Answer: 12/18
Step-by-step explanation:
For a quick explanation, all you need to do is multiply 1/6 by 6 to get 1 whole and do the same to 2/3 so it’s proportional again.
Answer:
110d + 80 > 1620
d > 14
Step-by-step explanation:
The amount of points from collecting diamonds can be represented by 110d, since you get 110 points for each diamond, d
Add 80 to this to represent the bonus points.
Use a greater than inequality, because you have to get more than 1620 points.
Put this all together:
110d + 80 > 1620
Then, solve for d:
110d + 80 > 1620
110d > 1540
d > 14
So, you have to collect more than 14 diamonds in less than 2 minutes in order to advance to the next level.

Answer:
- 4x³ - 33x² + 31x - 3
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
x²(- 4x + 3) + 9x(- 4x + 3) - 1 (- 4x + 3) ← distribute all 3 parenthesis
= - 4x³ + 3x² - 36x² + 27x + 4x - 3 ← collect like terms
= - 4x³ - 33x² + 31x - 3
