2+2 will equal 4 because if you get two pencils and 2 more pencils it will equal 4
Answer:
x= 20
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
The first angle is 3x+40 and the second angle is 80. The add together to form a straight line. The straight line is 180 degrees.
3x+40 + 80 = 180
Combine like terms
3x+120 = 180
Subtract 120 from each side
3x+120-120=180-120
3x = 60
Divide each side by 3
3x/3 = 60/3
x = 20
Answer:
x = 2
Step-by-step explanation:
At the point of intersection f(x) = g(x), thus
10x - 6 = x + 12 ( subtract x from both sides )
9x - 6 = 12 ( add 6 to both sides )
9x = 18 ( divide both sides by 9 )\
x = 2 ← at point of intersection
