2) Solve for x: 6x + 10 = 40 x = ____

Subtract 10 from both sides (6x + 10 - 10 = 40 - 10) This means that 6x = 30 Divide both sides by 6 (6x/6 = 30/6) This means x = 5

Explanation

Subtract 10 from both sides (6x + 10 - 10 = 40 - 10) This means that 6x = 30 Divide both sides by 6 (6x/6 = 30/6) This means x = 5

3) What is the perimeter of an eqilateral trianlge with a base of 5cm? P = ___ cm

Since this is an equilateral triangle, all sides measure 5cm.
Perimeter = side+side+side
5+5+5=15

Explanation

Since this is an equilateral triangle, all sides measure 5cm.
Perimeter = side+side+side
5+5+5=15

4) What is the area of a triangle with a base of 10cm and a height of 7cm? A = ___ cm

Area = base x height, but something must be cut in half (divided by 2).
The simplest thing to do here is to cut the base (10) in half, so:
5 x 7 = 35

Explanation

Area = base x height, but something must be cut in half (divided by 2).
The simplest thing to do here is to cut the base (10) in half, so:

5) How many cups are in 16 gallons?

144

256

One gallon = 16 cups, so 16 gallons = 16 x 16 cups, or 256 cups.

Explanation

One gallon = 16 cups, so 16 gallons = 16 x 16 cups, or 256 cups.

6) One of the following statements about triangles is false. Place a check beside the false statement.

All triangles have 3 sides and 3 angles.

All triangles have at least two equal sides.

The angles of all triangles add up to 180 degrees.

The hypotenuse of a right triangle is always the longest side.

Some triangles have no equal sides. These are called "scalene" triangles. All of the other statements are true.

7) Angela's test scores in math class are 100, 95, 100, 93, and 70. What is her average in math class?

To find her average, add the test scores and divide by five (because there were five scores). This comes to 91.6, which rounds up to 92.

8) Charlie buys a new television at a cost of $536. If the tax is 8%, how much will he have to pay in all?

$42.88

$493.12

$587.99

$107.20

$578.88

Multiply the cost of the television by the tax (written as a decimal): 536 x .08 = 42.88 Add 42.88 back to the price of the television: 536 + 42.88 = 578.88

Explanation

Multiply the cost of the television by the tax (written as a decimal): 536 x .08 = 42.88 Add 42.88 back to the price of the television: 536 + 42.88 = 578.88

9) In a right triangle, if side a = 12cm and side b = 14cm, what is the measure of side c?

15.3cm

18.4cm

14.8cm

13cm

a squared + b squared = c squared, so...
12 squared (144) + 14 squared (196) = c squared
144 + 196 = c squared
340 = c squared, so the square root of 340 = c
c = 18.4

Explanation

a squared + b squared = c squared, so...
12 squared (144) + 14 squared (196) = c squared
144 + 196 = c squared
340 = c squared, so the square root of 340 = c
c = 18.4
