Peter solved the equation -3x - 5 = 1. His work is shown below. Explain whether or not Peter is correct.

Im sorry, you did not provide what peter did wrong. However, I will show you the steps to solve that problem below.

Step by Step:

−3x−5=1

Step 1: Add 5 to both sides.

−3x−5+5=1+5

−3x=6

Step 2: Divide both sides by -3.

−3x/ −3 = 6/ −3

x=−2

x=−2

the answer is 15% decrease

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'.
