Step-by-step explanation:
To find the answer, we need to calculate the least common multiple of 252,308 and 198
252=
×
×7
308=
×7×11
198=2×
×11
Then <em>least common multiple</em> is
×
×7×11=2772 seconds
2772 = 46×60 + 12
Therefore 2772 secondsis equal to 46 minutes 12 seconds.
Combine like terms to simplify.
3z + 5z = 8z
4 - 9 = -5
8z - 5
Answer: 8z - 5
