There is a simple rule in multiplication, maybe you don't know it :
<h2>A/B ÷ C/D = A/B × D/C</h2>
So 32 1/4 ÷ 1/8 = 32 1/4 × 8
Answer:
The values of x and y are x = -3 and y = -2
Step-by-step explanation:
In the complex numbers if a + bi = c + di, then the real parts are equal and the imaginary parts are equal
Let us use this rule to solve the question
∵ -21 + 5yi = 7x - 10i
∴ The real parts are -21 and 7x
∴ The imaginary parts are 5y and -10
∵ The real parts are equal
∴ 7x = -21
→ Divide both sides by 7
∴ =
∴ x = -3
∵ The imaginary parts are equal
∴ 5y = -10
→ Divide both sides by 5
∴ =
∴ y = -2
∴ The values of x and y are x = -3 and y = -2
Can you let me know when you get the answer?
The answer is 3.5
To find the average of a set of numbers, add them together then divide the result by how many numbers there were.
To find the average of 4, 4, 4, and 2, add them: 4+4+4+2=14. There were 4 numbers. Divide 14 by 4: the answer is 3.5
