Answer:
C x=55
Step-by-step explanation:
the angles of a trianlge add up to 180
the unmarked angle is also 35 because of the same side length
35+35=70
180-70=110
BUT 2x=110 so x=55
P.S Can I get brainlist?
Answer:
Elimination isn't exactly the easiest for this situation. But since the equations are in the same form and not solved for the same variable, I would go with elimination. (If they were solved for the same variable, I would go with substitution.) It would require me to make a manipulation on both equations.
I would multiply first equation by 5 and second equation by -2. The reason I would do this is because the y's would have opposite coefficients and when you add opposites you get 0.
The new set of equations would look like this:
20x+10y=45
-14x-10y=2
But I will slope here since we aren't asked to solve it.
Some texts use the term linear combination instead of elimination. They are the same.
The way i did that in middle school was plot the points then find the slpoe and work it out from there
Answer:
It's 2
Step-by-step explanation:
X is 2 because if you multiply two by two you get 4
Yes, because if it has brackets, it just means it is an absolute value
