I thought of a number, double and add fifteen the result is 45. What is the equation to represent to the statement?

The answer is 15

Step-by-step explanation:

if you double 15 it becomes 30, and if you add 15 to 30 that becomes 45.

Thus, 15 is the answer.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
