The ratio of the number of silver watches to the number of gold watches in a shop is 2: 3. which of the following best describes the number of silver and gold watches in the shop?

for every 2 silver watches, there are 3 gold watches.
for every 3 silver watches, there are 2 gold watches.
for every 2 silver watches, there are 5 gold watches.
for every 5 silver watches, there are 3 gold watches.

The Answer would be A

Step-by-step explanation: because 2:3 is 2 to 3.

(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
