If a taxi costs $7 plus $0.85 per mile, how do you calculate the total cost for a ride of 11 miles?

Back

Total cost = 7 + (0.85 * 11) = $16.35.

Front

Calculate the value of 3a + 5b if a = 4 and b = 6.

Back

3(4) + 5(6) = 12 + 30 = 42.

Front

How do you set up an equation to find the cost of each candy bar if Tom spent $18.00 on a soft drink and 7 candy bars?

Back

To reduce it to its simplest form by combining like terms and eliminating parentheses.

Front

What is the distributive property in algebra?

Back

a(b + c) = ab + ac; it allows you to multiply a single term by two or more terms inside parentheses.

Front

How do you solve for x in the equation 4x + 7 = 18?

Back

Subtract 7 from both sides: 4x = 11; then divide by 4: x = 11/4.
