122 degrees because you have to add both of them together to get the answer so just turn the negative number into a positive number and answer it like that
<u>Answer:</u>
The correct answer option is 'both Adler and Erika solved for <em>k</em> correctly because either the addition property of equality or the subtraction property of equality can be used to solve for <em>k</em><em>'.</em>
<u>Step-by-step explanation:</u>
Both Adler and Erika have solved for <em>k</em> correctly since both the properties, addition property of equality and subtraction property of equality, can be to solve for <em>k.</em>
The fraction 
has to be subtracted from both the sides so even if it is added, the negative sign still would make it subtracted from both the sides.
Answer:
7. 30° 8. 97.5° 9. 90° 10. 55° 11. 100° 12. x=32° y=64°
Answer:
Step-by-step explanation:
first step: 0.5 * x
second step: 3* (0.5x) = 1.5x
third step: (1.5x)^2
fourth step: (1.5x)^2 + 1 = 50
(1.5x)^2 + 1 = 50 Subtract 1 from both sides
(1.5x)^2 = 49 Take the square root of both sides
1.5x = sqrt(49)
1.5x = +/- 7
1.5x = +7
x = 7/1.5
x = 4.67
1.5x = - 7
x = - 7 / 1.5
x = - 4.67
