Cross multiply
10 x 9 = 90
3 x k = 3k
make an equality
90 = 3k
divide both sides by 3
90/3 = k
simplify
30 = k
If you would like to solve (2x - 6) * (3x^2 - 3x - 6), you can do this using the following steps:
(2x - 6) * (3x^2 - 3x - 6<span>) = 2x * 3x^2 - 2x * 3x - 2x * 6 - 6 * 3x^2 + 6 * 3x + 6 * 6 = 6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36 = 6x^3 - 24x^2 + 6x + 36
</span>
The correct result would be <span>6x^3 - 24x^2 + 6x + 36.</span>
Hello!
To find how many calories in three cups we can use the proportion below.

To find our answer we can say, "How many times does 3/4 go into 3," and then multiply that number by 90 as shown below.
3÷3/4=4
90(4)=
360Just to verify, we will cross multiply and check our answer
90(3)÷3/4
270÷3/4=360
Therefore, our answer is
D) 360 calories.
I hope this helps!
I would either round it to the 10th or 100th place.
Answer:
1 year=3.2%
2 year=6.4%
3 year=9.6%
Step-by-step explanation:
Since the% increases every year
So for the first year=
3.2% of 1
3.2%×1
3.2%
For second year
3.2% ×2
6.4%
For the third year
3.2% × 3
9.6%
