Greater than 3.1×10^-3
3.1×10^-2, 5.8×10^-3
Between 3.1 × 10^-3 and 4.3 × 10^-5
2.1×10 ^-3, 3.5×10^-4, 5.2×10^-4
Less than 4.3 × 10^-5
4.2×10^-6, 3.2×10^-5
Step-by-step explanation
:
Lin's number = l
pazi's number = p
l = p + 7
p = p
p + 7 + p = 49
2p + 7 = 49
2p + 7 (-7) = 49 (-7)
2p = 42
2p/2 = 42/2
p = 21
l = p + 7
l = 21 + 7
l = 28
pazi is 21 years old, Lin is 28 years old
hope this helps
