A straight line is 180°, so you add these two angles together because they make a straight line:
3x° + 75° = 180°
To find "x", isolate/get the variable "x" by itself in the equation. Subtract 75° on both sides
3x° + 75° - 75° = 180° - 75°
3x° = 105° Divide 3 on both sides to get "x" by itself
x = 35°
PROOF
3x° + 75° = 180° Substitute/plug in 35 into "x" since x = 35°
3(35)° + 75° = 180°
105° + 75° = 180°
180° = 180°
For number 8. spencer finished more, the common denominator is 40. so spencer finished:30,40 and simone:16/40
It would be B. because the rise over run is 31.25 over 5 which is divided to 6.25 which is rounded to 6.3
Answer:
Step-by-step explanation:
hello :
an equation for the line A is : y-14 = 3(x-2) or y = 3x +8
an equation for the line B is : y-23 = 3(x-5) or y =3x +8
same line
C. The system of equations has an infinite number of real solutions.
note : same slope means parallal or identical
