The interior angles of a triangle is equal to 180
So you add 45+55=100 then you subtract that from 180 which makes the other interior angle equal to 80 and because a flat line is also equal to 180 you subtract 180-80 which equals 100

So the answer would be 100

When 12 is added to a number the result is 32 less than 3 times the number.

sdas [7]

Let the number = x

12 + x = 3x - 32

x = 3x - 44 Subtract 12 from both sides

-2x = -44 Subtract 3x from both sides

x = 22 Divide by -2

Steven has some money if he spends nine dollars then he will have 3/5 of the amount he started with

Vesna [10]

Total money * fraction = part
$x* \frac{3}{5} =9 \\ ( \frac{5}{3}) * \frac{3x}{5} = 9* \frac{5}{3} \\ x= \frac{45}{3} =15$
