Answer:
x= -8
collect like term than divide both sides
6x-4x = -20+4
2x= -20+4
2x=-16
x= -8
I don't like these algebra problems which pretend to be geometry.
These are supplementary angles adding to 180 degrees; geometry done.
7x - 1 + 3x - 9 = 180
10 x = 190
x = 19
ABC=3x - 9 = 3(19) - 9 = 48
Answer 48°

Answer:
$40
Step-by-step explanation:
Let the original price of the item be x.
From the first statement, the price of the item was reduced 25% to $30. This means that new price of the item is now 75% (0.75) of the original price(x), and this new price is equal to $30. i.e
0.75x = 30
Now, let's solve for x.
0.75x = 30 [divide both sides by 0.75]
=
x = 40.
Therefore, the original price of the item was $40
