8p + 3q - 18 when p = 1/2 and q = 7

You are given that p is equal to 1/2 and q is equal to 7, so plug these values into p and q in the expression to find your answer.

Rewrite your expression to include the values of p and q plugged in. Your expression should look like:

8(1/2) + 3(7) - 18

According to PEMDAS, multiplication should be solved first before doing subtraction, so multiply 8 by 1/2 and 3 by 7. Rewrite your expression; your expression should look like this:

4 + 21 - 18

According to PEMDAS, addition and subtraction should be solved from left to right; they are not prioritized. So solve the expression from left to right and then you will have your answer.

4 + 21 = 25

25 - 18 = 7

Your answer is 7.

Answer:

Step-by-step explanation:

(a is in the file)

B. An add 3 inches to height would affect the surface area more than 3 inches to weight because if the same number was multiplied to 0.13 and 0.08… 0.13 would have the greater outcome.

c. a number more than 10 but less than 11 is 10.5

The height is 50 so plug those two numbers into the equation

10.5=0.08W+(0.13)50-1.03

10.5=0.08W+ 6.5-1.03

10.5=0.08W+5.47

Subtract 5.47 from both sides

5.3=0.08

Divide by 0.08 on both sides

= 62.87lbs in one possibility for the value of W

D. a number between 12 and 13 is 12.5

12.5= 0.08w+ 0.13H-1.03

Subtract 1.03 on both sides

11.47= 0.08w+ 0.13H

Divide 11.47 in 2 so that weight and height can be added up to equal 11.47 in the end

5.73=0.08   5.73=0.13

71.68=W    44.07=H

<h3>Answer: B) Experiment</h3>

Reason:

Whenever you have two groups like this, one labeled the treatment group and the other the control group, we have an experiment gong on.

The treatment group gets the actual medication that is being tested. The control group gets a fake medication, aka placebo. Usually a placebo is meant for humans because it's more of a psychological factor. With cats, it likely won't affect them. However, such practices of having two groups like this is standard no matter what group of subjects you're testing.

The idea is that if the treatment group has better results compared to the placebo group, then it's likely the medication works.
