What is the value of y? enter your answer in the box

The value of Y is 5.

Step-by-step explanation:

I am assuming you're asking of this particular question?

If so, start out by creating a theory that if both sides of the triangle are marked as "equal" with one mark, then both angles of B and C should be equal as well. So, in other words, 75 = (3x). Or, in more simpler terms, 75 = 75.

With that in mind, we'll now add all angles to equal 180 since this shape is a triangle. 75 + 75 + (4y+10) = 180.

Add similar terms, 150 + (4y+10) = 180.

Subtract 150 from both sides; (4y+10) = 30.

Subtraction Property of Equality (Subtract 10 from both sides); 4y = 20.

Finally, divide both sides by 4. Y = 5.

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
