Answer:

Step-by-step explanation:

Remark

If you take 1 vertex of your 12-gon and draw lines (excluding the lines from the vertex you have chosen) to the 10 other vertices you get 10 triangles. Each triangle has 180 degrees.

The total number of degrees in the interior of the 12-gon is 180 * 10 = 1800

Each interior angle is 1800/12 = 150

There is a formula that you can make

180 * (# sides - 2) / # sides

if i have and 85 in my class and retook a test that i originally got a 72 what grade would i need for the average to be enough t
viktelen [127]
Assuming there is no specific percentages in the grade book, you would need a grade of 95 to get your whole grade to 90. You find this out by working backwards starting with 90 to find average. You take 90 times 2 which equals 180 and you subtract 85 from that to get 95! Brainliest?

Find the value of x in this equation. 25(4x − 3) − 2x = 45 − x
Charra [1.4K]

Answer:

x=40/33

Step-by-step explanation:

Let's solve your equation step-by-step.

25(4x−3)−2x=45−x

Step 1: Simplify both sides of the equation.

25(4x−3)−2x=45−x

(25)(4x)+(25)(−3)+−2x=45+−x(Distribute)

100x+−75+−2x=45+−x

(100x+−2x)+(−75)=−x+45(Combine Like Terms)

98x+−75=−x+45

98x−75=−x+45

Step 2: Add x to both sides.

98x−75+x=−x+45+x

99x−75=45

Step 3: Add 75 to both sides.

99x−75+75=45+75

99x=120

Step 4: Divide both sides by 99.

99x

99

=

120
