Answer:
Can anyone solve this?
2 answers:
C) The equation can be rewritten as:
6! and 10! in the numerator and denominator cancel out. Leaving you with:
Simplify:
= 100.1
d) (2 + 4)! = 6!
6 * 5 * 4 * 3 * 2 * 1
30 * 12 * 2
360 * 2
720
e) Just like in part c, we can rewrite the numerator:
The 24! in the numerator and denominator cancel out. Leaving you with:
f) Just like part c and e, we can rewrite the denominator:
15! cancels in both top and bottom. Leaving you with:

7. For this one, we need an equation. Lets make x = the price of the computer. Since the price of the printer is 30% the price of the computer, we can make that .3x, because a number multiplied by .3 will give you 30% of your original number. So, our equation will be:
Since x is the cost of the computer, you have your answer right there. The computer costs $2,028.
8. For this one we're going to need a proportion, but first we need to find out how much of the percentage of seeds Cliff planted.
% of seeds planted per person:
Ali - 40
Ben - 45
Cliff - x
All percentages add up to 100, so we'll make an equation to figure this out:
Therefore, Cliff planted 15% of the seeds. Since Cliff planted 15% of the seeds, and he planted 87 total, 15% of our total number of seeds planted is 87. We can now make a proportion to figure out how many seedlings were planted all together.
We can now cross multiply in order to get a solvable equation:
The total number of seedlings planted was 580.
Sorry if this is confusing at all, hope I helped!
