How much medicine should he add to the food?​
quester [9]

Answer:

Paul should give 18 teaspoons of medicine to his dog.

Step-by-step explanation:

It is stated in the question that for every 12 pounds, 3 teaspoons of medicine is to be given to the dog.

This implies that:

12 pounds = 3 teaspoons

1 pound = 3/12 teaspoons

             = 1/4 teaspoons                      <em> ( by cross multiplication )</em>

<em />

<h3>72 pounds = 1/4 * 72 teaspoons</h3><h3>                   = 18 teaspoons</h3><h3 />

Hence, Paul should add 18 teaspoons of medicine to his dog's food.

Does anyone know the answer?
azamat

Answer:

1=163 degrees

2=×=10 degrees

3=×=3

Step-by-step explanation:

54x+1+9x-10=180 we are using this expression because alternate angles add up to 180 degrees

54x+9x+1-10=180

63x-9=180

63×=180+9

63×=189

63×÷63×=189÷63×

X=3

Angle in bold print is (54x+1)

54×3=162

162+1=163 degrees

No.2 Find x

7x+35+x+65 =180

7x+x+35×65=180

8x+100=180

8x=180-100

8x=80

8x÷8x=80÷8

X=10 degrees

No.3 Find x

54x+1+9x-10=180

54x+9x+1-10=180

63x-9=180

63x=180+9

63x=189

63x÷63x=189÷63

X=3
