There are 6,840 different combinations of people for president, secretary, and treasurer, assuming that each person may have a single job at a time.
Start with 20 candidates for president.
That leaves 19 people for secretary.
And there are 18 people remaining for treasurer.
20 • 19 • 18 = 6,840
Answer:
300 cupcakes
Step-by-step explanation:
Okay, the first step is finding 25% of 240, we do this by multiplying .25 by 240. This gets us 60. Then, to get 125% of 240 (since sales dropped 25%), we add 240 and 60, this gets us 300. 300 cupcakes were sold. Another way to do this is 1.25x240. I wanted to explain it more thoroughly, though.
Answer: x = -3, y = 2
<u>Step-by-step explanation:</u>
3x + 2y = -5 → 3(3x + 2y = -5) → 9x + 6y = -15
4x - 3y = -18 → 2(4x - 3y = -18) → <u> 8x - 6y </u>= <u>-36 </u>
17x = -51
<u> ÷17 </u> <u>÷17 </u>
x = -3
3x + 2y = -5
3(-3) + 2y = -5
-9 + 2y = -5
<u> +9 </u> <u> +9 </u>
2y = 4
<u> ÷2 </u> <u>÷2 </u>
y = 2
