25. The product of 8 and the difference between a number and 9 is 96. What is the number?
The answer is 13.
So, 8*(x-9)=96
8*12=96
So, what number minus 9=12? 13.
26. When 12 is added to half the sum of a number and 8, the result is 40. What is the number?
The answer is 40.
12+ (x+8)=40
12 +28=40, so what plus 8 =28? 20.
20 times 2 is 40.
27. The difference between a number and 5, when multiplied by 3, is 36. What is the number?
The answer <em />is 17.
(x-5)*3=36
12*3=36, so what minus 5=12? 17.

Step-by-step explanation:
We are told that the veterinarian wants to determine if a supplement with both glucosamine and chondroitin would be more beneficial than glucosamine alone for dogs’ joint health.
In randomized block design, blocking is the arrangement of experimental units in groups known as blocks which are similar to one another.
Looking at the options given, by blocking on size, age or dog breed, the source of variability which led to the inconclusiveness initially would be controlled which then leads to a greater accuracy in result. Since there can be big, medium and small size of dog: there can be older or younger dogs: there can be different type of dog breeds as well. All these can likely affect the results of the experiment.
Whereas, blocking on colour of coat is not an appropriate variable because it has no effect on the experiment.
