Answer:
C 40
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
y+10 + 2y + 50 = 180
Combine like terms
3y + 60 =180
Subtract 60 from each side
3y+60-60 = 180-60
3y = 120
Divide by 3
3y/3 = 120/3
y = 40
Answer:
X=-0.9375 or -15/16
Step-by-step explanation:
-0.6+0.9=x+2.4
-0.6x-x=2.4-0.9
-1.6x=1.5
x= -0.9375
False it only works if it has a 0 in example 1.50 then you could
2 + 2 =4 is four tgvjixyi9
