Answer:
9 pieces
Step-by-step explanation:
28 inches rope cut into 3-inch pieces
There is no matching answer choice, if given numbers are correct then the answer is 9 full pieces
---------
<u>Note:</u>
- The close answer choice is 8
- 28/8 = 3 1/2 or 3.5
- So if cut into 3.5 inch pieces then it is 8 full pieces
- just in case it was typo 3 instead of 3.5
Answer:
-3x^2+12x
Step-by-step explanation:

Answer:
1) 4
2) 45
3) 104
Step-by-step explanation:
1)
let x be your number.
((6x+8)/4)-5 = 3
add 5
(6x+8)/4=8
multiply by 4 to get rid of the denominator
6x+8=32
subtract 8
6x=24
divide by 6
x=4
2) Same type. (this time I won't explain every step)
let x be your number
((x/9)-8+6)*7 =21
(x/9)-8+6=3
(x/9)-2=3
x/9 = 5
x=45
3) Same type... Again
let x be your number
(((x-4+11)*2)/6)-8 = 29
((x-4+11)*2)/6=37
(x-4+11)*2 = 222
x+7=111
x= 104
