Serena has 6 photo albums with 15 photos in each
so serena has (6 * 15) = 90 photos.
maya has 8 albums with 13 photos in each.
so maya has (8 * 13) = 104 photos
if serena add another 12 photos to her album....(90 + 12) = 102 photos
so in total, serena and maya have 102 + 104 = 206 photos <=
Since log(ab) = log(a) + log(b) and log(a/b) = log(a) - log(b) for any logarithm base, we have

Then using the change-of-base identity, we have

But we also know that 2¹⁰ = 1024 and 2⁵ = 32, so we can back up slightly and instead write

Then the logarithms cancel and you're left with 5/10 = 1/2.
Christy's average mph is 48 because 132 divided by 2.75 = 48

Answer:
19/24
Step-by-step explanation:
3/8=36/96
5/12=40/96
