Answer: it will take 2.5 hours for both people to meet after person B leaves.
Step-by-step explanation:
The distance between the house of person A and his cousin's house is 234 miles.
At the point where they meet, they would have travelled 234 miles.
Person A travelled at an average speed of 44 miles per hour.
Let t represent the time spent by Person A in travelling from his house to the point where they meet.
Distance = speed × time
Distance covered by person A would be
44 × t = 44t
One and half hours later, person B leaves his house to visit person A, travelling at an average speed of 62 miles per hour. This means that total time spent by person B in travelling to the point where they meet is (t - 0.5) hours. Distance covered would be
62(t - 0.5) = 62t - 31
Since the total distance covered is 234 miles, then
44t + 62t - 31 = 234
106t = 234 + 31 = 265
t = 265/106 = 2.5 hours
Answer:
190 inches
Step-by-step explanation:
(15x12)+10=190
0 is the starting pointing for equations that are for positive numbers. 0 sets an easy way to figure out problems that have negatives. 0 is important to solve any problem with integers, and decimals!
Answer:
-14
Step-by-step explanation:
[(-11) + (-5)] + [3 + (-1)]
= (-11 - 5) + (3 - 1)
= (-16) + 2
=<u> -14 </u>
Answer
(a)
(b)
Step-by-step explanation:
Remember that when you want to solve a problem like this, you express the equation as following
So, if you know the inverse of 
then
For this case
Now for this case the inverse of A would be
Then when you multiply with the vector solution
So from that information you can conclude that the solution to the system of equations is x = 500/7 y = 2400/7 and z = 2700/7
