You just multiply the numerators of the fractions and the denominators of the fractions together, and then reduce the fraction to simplify it from that point on.
Answer:
7680 rabbits
Step-by-step explanation:
Let y represent the number of rabbits after x days and let x represent the number of days. This is an exponential growth equation in the form:

Since there is an initial value of 26 rabbits on the farm and the rabbits double every 30 days, hence the equation becomes:

Diana's age=21 years
Carmen's age=x years
Andrew's age=2x years
21+x+2x=45
21+3x=45
3x=45-21
3x=24
x=24/3
x=8
2x8=16
Carmen is 8 years old and Andrew is 16 years old. Hoped that helps:)
D because a straight line is 180 degrees. Since 2x+15 and 65 add up to a straight line (180 degrees) in the picture, the answer is D.
