Mathematics

Rudik [331]3 years ago

Step 1: Add the two equations.

Step 2: Solve for x.

Step 3: To find the y-value, substitute in 3 for x in one of the equations.

Step 4: Solve for y.

Step 5: Identify the solution as an ordered pair.

What if adding or subtracting does not eliminate a variable? Example. 3x – y = 8. x + 2y = 5.

Absolute Mad Deviation is used to see how spread out data is, you find the mean of data then subtract the mean from each number (absolute value) and then find the mean with the subtracted numbers.
Brand A MAD: 2.6925

It’s Brand A :)

Answer:

Step-by-step explanation:

Let Kaylee used the amount of green paint in the mixture = x ounces

and the amount of white paint = y ounces

Total amount of mixture = 50 ounces

Equation will be x + y = 50 ------(1)

Ratio of green paint to the white paint in the mixture = 5 : 3

⇒  x : y = 5 : 3

⇒ \frac{x}{y}=\frac{5}{3}

⇒ x = \frac{5}{3}y ---------(2)

Therefore, By solving these two equations by substitution method we can get the amount of green and white paint used in the mixture.

Undefined (not a real number)

The square root of -256 would result in an imaginary number so by terms, it's "not real". The imaginary number would be 16i. 16x 16 =256, but since it's negative, it's √16 √16i.
