Triangles add up to 180. So add up the two angles given, and subtract that from 180. That will be x!

The Mendes family bought a new house 6 years ago for $104,000. The house is now worth $177,000. Assuming a steady rate of growth

dusya [7]

Well, the house grew 73 k throughout the 6 years, so it grew around 12.16 k each year. 12.16/104= approximately 11.6923%
Rounded to the nearest 1/10 of a percent, it's 11.7%

30% of Number A is the same as 40% of Number B.

Goryan [66]

30% of number A means

$\dfrac{30A}{100}=\dfrac{3A}{10}$

similarly, 40% of number B means

$\dfrac{40B}{100}=\dfrac{2B}{5}$

These must be equal, so we have

$\dfrac{3A}{10}=\dfrac{2B}{5}$

Multiply both sides by 10 to get

$3A=4B \iff A=\dfrac{4B}{3}$

So, you can choose any number for A, and then you multiply it by 4/3 to get B. There are infinitely many solutions to this equation.

Please help me solve this LCM

hodyreva [135]

Note that

$x^2 - y^2 = (x - y) (x + y)$

and

$x^2 + 2xy + y^2 = (x + y)^2$

Then their LCM is $\boxed{x + y}$ .
