Solve for x
2x+3y=9
2x=9-3y
2x/2 = 9-3y/2
X=9-3y/2
Solve for Y
2x+3y=9
3y=9-2x
3y/3 = 9-2x/3
Y=9-2x/3
Y=-2x/3 + 3

Answer:
She would pay $36.36 to cover the whole box.
Step-by-step explanation:
You need to find the area of all sides of the box and add them together first.
So, 8x6 = 48
48x2 = 96 (Two of the same sides)
6x11 = 66
66x2 = 132 (Two of the same sides)
8x11 = 88
88x2 = 176 (Two of the same sides)
Add all of those together to get 404 sq inches.
Multiply 404 x 0.09 (the 9 cents) to get your answer of $36.36! Hope this helped!
We have to calculate the total cost of the meal. We know that Adam ( A ) and his dad ( D ) share the cost of the meal in the ratio 2 : 3 and that Adam`s dad pays 52.20 Pounds. So A : D = 2 : 3; A : 52.20 = 2 : 3. Using the cross products, A * 3 = 2 * 52.20; A * 3 = 104.40; A = 104.40 : 3; A = 34.80 Pounds. Finally, A + D = 34.80 + 52.20 = 87.00. Answer: The total cost of the meal is 87 Pounds<span>. </span>
