Find x. Give reasons to justify your solution.

stich3 [128]

Answer:

x = 28

Step-by-step explanation:

If AB and CD are the straight lines, sum all the angles formed at a point lying on this line will be 180°.

m∠COE + m∠EOF + m∠FOB + m∠BOD = 180° [Angles at a point O on line AB]

3x + x + (x + 12) + m∠BOD = 180°

m∠BOD = 180° - (5x + 12)

Similarly, m∠AOD + m∠AOC = 180°

152° + m∠AOC = 180°

m∠AOC = 28°

Since, ∠AOC and ∠BOD are the vertical angles,

m∠AOC = m∠BOD

180° - (5x + 12)° = 28°

5x + 12 = 180 - 28

5x = 140

x = 28

A store sells packages of pencils.which package offers the best unit price

tiny-mole [99]

The details of the packages are not posted, however I can tell you how to find the answer.

First determine how many pencils are in each pack.
Then divide the price of the pack by the number of pencils to find out which pack has the least cost per pencil. To put this in equation form:
$\frac{Cost}{Pencils}$

Whichever pack has the least cost per pencil is the one that is the best priced.

Which of the following are functions? x=-3 y=10 3x+2y=3

choli [55]

Y=10 and 3x+2y=3

X=-3 is NOT a function because it has multiple y values for one x value.

Y equals ten is a horizontal line, and passes the vertical line test, as does the third equation
