The answer is 29 flies.
x is the number of weeks. We have 2 weeks, so x = 3
1. Calculate the population of flies after 3 weeks: p(3) = ?
2. Calculate how much flies are eaten by the spider after 3 weeks: s(3) = ?
3. Subtract the number of flies after 3 weeks and eaten flies after three weeks: p(3) - s(3) = ?
1. p(x) = 5 · 2ˣ
p(3) = 5 · 2³ = 5 · 8 = 40
2. s(x) = 3x + 2
s(3) = 3 · 3 + 2 = 9 + 2 = 11
3. p(3) - s(3) = 40 - 11 = 29
Answer:
112 candles
Step-by-step explanation:
We can simply add up the 5 numbers of candles, or we can take advantage of the invention of multiplication to replace repeated addition. The number of candles altogether is the sum of the numbers of candles in each of the 5 boxes.
16 + 4×24 = 16 +96 = 112
The total number of candles is 112.
Since the x values cancel out and we are left with 6=6, all x values will work for x because it will dissapear anyway
with some modification, we can get x=x, so therefor that is true and all values work
C is answer
