Answer: x-2
Step-by-step explanation:
Given
4(x-2)-3(x-2)
Distributive property
=4x-8-3x+6
Move the like terms together
=4x-3x-8+6
combine like terms. REMEMBER you need to change signs if it is negative signs outside
=x-(8-6)
Simplify
=x-2
Hope this helps!! :)
Please let me know if you have any question.
So because it was $5 off, and she paid 80% of the original price, that would mean it would have been 20% off. That means 20% = $5. Multiply that by 5 to get to 100% and you find that the shirt is $25 originally. Then you can either multiply that 20% = $5 by 4 to get 80%, or just subtract $5 from the full price. That means Selina paid $20 for the shirt.
It looks like we're told that



We use the fact that
is linear to find
. First, we notice that

We also have


So once we find
, we can determine
and
. We have

and using this we find


Then


The answer is B, because to circumscribe a quadrilateral the sum of each two opposite angles must be 180
