(B) x = 40
Step-by-step explanation:
4x + 20 = 180
4x = 160
x = 40
Answer:
105 and 106
Step-by-step explanation:
x+(x+1)=211
2x+1=211
2x=210
x=105
Answer:
Infinitely Many Solutions
Step-by-step explanation:
Given
![\left[\begin{array}{cccccc}1&2&3&4&5&6\\7&6&5&4&3&2\\8&8&8&8&8&8\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccccc%7D1%262%263%264%265%266%5C%5C7%266%265%264%263%262%5C%5C8%268%268%268%268%268%5Cend%7Barray%7D%5Cright%5D)

Determine the type of solution
From the matrix, we have:
3 non-zero rows and 5 variables (the last column is the result)
When the number of variables is more than the number of non-zero rows, then such system has infinitely many solutions
i.e.


Answer:
37 sin 22 degrees = 12.53
use Pythagorean theorem
a^2 + b^2 = c^2
a^2 + 12.53^2 = 37^2
sqrt a^2 = sqrt 1,212
x = 34.8 or 35
