Step-by-step explanation:
Given your ordered pair you would assume a = 5, b = 2
Set up both equations
5 + 2 = 7
7 = 7 (the numbers are equal so this correct)
2(5) - 8 = 2
10 - 8 = 2
2 = 2 (the numbers are equal so this is also correct)
Because both equations work with the ordered pair they <em>are</em><span> the solution of the given system.</span>
Answer: I think the answer is D
Step-by-step explanation:
Answer:
The cost to rent each chair and each table are $1.5 and $8.75 respectively
Step-by-step explanation:
Let x represent 1 chair
Let y represent 1 table
Therefore
3x + 2y = 22 ------------(1)
5x + 6y = 60 ------------(2)
Multiply (1) by 5 and (2) by 3
15x + 10y = 110 ----------(3)
15x + 18y = 180 ------------(4)
Subtract (3) from (4)
8y = 70
Divide through by 8
y = $8.75
Substitute y = 8.75 in (1)
3x + 2y = 22
3x + 2(8.75) = 22
3x + 17.5 = 22
Collect like terms
3x = 22 - 17.5
3x = 4.5
Divide through by 3
x =$1.5

Answer:
The manager's prediction is false
Step-by-step explanation:
Given
Jacob: 2000x + 4000
Carlos: 3500x - 40000
Required
Determine if both expression will be the same if x = 35
To do this;
Equate both expressions and then solve for x
i.e.
2000x+4000=3500x-40000
Collect Like Terms
2000x+4000=3500x-40000
-1500x=-44000
Divide both sides by -1500
Hence, the manager's prediction is not true because x
35
