Answer: 1 hour
Step-by-step explanation:
(60-50) * 5 = 50 miles more than planned.
50 miles planned to drive in 1 hour.
So he drove 1 hour faster.
Answer:
first number= 19/5
second number= 2/5
Step-by-step explanation:
first number= a
second number= b
a+3b=5 equation 1
b+2a=8 equation 2
using equation 2 we have
b=8-2a
using equation 1 we have
a+3(8-2a)=5
a+24-6a=5
24-5=6a-a
19=5a
a=19/5 = first number
so using b=8-2a
we have
b=8-2(19/5)
b=8-(38/5)
b=2/5 = second number
Remember a negative sign before the ( ) changes all the signs of the terms in the ( )
2.74 + 3.5= 6.24
This is easy if you know the rules
Hope this helps

Answer:
We conclude that the point of intersection i.e (x, y) = (-2, -5) will appear to be the solution to the system of equations.
Step-by-step explanation:
We know that when two lines meet or intersect at a point in the coordinate plane, the point where they meet is called the point of intersection.
The point of intersection is termed as the solution of the system of equations on a coordinate plane.
Given that the two lines intersect at (-2, -5)
In other words,
Thus, the point of intersection = (x, y) = (-2, -5)
Thus, we conclude that the point of intersection i.e (x, y) = (-2, -5) will appear to be the solution to the system of equations.
