(8/13+4/13)+(-6+8) < first one
(8/13+4/13)+(-6+8) and then you add the terms
Answer:
(3, 2 )
Step-by-step explanation:
Given the 2 equations
2x + y = 8 → (1)
y = - x + 5 → (2)
Substitute y = - x + 5 into (1)
2x - x + 5 = 8, that is
x + 5 = 8 ( subtract 5 from both sides )
x = 3
Substitute x = 3 into (2) for corresponding value of y
y = - 3 + 5 = 2
Solution is (3, 2 )

Answer:
I'm guessing you mean 10^4 = ?
Well, that equals 10 * 10 * 10 * 10
which equals 10,000
Step-by-step explanation:
Total miles= rate x time
We can set up 2 eq:
24=(x+8)(y-4)
24=xy
Where x is equal to my original rate
and y is equal to the original time spent traveling the 2mi
We can now solve for one of the variables and find our rate
