Answer:
sure I just take a guess is the correct answer d all of the above?????
Step-by-step explanation:
Answer:
(D) Divide the first equation,
, by 2.
Step-by-step explanation:
Given:
![2x + 4y = 8 \ \ \ \ equation \ 2](https://tex.z-dn.net/?f=2x%20%2B%204y%20%3D%208%20%5C%20%5C%20%5C%20%5C%20equation%20%5C%202)
We need to find the operation performed on equation so as to get resultant equation as:
![-2x + 4y = 8](https://tex.z-dn.net/?f=-2x%20%2B%204y%20%3D%208)
![2x + 4y = 8](https://tex.z-dn.net/?f=2x%20%2B%204y%20%3D%208)
From Above we can see that there is no change in equation 2 with respect to resultant equation.
Also Resultant equation is simplified form of equation 1.
Simplifying equation 1 we get;
![-4x + 8y = 16](https://tex.z-dn.net/?f=-4x%20%2B%208y%20%3D%2016)
We can see that 2 is the common multiple on both side.
Hence we will divide equation 1 with 2 we get
![\frac{-4x}{2}+\frac{8y}{2}=\frac{16}{2}\\\\-2x+4y=8](https://tex.z-dn.net/?f=%5Cfrac%7B-4x%7D%7B2%7D%2B%5Cfrac%7B8y%7D%7B2%7D%3D%5Cfrac%7B16%7D%7B2%7D%5C%5C%5C%5C-2x%2B4y%3D8)
which is the resultant equation.
Hence (D) Divide the first equation,
, by 2 is the correct option.
If x represents the number of flower baskets, then, just as you showed, the answer cant be either a or b because store A doesnt charge $15 per flower basket but rather $15 for delivery. To see whether it is c or d, simply use the same number to represent the number of flower baskets in both inequalities. The easiest would be 1 because then youre multiplying - in the case of store A - 19.25 (how much each flower basket costs) times 1 (the total number of flower baskets) and then adding 15 (the cost of delivery) which is a total of 34.25. For store B it would be 17.5 times 1 plus 30 which equals 47.5. Therefore, the inequality for store A is less than that of store B, so D would be the answer.
