<h2>Answer :—</h2>

‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\sf{\longrightarrow x = 20}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎

$\begin{gathered}\rm{ \underline{ \underline{ \red{Given}}}}\begin{cases}\sf{m||n} & \\ \\\sf{a\:transvey\:l\:passes\: through\:m\:and\:n}& \\ \\ \sf{two \:angles = (7x-3)°\:and\:(6x+17)°}&\end{cases}\\\\\end{gathered}$

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀⠀

➠ Using the property of adjacent angles and vertically opposite angles , we have :

‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\sf{\longrightarrow (7x-3)=(6x+17)}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎

‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\sf{\longrightarrow 7x-3-6x-17=0}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎

‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\sf{\longrightarrow 7x-6x-3-17=0}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎

‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\sf{\longrightarrow x-20=0}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎

‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\sf{\longrightarrow x=20}$

Converting observations from original values to standard deviation units is known as

Tju [1.3M]

Converting observations from original values to standard deviation units is known as standardizing the data values. This is done in order to get values in such a form where we can compare them. For example, if we have the test scores of two different school and we want to compare the result of the students we have to first convert them into standard deviation units.

Converting the values to standard deviation units is also known as converting the values to z scores.

The formula for the z score is:

[tex]z= \frac{x-u}{s} [/tex]

where x is the data value, which is to be standardized.
u is the average of the entire data.
s is the standard deviation of the data.

Plz help this is due tonight

tatuchka [14]

Answer:

7. Answer is 1236.25$

8. Answer is 143.75$

9. Answer is 16.485$

10. Answer is 6.825$

11. Answer is 31.25%

12. Answer is 0.125 for the decimal section and 12.5% for the percent section.

Step-by-step explanation:

7. 7.5 percent of 1150 is 86.25 and 86.25 + 1150 is 1236.25.

8. 15 percent of 125 is 18.75 therefore 125 + 18.75 is equal to 143.75.

9. 3.50 + 2.25 + 9.95 + 15.7 and 5 percent of 15.7 is 0.785 and 15.7 + 0.785 is 16.485.

10. 4.25 plus 2.25 is 6.50 and 5% of 6.50 is 0.325 and 6.50 plus 3.25 is 6.825.

11. 63 plus 25 is 88 so 88 is 68.75 percent of 128 and 100 minus 68.75 is 31.25 so 31.25 is the answer.

12. 1/8 is 12.5 percent so for the percent section it is 12.5 and for the decimal section 0.125

What's the solution of -x+y=1 x+y =11 using elimination of addition and subtraction

mafiozo [28]

Answer:

x=5

y=6

Step-by-step explanation:

If you add the two, it turns into 2y=12. That means y=6. So then x would equal 5 if you bring y into one of them.
