expression describes +7. hope that helped
Total Volume is given as 1080 cubic feet.
Height is given as 9 feet.
Length is 2 feet longer than the width, so Length = x+2
If the stall is 10 feet wide, then the length would be 10 +2 = 12 feet.
The volume for that would be 10 x 12 x 9 = 1080 cubic feet.
Yes it is possible for the width to be 10 feet.
Simpliflyed answer would be 3a -21
