Find the sum.<br>(w - 2.4) + (1 - 0.5w)​
vodka [1.7K]

The sum of the given expression { (w - 2.4) + (1 - 0.5w)​ } is 0.5w - 1.4.

<h3>What is the sum of the given expression?</h3>

Given the expression in the question;

(w - 2.4) + (1 - 0.5w)​

Remove the parenthesis

w - 2.4 + 1 - 0.5w

Collect like terms and simplify

w - 2.4 + 1 - 0.5w

w  - 0.5w - 2.4 + 1

1w  - 0.5w - 2.4 + 1

0.5w - 1.4

Therefore, the sum of the given expression { (w - 2.4) + (1 - 0.5w)​ } is 0.5w - 1.4.

How to solve a variable?​
amm1812

Answer:

If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

Hope this helps :D
