3-120 (a) More Solving By Rewriting Sean was trying to solve for x in the equation
0.4(x - 2) = 3.4 -0.2x. He said to his teammate,
April, “Decimals! I wish that we only had equations with
whole numbers!" Suddenly, April blurted out, "Wait,
Sean! I think there is another way. Can't you first
rewrite this equation so it has no decimals? Then it will
be faster and easier to solve!"
What is April talking about? Explain what she means.
Then rewrite the equation so that it has no decimals.

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

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'.

answer: 7

step-by-step explanation:

there are infinitely many solutions.
