Lets use substitution, since there isn't any graphing method here.
y= x + 3
y = 2x - 1
x + 3 = 2x - 1
-x -x
x - 1 = 3
+1 +1
x = 4
Now solve for y
y = 2(4) - 1
y = 8 - 1
y = 7
We have the solution: (4,7)
<em><u>Answer:</u></em> Six hours and Twenty minutes.
<em><u>Step-by-step explanation: </u></em>The number before the : is the hours and the number after is the minutes, if you go even more in depth you will get to seconds and milliseconds.
Answer:
x = 36°
Step-by-step explanation:
Where a transversal crosses parallel lines, any obtuse angle it creates is supplementary to any acute angle it creates:
3x +2x = 180°
5x = 180° . . . . . . . . . collect terms
x = 180°/5 = 36° . . . . . divide by 5
