<span>B = A + 150
A/B = 3/5
solve the system of equations:
A/(A + 150) = 3/5
5A = 3(A + 150)
5A = 3A + 450
2A = 450
A = $225
B = 225 + 150 = $375
Total = 225 + 375 = $600

So Tom can run in 384seconds and bill can run can run in 83% of Tom’s time so Bill can run his time in 5 minutes and 19 seconds
Answer:
(8a + 3)(a + b + c)
Step-by-step explanation:
8a^2 + 8ab + 8ac + 3a + 3b + 3c =
= 8a(a + b + c) + 3(a + b + c)
= (8a + 3)(a + b + c)
10,000 * 0.01 = 100
The weight of 10,000 samples is 100
HCF of 12 and 15 by Prime Factorization
1. As visible, 12 and 15 have only one common prime factor i.e. 3. Hence, the HCF of 12 and 15 is 3.
2. To find the HCF of 20 and 25, we will find the prime factorization of the given numbers, i.e. 20 = 2 × 2 × 5; 25 = 5 × 5. ⇒ Since 5 is the only common prime factor of 20 and 25. Hence, HCF (20, 25) = 5.
