Algebra 1 Chapter 1 Review

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is given by the formula: P = 2(length + width).

Front

If the length of a rectangle is 3 more than its width, how can we express this relationship algebraically?

Back

If the width is 'w', then the length can be expressed as 'w + 3'.

Front

Translate 'Seven more than five' into mathematical symbols.

Back

5 + 7

Front

Translate 'Seven is more than five' into mathematical symbols.

Back

7 > 5

Front

What is the algebraic expression for Bob's age if Tom is 't' years old and Bob is twice Tom's age?

Back

Bob's age is 2t.

Front

How do you calculate the change received from a $5 bill after buying two boxes of raisins at 'r' cents each and a bag of pretzels that costs 50 cents more than a box of raisins?

Back

Change = 500 - (2r + (r + 50)) = 500 - (3r + 50).

Front

What is the first step to solve the equation 2(w + 3) = 26?

Back

Distribute the 2: 2w + 6 = 26.

Front

What does it mean to 'translate' a word problem into an algebraic expression?

Back

It means to convert the words into mathematical symbols and expressions that represent the relationships described.

Front

What is the value of 'w' if the perimeter of a rectangle is 26 and the length is 3 more than the width?

Back

Set up the equation: 2(w + (w + 3)) = 26, then solve for 'w'.

Front

If Tom is 't' years old now, what will his age be in four years?

Back

Tom's age in four years will be t + 4.
