Atire shop had to fill 2 1/2 tires with air. it took a small air compressor 2 1/2 seconds to fill them up. how long would it to take to fill 8 tires

A tire b had to fill 2 1/2 tires with air. It took a small air compressor 2 1/2 seconds to fill them up.The time taken to fill 8 tires is 8 seconds

Explanation:

Time taken by small air compressor to fill air in tires in a tire shop =    seconds

So, time taken by the small air compressor to fill air in 1 tire

=   divided by    

=

= 1 second

So, time taken by it to fill 8 tires = 8*1 seconds

                                            = 8 seconds

which is the the time taken to fill 8 tires

(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

the answer is a.
