Answer:
x = 48 and y = 104
Step-by-step explanation:
Given equations are:
From equation 1:
Putting the value of y in equation 2
Now we have to put the value of y in one of the equation to find the value of x
Putting y = 104 in the first equation
Hence,
The solution of the system of equations is x = 48 and y = 104

Step-by-step explanation: SORRY IF I GET IT WRONG
Answer:
The correct answer is C, as growth on stock E is bigger from the growth of stock B
Step-by-step explanation:
In order to resolve this problem, we must have in mind that the negative numbers are smaller when they are more distant from 0, and that positive numbers are bigger when they are more distant from 0. So, the biggest number of growth is the one that is more distant from 0.
The correct answer is C, as growth on stock E is bigger from the growth of stock B.
Answer: x = 38.4
Step-by-step explanation:
7-x/3 = -1-x/8
1. Add 1 to both sides
8-x/3 = -x/8
2. Add x/3 to both sides
8 = x/3 - x/8
3. Multiply x/3 by 8/8 and x/8 by 3/3 to get the same number under the quotient
8 = 8x/24 - 3x/24
4. calculate the difference between 8x/24 - 3x/24
8 = 5x/24
5. Multiply both sides by 24/5, and there is the answer
38.4 = x
