I’ll answer the first question, what’s 3 plus 13? 16 that’s your answer
26.4 minutes. (Just add each of the numbers to get the total, if that helps.)
D)300% because it is an increase so you'd do 240/80=3•100=300
2.5 + 4.25x
2.5 + 4.25(5) = 2.5 + 21.25
= 23.75
Hope this help
Alright. First you would want to find the common denominator of 9 and 5. This is basically a common multiple of both of these numbers. In order to do this, you multiple 7/9 by 5/5 and 4/5 by 9/9. Remember, what you do to the denominator, you also need to do to the numerator. So you get 35/45 and 36/45. Now, just compare the numerators. 36 is obviously greater than 35, so 36/45 is greater which is also 4/5. This makes your answer 7/9 < 4/5
