There are 24 children at the skate park. Seven of them are on bikes, nine of them are on skateboards, and the rest are on inline skates (4 wheels per
skate). How many wheels are at the skate park?

82 wheels

Step-by-step explanation:

7(2) + 9(4) + 8(4) = x

14 + 36 + 32 = x

82 = x

64

Step-by-step explanation:

9 + 7 = 16

24 - 16 = 8 students on inline skates

8 x 4 wheels per skate = 32

32 x 2 shoes per person = 64

did you get the answer yet?

step-by-step explanation:

(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
