term in parentheses or combine like terms in parentheses? Why?"

Answer:

The first thing you ever do when simplifying an expression is distributing the coefficient. For example the expression 3(5x+6+4x) The first thing we would do is distribute the 3 into each value in the parantheses. It would make sense to add the 4x and 5x, but that goes out of order. This is just the rules when it comes to follwing distributive property in it's simplest form.

Half of a number increased by 4 is 30.
Hitman42 [59]

Answer:

\frac{1}{2}x+4=30

52

Step-by-step explanation:

First, write the equation out in the algebraic form. Half of a number is equivalent to a number times 1/2. Additionally, increasing a number by 4 is just adding 4. So the equation is \frac{1}{2}x+4=30.

Then, use algebra to solve.

1) Subtract 4 from both sides

1/2x=26

2) Multiply both sides by 2, because that is the same as dividing by a fraction

x=52
