I’m not sure how to explain this problem but I can take another picture if it isn’t clear
rosijanka [135]

In order to determine the value of x, consider that one of the interior angles of the triangle is given by:

180 - (4x - 18)

= 180 - 4x + 18

= 198 - 4x

Next, consider that the sum of the interioir angles of a triangle is equal to 180:

(2x + 6) + 36 + (198 - 4x)

= 2x + 6 + 36 + 198 - 4x

= -2x + 240

this is equal to 180:

-2x + 240 = 180

-2x = 180 - 240

-2x = -60

x = 60/2

x = 30

Hence, the value of x is x = 30

Y+3=2(x+5), write the equation of the line in slope intercept form.
Alex

Answer:

slope intercept form: y=mx+b

y+3=2(x+5)

step 1: use distributive property

y+3=2(x)+2(5)

y+3=2x+10

step 2: subtract 3 on both sides to make y by itself

y+3=2x+10

-3 -3

final answer: y=2x+7

Which is the first step in solving<br> X-2 = 2?
Vanyuwa [196]

Answer:

The first step is to find a number that when subtracted from 2 gives you 2.

Step-by-step explanation:

The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so

first x-2=2, then x-2(+2)=2(+2)  which would give us,

x=4

*note: the parenthesis are just to show that we are adding the 2, to make it more understandable.
