Answer:
Andrew has 22 puppies, Carla has 7 puppies.
Step-by-step explanation:
Let's set up an equation.
Carla and Andrew have 29 puppies.
C + A = 29
Andrew has 8 more than twice Carla.
A = 2C + 8
Let's use substitution by plugging A into C + A = 29.
A = 2C + 8 & C + A = 29
C + (2C + 8) = 29
Now, let's combine like terms.
3C + 8 = 29
Subtract 8 from both sides.
3C = 21
Divide both sides by 3.
C = 7
Carla has 7 puppies. Plug in this value back into C + A to find how many puppies Andrew has.
C + A = 29
7 + A = 29
A = 22
Andrew has 22 puppies.
Let's check our work. Plug in Andrew and Carla's number of puppies back into our original equations.
C + A = 29
7 + 22 = 29
29 = 29
Correct!
A = 2C + 8
22 = 2(7) + 8
22 = 14 + 8
22 = 22
Your answer is correct!
Hope this helps!
