Across
- 3. Two ratios are equivalent if they have the same value when simplified.
- 4. A ratio compares two quantities by division. A ratio may be written using a colon, but is more often written as a fraction.
- 6. To make something smaller (a fraction: To put a fraction into a simplest form.)
- 8. expression An expression is a combination of individual terms separated by plus or minus signs. Numerical expressions combine numbers and operation symbols; algebraic.
- 10. For polygon a vertex is the point at which two line segments meet to form a “corner”.
- 11. Replacing one symbol with a number, variable, or another algebraic expression of the same value. Substitution does not change the value of the overall expression.
- 12. Two expressions are equivalent if they have the same value. For example, 2+3 is equivalent to 1+4.
Down
- 1. have the same shape but are not necessarily the same size.
- 2. To make something larger.
- 5. fractions Two fractions are equivalent if they have the same numerical value. For example, 3/6 and 5/10 are equivalent fractions.
- 7. An expression is a combination of individual terms separated by plus or minus signs.
- 9. To find the numerical value of. To evaluate an expression, substitute the value(s) given for the variable(s) and perform the operations according to the Order of Operations.
- 10. A symbol used to represent one or more numbers. In this course, letters of the English alphabet are used as variables.
