1 nickel = 5 cents
1 dime = 10 cents
13 nickels = 13 *5 = 65 cents
6 dimes = 6*10 = 60 cents.
Total = 65 + 60 = 125 cents.
= 125 cents or $1.25
Answer:
x = 4 and y = - 5
Step-by-step explanation:
note that the product of a complex number and it's conjugate is real
That is
(a + bi)(a - bi) where a, b are real
= a² - abi + abi - b²i²
= a² + b² ← a real number
For (4 + 5i)(x + yi) to be real
we require (x + yi) to be the conjugate of 4 + 5i , that is 4 - 5i
(4 + 5i)(4 - 5i) ⇒ x = 4 and y = - 5
Hello from MrBillDoesMath!
