Step-by-step explanation:
Write an equation system based on the problem
For an instance, e stands for the price of a carton of eggs, and b stands for the price of a loaf of bread
"Kate bought 3 cartons of eggs and 5 loaves of bread for $30.07" could be written as 3e + 5b = 30.07 (first equation)
"Melissa bought 2 cartons of eggs and 2 loaves of bread for $14.74" could be written as 2e + 2b = 14.74 (second equation)
Solve the equation system using elimination method
Eliminate b to find e. To eliminate b, we should equalize the coefficient of b.
3e + 5b = 30.07 (multiplied by 2)
2e + 2b = 14.74 (multiplied by 5)
-------------------------------------------
6e + 10b = 60.14
10e + 10b = 73.70
------------------------- - (substract)
-4e = -13.56
e = -13.56/-4
e = 3.39
The price for a carton of eggs is $3.39

Answer:
![n * \frac{1}{2} = 95](https://tex.z-dn.net/?f=%20n%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%3D%2095%20)
Step-by-step explanation:
Required:
Select the equation that most accurately depicts the word problem
One-half of a certain number is 95.
Take the certain number to be n.
This statement in equation form will be:![n * \frac{1}{2} = 95](https://tex.z-dn.net/?f=%20n%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%3D%2095%20)
Therefore, the equation that most accurately depicts the word problem is ![n * \frac{1}{2} = 95](https://tex.z-dn.net/?f=%20n%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%3D%2095%20)
Although your options are incomplete, but this answer is correct.
The * symbol can be replaced with a dot sign
