Answer:-1/6
Step-by-step explanation:
-1/2 + (3/4times4/9)
-1/2 + (3/4 x 4/9)
-1/2 + (3x4)/(4x9)
-1/2 + 12/36
(18 x -1 + 1 x 12)/36
(-18+12)/36
-6/36=-1/6
1. 504=3x
x=168
2. 64=20m
m=3.2
Answer:
138.2degrees
Step-by-step explanation:
178.2 - 40 = 138.2
Solve for x:
x^2 + 10 x + 12 = 36
36 = 36:
x^2 + 10 x + 12 = 36
Subtract 12 from both sides:
x^2 + 10 x = 24
Add 25 to both sides:
x^2 + 10 x + 25 = 49
Write the left hand side as a square:
(x + 5)^2 = 49
Take the square root of both sides:
x + 5 = 7 or x + 5 = -7
Subtract 5 from both sides:
x = 2 or x + 5 = -7
Subtract 5 from both sides:
Answer: x = 2 or x = -12 Thus the Answer is A.
