So prime factorization is as it seems, finding the prime factors for a number. With this number, break it down as such:
<u>Looking at our factors, the prime factorization of 6400 is 
</u>
80% of x = 16
"of" translates to multiplication and 80% becomes 80/100.
80/100 × x = 16
0.8x = 16
0.8x/0.8 = 16/0.8
x = 16/0.8
x = 20
Your final answer is 80% of 20 is 16.
Answer:
y=-5x+2
Step-by-step explanation:
desmos
also -5= the slope and 2 was the y intercept aka B you had all Pieces
Q18)
7/0.75 = 28/3
28/3(45) = 420 -> 420/60 = 7
Therefore the answer is B. 7 minutes.
Q20)
60.90/5 = 12.18
12.18(7) = 85.26
85.26+14.99 = 100.25
Therefore the answer is D. $100.25.
