Which number can each term of the equation be multiplied by to eliminate the decimals before solving?
5.6j – 0.12 = 4 + 1.1j

100 is the number which can be multiplied to eliminate the decimals

Step-by-step explanation:

Given:

Which number can each term of the equation be multiplied by to eliminate the decimals before solving

5.6j – 0.12 = 4 + 1.1j

Solution:

Notice that the constants and the coefficients in this equation contains decimal. All the numbers are in decimal up to tenth place except 0.12 which has decimal up to hundredth place.

Therefore, if we want to eliminate the decimal from 0.12 we have to multiply it by 100.

Thus the given equation will be multiplied by 100 to eliminate decimal from the terms.

100(5.6j – 0.12 = 4 + 1.1j)

By multiplying the equation by 100 we get:

560j - 12 = 400 + 110j

Thus 100 is the number which can be multiplied to eliminate the decimals

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
