Answer:
6 times
Step-by-step explanation:
1. There was no cents left
2. If you roll one and get 50 cents you have to minus it with rolling other number than 'one' 5 times because you'll get 10 minus if you roll another number (50 divided by 10 is 5)
3. If you divid 30 (The rolls) by 5 (amount of roll you have to roll if you get one)
4. It equals 6 and 6 is a even number
5. Sorry this was too confusing
3x^2+ 2x -18x -12
= (3x^2+ 2x) -(18x+ 12)
= x(3x+ 2) -6(3x+ 2)
= (3x+2)(x-6)
Final answer: (3x+2)(x-6)
Answer:
-1
Step-by-step explanation:
the slope of this one is y=x-21
in order for it to be perpendicular the sign changes and the slope flips
but because the slope is 1 you just change the slope to -1
