Answer:
(1 , 3)
Step-by-step explanation:
y = -x + 4
y = 3x
=> -x + 4 = 3x
=> 4x = 4
=> x = 1
y = 3(1) = 3
Solution is (1 , 3)
The perimeter is the total of the length • 2, + Width • 2. Doing it in reverse order, 230 - 2(Width) = 104.

Answer:
The regular size is more economical.
Step-by-step explanation:
Consider the provided information.
A regular tube of toothpaste costs $2.50 for 3.2 ounces.
Find out the unit rate as shown below:
![\frac{\$2.50}{3.2}=\$0.78](https://tex.z-dn.net/?f=%5Cfrac%7B%5C%242.50%7D%7B3.2%7D%3D%5C%240.78)
Therefore, the cost of one ounce is $0.78.
A travel size tube costs $1.00 for 1.2 ounces.
Find out the unit rate as shown below:
![\frac{\$1}{1.2}=\$0.833](https://tex.z-dn.net/?f=%5Cfrac%7B%5C%241%7D%7B1.2%7D%3D%5C%240.833)
Therefore, the cost of one ounce is $0.833.
From the above calculation we can observe that regular tube toothpaste price is better buy.
Now find the percent as shown:
Firs find the difference
$0.83-$0.78 = $0.05
Therefore,
![\frac{0.05}{0.78}\times 100\approx 6.41](https://tex.z-dn.net/?f=%5Cfrac%7B0.05%7D%7B0.78%7D%5Ctimes%20100%5Capprox%206.41)
Hence, regular tube is 6.41% less costly as compare to travel size.
