Answer:
System of equations:
L = 5W + 7
2W + 2L = P
L = 62 cm
W = 11 cm
Step-by-step explanation:
Given the measurements and key words/phrases in the problem, we can set up two different equations that can be used to find both variables, length and width, of the rectangle.
The formula for perimeter of a rectangle is: 2W + 2L = P, where W = width and L = length. We also know that the L is '7 more than five times its width'. This can be written as: L = 5W + 7. Using this expression for the value of 'L', we can use the formula for perimeter and solve for width:
2W + 2(5W + 7) = 146
Distribute: 2W + 10W + 14 = 146
Combine like terms: 12W + 14 = 146
Subtract 14 from both sides: 12W + 14 - 14 = 146 - 14 or 12W = 132
Divide 12 by both sides: 12W/12 = 132/12 or W = 11
Put '11' in for W in the equation for 'L': L = 5(11) + 7 or L = 55 + 7 = 62.
(_ , _) means (X , Y)
(25 , ) means
X = 25 then you need find the value of Y from the equation .
so the first answer is (25,-3)
..............
( , -8) means
Y = -8 then you need to find the value of X from the equation .
so the second answer is ( 0 , -8 )
hope this would help you
Answer:
.
Step-by-step explanation:
.
1. You can call 
to the cost of each one of Tanya's items and 
to the cost of each one of Tony's items.
2. Based on the information given in the problem and knowing that both paid the same amount of money, you can write the following expression:
3. You must solve for :
4. The total amount of money that Tanya and Tony paid was:
dollars
5. Therefore, the amount of money that Tony paid for each item was:
dollars
The answer is: The individual cost of each Tanya's items is 
dollars and the individual cost of each Tony's items is 
dollars.
