Um time de futsal marcou 60 gols, correspondendo a quatro sextos do total de gols do campeonato. Quantos gols foram marcados no campeonato?

Step-by-step explanation:

The given question is

A futsal team scored 60 goals, corresponding to four-sixths of the league's total goals. How many goals were scored in the league?

If 60 goals represents four-sixths of the total goals, then how many goals were scored?

Here we need to use the rule of three, where the given equivalence is

And the total number of goals is represents by 1, which is the 100% of goals.

Therefore, the team scored a total of 90 goals.

(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
