Assignment 1, Sep 23 2008- To simplify means to find the smallest possible value. To solve means to find the answer to an equation. To evaluate means to subsitute for the variable.

EX-Simplify- 50/100=1/2 Solve- 23+78= 101 Evaluate- x=3, 2x-4=2*3-4=2

Assignment 2, Oct 6, 2008- To simplify the expression -2x+12-3x+4-3y, You would first look over the variable expression and then you would find the like terms: -2x, -3x, 12, 4, then you would combine the like terms: -2x-3x= -5x 12+4=16, the you would put the numbers in the right order with the correct sign: -5x+16-3y and that is as far as you can simplify.

To evaluate the expression -2x+3y, x=-2 y=-4, you would first substitute the given values for the variables x and y which would make the expression -2*-2+3*-4, then you would solve the expression using the order of operations which would be: -2 times -2 and that equals -4, then you would multiply 3 times -4 which equals -12 and then you would add -4+-12 which equals -16.

Assignment 3- February 10- Two equation questions 1. Jake rented a scooter which had a initial cost of $29.97 plus $.92 added on per day. If he traveled for 4 days what would the cost of the rental be? 2. Carter bought 3.4 feet of thread which costed him $109.89. If it took him 47 sec to cut .2 feet of thread how long would it take to cut 3.4 ft of thread?
