Answer:
Well, for (D), the answer would be 32.
Step-by-step explanation:
Because, 20 +12 =32. And 32 - 12 = 20. With the other ones that add, its the same way. You can just for example, if its -5 + b = -40, you can just go 5 - 40= which equals 35. Which should give you 40 if you add 35 and 5 together.
L think. the answer is 26
Answer:
36 pi or 113.04 cm squared
Step-by-step explanation:
You would multiply 2/5 by 2/2 to get 4/10, your common denominator ends up being ten so you have 3/10 and 4/10.
So, the puppy gains 1.375 ounces per week.
That’s 7.875 ounces per month and 94.5 ounces per year.
Since there are 16 ounces in 1 pound, divide 94.5 ounces by 16.
That gives you 5.91 pounds per year.
Now, multiply that by 3 years.
The puppy will weigh 17.72 pounds at three years old.
