Answer:
Johnny and his family left home at 10:00.
Step-by-step explanation:
First, You add all of the minutes up,
45+20+10= 75
Then convert the minutes to hours,
75 mins = 1 hr and 15 mins.
Add the hours together,
1 hr + 2 hrs = 3 hrs
Then add minutes,
3 hrs and 15 minutes
Subtract 3 hrs and 15 mins from 13:15,
13.15 - 3.15 = 10:00
Your answer is:
Johnny and his family left home at 10:00.
Answer:
m∠7 = 140º
Step-by-step explanation:
m∠4 = m∠2 + m∠3
120 = 80 + m∠3
m∠3 = 40
m∠3 + m∠7 = 180
40 + m∠7 = 180
m∠7 = 140º
slope-intercept formula: y = mx + b
m = slope
b = y-intercept
your equation: y = 4/3x - 3
m = 4/3
b = -3
so, the answer would be the last option.
hope this helps, have a great day/night :)
