If solving a system of linear equations by elimination or substitution I get that 0=0, as final or intermediate step depending o

aniked [119]

Answer:

If I get 0=0 then it means:

If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutions
If the system of equations is 3 linear equations in 3 variables, there might be infinite number of solutions

Step-by-step explanation:

Linear equation systems can consist of two or three equations with two or three unknowns respectively.

A system of linear equations in two variables has infinite solutions when the lines made by them overlap each other and similarly a system with three variables has infinite solutions when two lines overlap each other and third plane is parallel to them

Hence,

If I get 0=0 then it means:

If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutions
If the system of equations is 3 linear equations in 3 variables, there might be infinite number of solutions

You have three $1 bills, four $5 bills, and two $10 bills in your wallet. You select a bill at random. Without replacing the bil

<h2>Greetings!</h2><h3>To find the first probability, you first find the amount of $10 bills and the total amount. Then you can put this into a fraction:</h3>

$\frac{2}{9}$

<h3>Now, do the same but for the total amount, be sure to remove 1 because you have not returned the first one picked. Now find the amount of $1 bills too:</h3>

$\frac{3}{8}$

<h3>Now you have two fractions of two consecutive events, now just simply multiply the two together:</h3>

$\frac{2}{9}$ x $\frac{3}{8}$ = $\frac{6}{72}$

<h3>Now as both numbers are factors of 6, both can be divided by 6 to get a simplified probability:</h3>

$\frac{6}{72}$ ÷ 6 = $\frac{1}{12}$

<h3>So P($10 then $1) = $\frac{1}{12}$ </h3>

Find each lettered angel measure

hammer [34]

Answer:

a = 64°

b = 138.7°

Step-by-step explanation:

First, Let's find the measure a,

180° = 116° + a
180 - 116 = a
a = 64°

______

Now,

90° + a + 82° + x + x + x = 360°
90+ 64 + 82 + 3x = 360°
236 + 3x = 360
3x = 124/ 3
x = 41.3°

______

Now that we found out what x equals, let's find 'b'-

b + x = 180°
b + 41.3 = 180
b = 180 - 41.3
b = 138.7°
