The answers are:

a = c

c = d

b + d =180 degrees

Here's how:

When a line intersects two parallel lines, then corresponding angles are formed which means the same corners are congruent.

option c = d is considered.

And, because of vertical angles,

a = d is also an answer.

Using the information in part A, interpret the meaning of the quotient in terms of the two fractions given
Sophie [7]

Answer:

hello the information in part A is missing below is the missing information

How many 2/3 foot pieces can Wendy cut from the 5 and 1/3 feet of ribbon? Show your work

answer :  8

Step-by-step explanation:

The quotient in terms of the two fractions

Determine 2/3 foot that can be gotten from 5 1/3

Divide  5 1/3  by 2/3  ( how to get quotient )

= 5 1/3 / 2/3

= (16 / 3 ) / ( 2/3 )  ( meaning of the quotient )

= 8

The system of equations is given:
Nutka1998 [239]

Answer:

x=-1/85; y=-283/85; z=2/17

Step-by-step explanation:

Using an algebraic method like elimination or substitution would take a lot of steps which could lead to mistake the calculations. In this case, I decided to use the Gaussian elimination. We can express the system in matrix form as follows:

\left[\begin{array}{ccc}2&-4&6\\9&-3&1\\5&0&9\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}14\\10\\1\end{array}\right]

To begin the calculations, we write the system in augmented matrix form and use the Gaussian elimination:

\left[\begin{array}{ccccc}2&-4&6&|&14\\9&-3&1&|&10\\5&0&9&|&1\end{array}\right]

By applying the Gaussian elimination, the final matrix is the following:

\left[\begin{array}{ccccc}1&0&0&|&-1/85\\0&1&0&|&-283/85\\0&0&1&|&2/17\end{array}\right]

In order to verify the results, it´s enough to substitute the calculated values in the original equations to see if the equalities are correct. Here you can see the verification for all of the equations:

2(-1/85)-4(-283/85)+6(2/17)=14\\9(-1/85)-3(-283/85)+1(2/17)=10\\5(-1/85)+9(2/17)=1

Simplify -2 1/6 - ( -7 1/3 )
givi [52]

Answer:

5 1/6

Step-by-step explanation:

Note that - ( -7 1/3) = 7 1/3.  The two ' - ' signs cancel each other.

Thus, the original expression becomes -2 1/6  +  7 1/3.

Here the LCD is 6.  We re-write the above expression as -2 1/6 + 7 2/6.

Reversing the order of these terms makes the work a bit easier.

7 2/6 - 2 1/6 comes out to 5 1/6
