Step-by-step explanation:
520 calories
15 mins = 120 calories
65 mins = 65/15 × 120
= 520 calories
So you times 1.35 by 60 and It gives you 81 so its 60 times 34 = 2040
0.0006 in the same way you put it 3/1000/5
First, 126/32 so divide top and bottom by 2
126 / 2 = 63
32/2 = 16
answer
a = 16
and
b = 2
