The sum of 5 is equal to 8 less than 6 times y

Given data: The sum of 5 is equal to 8 less than 6 times y

Let us convert algebraic expression into equation.

5 = 6 × y – 8

⇒ 5 = 6y – 8

⇒ 5 + 8 = 6y  (Add 8 on both sides to equal the expression)

⇒ 13 = 6y

⇒   (Divide 6 on both sides to equal the expression)

⇒ y = 2.166

Hence the answer is 2.166.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
