Answer:
x = 3
Step-by-step explanation:
Solve for x:
1/2 + 1/x = 5/6
Bring 1/2 + 1/x together using the common denominator 2 x:
(x + 2)/(2 x) = 5/6
Cross multiply:
6 (x + 2) = 10 x
Expand out terms of the left hand side:
6 x + 12 = 10 x
Subtract 10 x + 12 from both sides:
-4 x = -12
Divide both sides by -4:
Answer: x = 3
Exact Form:
-31/4
Decimal Form:

Answer:
Step-by-step explanation:
Perform the indicated multiplication first:
25000 - 500bx + 50ax - abx²
It would seem that this should be part of an equation, and that the other part is missing; without another part, there's no way to determine the values of a and b. Please ensure you have copied this problem down completely.
