Answer:

The answer to your question is: AC = 126

Step-by-step explanation:

Use the Thales' theorem

$\frac{140 - x}{81} = \frac{x}{9}$

9(140 - x) = 81x

1260 - 9x = 81x

1260 = 81x + 9x

1260 = 90x

x = 1260/90

x = 14

AC = 140 - 14

AC = 126

bonufazy [111]

Answer:

All answers are correct.

Step-by-step explanation:

Henry needs a total of 15 pints.

3 pints of yellow multiplied by 3 gives 9 pints of yellow, he needs 6 pints of red to get to 15, so he multiplies 2 pints of red by 3 to get 6 pints of red.

You add 9 + 6 to get the total of 15 pints he needs.
