Warm-up October 24, 2016 Complete Monday’s Weekly Basics problems On the back of the WB answer this question: Explain the differences and similarities between an algebraic expression and an algebraic equation.

Ratios and Proportional Relationships Rate– A ratio comparing two different units. Unit rate– A rate with a denominator of 1. Ratio- A comparison of two quantities. Equivalent ratios - Fractions that are equal in value, but many have different numerators and denominators. Proportion- A statement that two ratios are equal. Direct Proportion: The relation between two quantities whose ratio remains constant. The graph is a straight line that passes through the origin.

Marla likes to babysit for her parents’ friends Marla likes to babysit for her parents’ friends. She charges a $5 fee for travel expenses and an additional $12.50 per hour for every hour she babysits. Write an expression that represents how much Marla charges. How much will Marla make if she babysits for 3 hours?

Brandon gets $20 a month for allowance, plus $2 for each chore he does around the house. Let c represent the number of chores he completed. Write an expression representing how much Brandon can earn in a month. How much will Brandon earn if he does 13 chores in a months’ time?

Clyde had $50 to spend on clothes at Old Navy Clyde had $50 to spend on clothes at Old Navy. After buying t-shirts, he had $18.20 left. How much did each t-shirt cost?

Use your addition rules! 47 + 18 = -47 + 18 = 47 + -18 = -47 + -18 =

Use your addition rules! 28 + 37 = -28 + 37 = 28 + -37 = -28 + -37 =

Use your addition rules! 7 + 35 = -7 + 35 = 7 + -35 = -7 + -35 =

Use your addition rules! 94 + 156 = -94 + 156 = 94 + -156 = -94 + -156 =

Use your addition rules! 235 + 28 = -235 + 28 = 235 + -28 = -235 + -28 =
