Answer:
It would take 50 minutes
Step-by-step explanation:
<u>Distance, velocity and time</u>
The speed is the rate at which the distance changes with respect to time. If x is the distance, t is the time, the speed v can be obtained by
We know the trip takes 40 minutes when traveling at 50 miles/hour. The distance can be determined by isolating x in the above equation
The given time is expressed in minutes, we need to convert it to hours. 40 minutes is 
. The distance is
If the speed was 40 miles/hour, the same distance would be covered in t hours, taken from the above equation as
The figure is a right angle
Complementary = sum of 90 degrees
35 + 2x - 5 = 90
30 + 2x = 90
2x = 60
Solution: x = 30
11 5/6 as a decimal would be 11.83. Then, rounding that to the nearest whole number would be 12. Giving you an answer of 12.
Y=-4.5 and x=-2
So your first “equation equals to x so then you substitute the X in the second equation with the first equation. Which would give you 3(2y+7)-2y=3 then you solve (make sure to distribute). Which would give you y=-4.5 Can you substitute your y answer in your first equation. Which would be x= 2(-4.5)+7 then your solve
