PART OF A STUDY SET 1.)
What value of x makes the following equation true?

2(6 - 2x) - 2x = 2(5 + x) - 4

A) 3/4
B) 1/4
C) -1/4
D) -3/4

2.)

What is the solution to the following equation?

3(7 + 2x) + 3 = 3(5 + x) - 9(x + 1)

A) 3/2
B) 2/3
C) -2/3
D) -3/2

1.) A

2.) D

Step-by-step explanation:

1. 3/4

2.-3/2

Step-by-step explanation:

For the first problem, distribute the 2(6-2x) and 2(5+x) to simplify the equation.    This means, multiply what's inside the parentheses by 2. The simplified version of the equation is: 12-4x-2x=10+2x-4.

Once you have distributed, then combine like terms and solve for x.

You do the same thing for the second problem.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

c-   36

taxicab circle radius 9 has 4(9) = 36 points
