The college student spends 45 dollars on laundry.
To find this you have to divide 495, by 11. This is because the question states "the college student spends 10 times more on pizza than laundry", which means the cost of the laundry (l) is added to the cost of pizza (10p). Dividing 495 by 11, you get 45.
As I stated earlier, the cost of laundry is added to the cost of pizza. 45 * 10 is 450. 450 + 45 = 495. Thus making 45 the answer.
I hope this helps!
Three lines creating six angles
3 angles on top, 3 angles below
Since the top left angle is a right angle
It means the line that divides the top angles from the angles below is bisected by a perpendicular line.
This means the sum of the angles of the top left = 90°
Therefore, x + 61° = 90°
x = 90° – 61°
x = 29°
