Solve.
• 4 7 + 2 7 =
Think VARIABLES. Combine like terms.
• 6 7
Remember. When you add or subtract with
radicals, you only combine the coefficients.
Put in standard notation.
• 8.02 x 103
Remember that 103 is 1000. So 8.02 x 1000 =
Move the decimal 3 spaces to the right because
3 is positive and you are going in a positive
direction on the number line.
• 8020.
Put in standard notation.
• 4.67 x 10-2
Remember that 10-2 is .01 So 8.02 x .01 =
Move the decimal 2 spaces to the left because

What is the linear equation?
a. y = - ½ x - 1
b. y = - ½ x + 1
c. y = ½ x - 1
d. y = ½ x + 1
Plug in x & y into each equation. OR determine
the slope and y intercept.
C is the answer.
You want to buy a go-cart. The particular style that you
want comes with a choice of five different colors and
three different wheels.
How many different go-carts can you choose from?
Remember 5 colors combined with 3 wheels.
Use the counting principle or a tree diagram to solve.
YOU DO NOT ADD THE NUMBERS TOGETHER.
• 5 x 3 = 15 possible go-carts.
• A person can order one entrée, one side dish, and
one dessert from the menu.
• Draw a tree diagram for a menu with 3 entrées , 4
side dishes, and 2 desserts.
• Draw 3 lines. From each line comes 4 lines. From
