Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c )
Given
3y - 3x = 21 ( add 3x to both sides )
3y = 3x + 21 ( divide all terms by 3 )
y = x + 7 ← in slope- intercept form
First off.. we need to get the units the same. All in hours,
or all in minutes. 36 minutes = 36/60 hours = 3/5 hours = 0.6 hours.
12 minutes = 12/60 hours = 1/5 hours = 0.2 hours
Set up a proportion:
0.2 is to 0.6 as x is to 22.5
x/22.5 = 0.2/0.6
x = 0.2(22.5)/0.6
x = 7.5 hours
thanx
heyaaaaa
Here's a diagram showing how to combine angles LDA (in red) and angle ADE (in blue). Hopefully it becomes a bit clearer why these two angles add up to line segment LE. Erase the shared segment DA if it helps show LE better.
