What is the value of y?
A. 50
B. 60
C. 30
D.40

The correct answer is D, y = 40

Step-by-step explanation: The first thing to note is the rule stating that sum of angles in a triangle equals 180 degrees. We have been given three angles which are, 2y, y+ 10 and 50.

If the sum of the angles in a triangle equals 180, then

2y + (y + 10) + 50 = 180

2y + y + 10 + 50 = 180

3y + 60 = 180

Subtract 60 from both sides of the equation

3y = 120

Divide both sides of the equation by 3

y = 40.

step-by-step explanation:

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
