Answer:

x=16

Step-by-step explanation:

y = 1/2 x -3

Let y =5

5 = 1/2 x -3

Add 3 to each side

5+3 = 1/2 x -3+3

8 = 1/2x

Multiply each side by 2

8*2 = 1/2x*2

16 =x

Answer: 16

<u>Step-by-step explanation:</u>

$.\quad y=\dfrac{1}{2}x - 3\\\\\\.\quad 5=\dfrac{1}{2}x - 3\\\\.\ \underline{+3}=\underline{\ \ \quad +3}\\\\.\quad 8 =\dfrac{1}{2}x\\\\(2) 8 =(2)\dfrac{1}{2}x\\\\.\quad 16 = x$

Using the diagram below, find x.

Alona [7]

Answer:

$x=28$

Step-by-step explanation:

$we~know~ that~ all~ the~ angles ~in ~a ~triangle ~all~add ~up ~to ~180$ ° $That ~means: x + ( 2x + 5 ) + ( 3x + 7 ) = 180.~Since~ addition~ is~ associative,\\~x + ( 2x + 5 ) + ( 3x + 7 ) = 180~ is ~the~ same ~as~ x + 2x + 5 + 3x + 7 = 180.$

$Combining~ like~ terms,~ we ~get: 6x + 12 = 180.$

$After~ we ~move~ 12~ to~ the~ other~ side~ so ~the~ x~ is~ iscolated,~ we~ get:\\\ 6x = 168.\\$

$Dividing~ each~ side~ by~ 6 ~gets~ us ~to~: x = 28, ~so ~the~ answer~ to~ this~ question~ is D.\\$

$Hope~this~helps!~Have~a~blessed~day~ahead!$

Graph the system of equations on your graph paper to answer the question

UNO [17]

Since we have to solve this system graphically, we'll have to draw both lines.

To draw a line, simply build a little tables with two x,y values: for the first line we have

$\begin{array}{c|c}x&-x+3\\0&3\\1&2\end{array}$

So, you can draw the points (0,3) and (1,2), connect them, and you'll have the graph of the line $y=-x+3$

For the second line we have

$\begin{array}{c|c}x&x+5\\0&5\\1&6\end{array}$

So, you can draw the points (0,5) and (1,6), connect them, and you'll have the graph of the line $y=x+5$

Finally, we have to check where the two lines cross. If your drawing is accurate enough, you'll see that the point you're looking for is (-1, 4)

If MNLP, then 2 _____ 3. Choose the relationship symbol to make a true statement. < > =

storchak [24]

Answer:

The answer is > (greater than)

Step-by-step explanation:

It is > because if MN is the larger side and the largest angle would be across from the largest side, then that would make the largest angle, angle 2 and that would in turn make 3 the smaller angle. I know this is correct because I got it right.
