6(2k-3) is the answer to this problem.
make a distributive
take the 6 out of the equation and u have remaining 2k-3. 6(2k-3)
Answer:
x = 19
Step-by-step explanation:
The two angles with measures are supplementary.
6x + 9 + 4x - 19 = 180
10x - 10 = 180
10x = 190
x = 19
You have to simplify like this
(-5)(-8)=40
There are an infinite number of different equations that have
x=2/3 as the solution, or as one of several solutions.
You didn't show us your list of choices, so we can't help you
pick the right one.
Just take each choice, one at a time. Write ' 2/3 ' in place of 'x'
in each equation, and simplify everything. You'll wind up with
one equation that's true, and the others will say something that's
nonsense.
The one that's true is the one that has x=2/3 as its solution.
