Answer:
x = -2 and y = 2
Step-by-step explanation:
The given equations are :
-5x-2y=6 ...(1)
3x+6y=6 ...(2)
Multiply equation (1) by 3. SO,
-15x-6y=18 ...(3)
Adding equation (2) and (3).
3x+6y-15x-6y = 6+18
-12x = 24
x = -2
Put the value of x in equation (1).
-5(-2)-2y=6
10-2y=6
4=2y
y = 2
So, the value of x is -2 and y is 2.
Answer:
1 3/4
Step-by-step explanation:
For every cup of flour the recipe uses, it uses 3/4 cups of sugar. So, 1 cup of flour plus 3/4 of sugar is 1 3/4.
Answer: W= 5000+0.07S
Step-by-step explanation:
Given: A pharmaceutical salesperson receives a monthly salary of $5000 plus a commission of 7% of sales.
Total wages = Monthly salary + 7% of (Monthly sales)
Let salesperson’s monthly wage be W and monthly sales be S.
Then, W = 5000+(0.07) (S) [Convert percent into decimal by dividing it by 100]
Or W= 5000+0.07S
Required linear equation: W= 5000+0.07S
