Simplify 4.2(2x-0.5y)-2(4.1x-0.3y)

x = 7.5y

Step-by-step explanation:

Simplifying

4.2(2x + -0.5y) + -2(4.1x + -0.3y) = 0

(2x * 4.2 + -0.5y * 4.2) + -2(4.1x + -0.3y) = 0

(8.4x + -2.1y) + -2(4.1x + -0.3y) = 0

8.4x + -2.1y + (4.1x * -2 + -0.3y * -2) = 0

8.4x + -2.1y + (-8.2x + 0.6y) = 0

Reorder the terms:

8.4x + -8.2x + -2.1y + 0.6y = 0

Combine like terms: 8.4x + -8.2x = 0.2x

0.2x + -2.1y + 0.6y = 0

Combine like terms: -2.1y + 0.6y = -1.5y

0.2x + -1.5y = 0

Solving

0.2x + -1.5y = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1.5y' to each side of the equation.

0.2x + -1.5y + 1.5y = 0 + 1.5y

Combine like terms: -1.5y + 1.5y = 0.0

0.2x + 0.0 = 0 + 1.5y

0.2x = 0 + 1.5y

Remove the zero:

0.2x = 1.5y

Divide each side by '0.2'.

x = 7.5y

Simplifying

x = 7.5y

answer: ur mum is gay

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
