180 - (x+3) = 2x - 6
180 + 6 = 2x + x +3
183 = 3x
x = 61
Proof:
The 2 angles should equal to 180°.
61 + 3 = 64°
2(61) - 6 = 116°
64 + 116 = 180°
Therefore x is 61°.
A and C are the answers. Vertical angles are opposite angles made from the same 2 crossing lines.
There are two equations that we could write.
[Division]
-> Divide total money spent by price per ticket, set it equal to <em>j</em>
<em>j</em> = 30 / 5
[Simplifed slope-intercept]
-> Multiply the price per ticket by <em>j</em> and set the equation equal to the total money spent
30 = 5<em>j</em>
Answer:
x = mp - np
Step-by-step explanation:
m = n + x/p; multiply by p
mp = np + x; move terms
x = mp - np
