Need our teacher never taught my class this and its on our homework. someone ! i'll give brainliest to whoever is right

Step-by-step explanation:

The reason this is titled "Mathematical Connections" is because you're supposed to draw upon all of the things you have learned about angles and equations and put them together to solve this problem. No problem-specific teaching should be necessary.

__

The words and diagram tell you that ...

  m∠ABX + m∠CBX = 92°

They also tell you that ...

  m∠CBX = y°.

The words tell you that m∠ABX = 12° + 4(m∠CBX). Since m∠CBX = y°, this means ...

  m∠ABX = (12 +4y)° . . . . . this expression fills the box on the diagram

__

So, we have expressions involving y for each of the parts of angle ABC. We can substitute those expressions into the angle sum equation to get

  (12 +4y) + (y) = 92 . . . . . . dropping the degree symbol, using only numbers

__

Using what you know about algebra and 2-step equations, you can solve this to find the value of y.

  5y +12 = 92 . . . . . simplify

  5y = 80 . . . . . . . . subtract 12

  y = 16 . . . . . . . . . . divide by 5

This value can be substituted back into the expressions for angle measure:

  m∠CBX = y° = 16°

  m∠ABX = (12+4y)° = (12 +4·16)° = 76°

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
