so hmm notice, we use the decimal format for the percent, namely 15% is just 15/100 and 5% is just 5/100 and so on
whatever the amounts of "x" and "y" are, they must add up to 100 grams
thus x + y = 100
and whatever the concentrated amounts are, they'll add up to (100)(0.15)
thus
solve for "x", to see how much 5% alloy will be needed
what about "y"? well y = 100 -x

Answer:
26.3
Step-by-step explanation:
33+27.2–(6.8+24)–3.1
Add 33 and 27.2 to get 60.2.
60.2−(6.8+24)−3.1
Add 6.8 and 24 to get 30.8.
60.2−30.8−3.1
Subtract 30.8 from 60.2 to get 29.4.
29.4−3.1
Subtract 3.1 from 29.4 to get 26.3.
26.3
I hope it helps.
Answer:
Simplified version: 10x^5 - 1x^4 + 2x^3 - 6
Step-by-step explanation:
Since your birthday is 10/1/2006 we can use 1012006 as our digits.
We can make a random polynomial: 10x^5 - 1x^4 + 2x^3 + 0 x^2 + 0x - 6
(since 0 are meaningless we can simply this further into the below equation)
10x^5 - 1x^4 + 2x^3 - 6
