What is the formula to find the time it takes for one object to catch up to another when both are moving in the same direction?

Back

Time = (Distance of the first object) / (Speed of the second object - Speed of the first object)

If Davis leaves Starbucks traveling East at 50 mph and Jackson leaves 2 hours later at 60 mph, how do you calculate when Jackson will pass Davis?

Back

Calculate the distance Davis travels in 2 hours (100 miles), then use the relative speed (10 mph) to find the time it takes Jackson to cover that distance (10 hours).

What is the Distributive Property in mathematics?

Back

The Distributive Property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

What does the Identity Property of Addition state?

Back

The Identity Property of Addition states that adding zero to any number does not change the value of that number (e.g., a + 0 = a).

Front

Write the expression for '4 less than the product of x and 2'.

What is the Commutative Property of Addition?

Back

The Commutative Property of Addition states that changing the order of the addends does not change the sum (e.g., a + b = b + a).

Front

What is the Associative Property of Multiplication?

Back

The Associative Property of Multiplication states that the way in which numbers are grouped in multiplication does not change the product (e.g., (ab)c = a(bc)).

Front

How do you express 'the sum of a number x and 5' as an algebraic expression?

Back

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal (e.g., x + 2 = 5), while an inequality shows that one expression is greater than or less than another (e.g., x + 2 < 5).
