Number Cruncher!

## Algebra I – Chapter 1

1.4 – Translating words into symbols

1.5 – Translating sentences into Equations

### You Try!

• Four times a number

• Four less than five times a number

• Ten times the sum of a number and nine

• Eleven more than one third of a number

### You Try!

• Four times a number 4N

• Four less than five times a number 5N -4

• Ten times the sum of a number and nine

10(N + 9)

• Eleven more than one third of a number

⅓N + 11

### Formulas:

• Formulas are equations that state rules about relationships.

• Area of a Rectangle:

• Perimeter of a Rectangle:

• Distance Traveled:

• Cost:

### Equations:

• When you add the word is, then it becomes an equation. Now it can be solved.

• Ex: Three times a number decreased

by 8 is 10

2x

3

x

x

P = 30m

A = 24m

4

P = 10m

### Reflection:

• What is a symbol? Give a couple of examples.

• What is a formula?

• When does an expression become an equation?
