Eli made fancy blue costume decorations for each of the dancers in his year-end dance performance. He used 1/10 of a meter of ribbon for each decoration, which he got by cutting 1/5 of a meter of ribbon into equal pieces. How many decorations did Eli make?

There are 2 decorations that Eli makes.

Step-by-step explanation:

Since we have given that

Length of a meter of ribbon used =

Length of a meter cut into equal pieces =

So, Number of decorations that Eli make is given by

Hence, there are 2 decorations that Eli makes.

(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
