Plan A = 10x + 144
Plan B = 48 + 22y
Equate them
10x + 144 = 22y + 48
22y - 10x = 144 - 48
22y - 10x = 96
divide by 2
11y - 5x = 48
What I did was just use trial and error at this point.
11(8) - 5(8) = 48
8 visits must a person make for plan A to plan B.
Hello from MrBillDoesMath!
Answer: x = -1
Discussion:
Let x be the unknown integer. Then
5
x^2 + 3x = 2 or
5x^2 + 3x -2 = 0 or (factoring)
(x+1) ( 5x -2) = 0
so x = -1 (the other value of x, +2/5, is not an integer)
Thank you,
MrB
Answer:
since 4y=12 and 4y=2x then 4y=12=2x or 12=2x
Answer:
84+n=342
Step-by-step explanation:
you would subtract 84 from 342 to find the width since it is perimeter.
Answer: If two pair is parallel then it has no solution.
Step-by-step explanation:
Since we have given that
Let the number of gained yards by each player be y
For the case of Brayden:
Equation will be

For the case of Howard :
Equation will be

For the case of Vincent :

Since First two equations are parallel so it has no solution.
Reason:

Hence, if two pair is parallel then it has no solution.
