Answer:

Cost of a bag of chips is $0.75

Cost of a cheeseburger is $3.

Step-by-step explanation:

[Step 1] Let the cost of a cheeseburger be x.

[Step 2] Let the cost of a bag of chips be y

[Step 3] As it is given that x + y = 3.75

[Step 4] It is also given that 2x + 3y = 8.25

[Step 5] Multiplying the equation in [Step 3] by 2 and we get 2x + 2y = 7.50

[Step 6] Subtracting the equation in [Step 5] from the equation in [Step 4] we get y = $0.75

[Step 7] Therefore the cost of a bag of chips is $0.75

[Step 8] Substituting the value of y found in [Step 7]  into [Step 8] we get x = 3.

[Step 9] Therefore the cost of a cheeseburger is $3.

Check Answer:

Chip = 0.75

Cheeseburger = 3.00

Nathan Ordered one cheeseburger and one bag of chips for<u> $3.75.</u>

3.00 + 0.75 = $3.75

Hence, Chip = 0.75 and Cheeseburger = 3.00 is correct.

------------------------------------------------------------------------------------------------------

Chip = 0.75

Cheeseburger = 3.00

Jack Ordered two cheeseburger and three bags of chips for<u> $8.25.</u>

2 Cheeseburger = 3.00x2 = 6.00

3 bags of chips = 0.75x3= 2.25

6.00+2.25=$8.25

Hence,  Chip = 0.75 and Cheeseburger = 3.00 is correct.

The perimeter of the rectangle is 146 units. What is the length of the longer side?
NeTakaya

we know that

the perimeter of the rectangle is equal to

P=2W+2L

where

P is the perimeter of the rectangle

W is the width of the rectangle

L s the length of the rectangle

In this problem

P=146\ units \\ W=2x\\ L=3x+3

Substitute the values in the formula above

P=2W+2L\\ 146=2*(2x)+2*(3x+3)\\ 73=2x+3x+3\\ 5x=70\\ x=14\ units

W=2x=2*14=28\ units\\ L=3x+3=3*14+3=45\ units

therefore

the answer is

the length of the longer side of the rectangle is equal to 45\ units
