Answer:

one solution.: -6.5

Step-by-step explanation:

First you start with the side with parenthisis. So you multiply 7xY= 7y and then you multiply 7x3= 21 so you get 7y + 21 = 5y + 8

Second you subtract 8 from both sides.

7y + 21 = 5y +8

-8 = -8

wich leaves you with 7y + 13 = 5y

Next you want to subtract 7y from 5y because you cant have a variable on both sides. 7y + 13 = 5y

-7y + 13 = -7y which will leave you with 13= -2y

Now you divide each number by -2 to get "y" by itself.

13/-2 = -6.5 = y

Answer:

True Postulates are used to prove theorems.

True Two points determine a line

Step-by-step explanation:

A postulate, in mathematics, is a numerical property that cannot be directly proven, but it is still present, and no has exceptions. Postulates are often used to prove theorems, particularly in geometry. An example of this can be found in the midsegment theorem which states that the average of the two bases in a trapezoid gives the length of the midsegment. Depending on how one chooses to prove this, one could potenitally need the Parts-whole Postulate theorem. Thus, one can state that Postulates are used to prove theorems.

A line can be drawn to connect any two given points. Therefore, one can states that two points determine a line, as only two points are needed for one to draw a line between them.
