X over 49.5 and 20 over 100 then you cross multiply and you get 100x is equal to 990 you divide 100x and 990 both by 100 and get x and 9.9 then you have 50 seniors a month that you give the discount to so you multiply 9.9 by 50 and get 495 so the total discount you give on an average monthly basis is $495.00 Hope this helped
Answer:
Step-by-step explanation:
The way to do this is just to add the two real parts together and add the two imaginary parts together.
2 + 5j + 7 - 3j
2 + 7 + 5j - 3j
9 + 2j
Here you have two unknowns, so you would need two equations (system of equations). By using w to represent walnuts and c to represent chocolate chips your equations would be 5w + 2c = 10 and 3w + 8c = 23, the coefficients being the amount of pounds of walnuts and chocolate chips and the right hand side of the equations being the total price. From there you can either solve for one variable in terms of the other and plug in to the other equation, or you could subtract one equation from the other ( I personally prefer solving for one variable in terms of the other and then plugging in to the other equation).
The equation to find the number of assignments in the math section of Savannah's binder is 197 = x + 132
<h3>Equation</h3>
- Assignment in the history, science, and art sections combined = 132 assignment
- Assignment in the math section = x
- Total assignment = 197 assignments
Total assignment = Assignment in math + Assignment in other subjects
197 = x + 132
197 - 132 = x
65 = x
Therefore, the equation to find the number of assignments in the math section of Savannah's binder is 197 = x + 132
