A skateboarder travels 2 km down the sidewalk moving faster and slower in certain areas. As he approaches a big hill he decides to just walk up the hill which was 1 km. He then gets back on his skateboard and heads home which is 2 km. The total time it took was 1.5 hours. What is the average speed of the skateboarder?

the answer is 8km I think because if the skatboard was there it had to travel fast so which makes it 8km

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.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
