Write a positive or negative integer that represents the following:

A football team loses 14 yards on a play.

loses indicated a negative

-14

Evaluate:

4 3

------- + -------

20 12

4 (3) 3 (5)

------- + -------

20 (3) 12 (5)

12 15 27

------- + ------- = -------

60 60 60

27 ÷ 3 9

------- = --------

60 ÷ 3 20

Write the Prime Factorization of 24.

24

/ \

2 × 12

/ \

2 × 6

/ \

2 × 3

Prime factorization = 2 × 2 × 2 × 3 or 2³ × 3

----------------------------------------------------------------------------------------------------------

Tell whether the ordered pair is a solution of the equation:

y = x + 7; (1, 6)

(x, y)

6 = 1 + 7

6 = 8

Not a solution

----------------------------------------------------------------------------------------------------------

Simplify and Graph the following:

x = -2 - 3

x = -5

<-----|--------------------------------->

-5

Don't worry about the other numbers. Put a dot on -5 and draw a line vertically (up and down).

----------------------------------------------------------------------------------------------------------

If the weight of a package is multiplied by (5/7). The result is 40.5 pounds. find the weight of the package.

x(5/7) = 40.5

--------- --------

÷(5/7) ÷(5/7)

x = 56.7

----------------------------------------------------------------------------------------------------------

A = (1/2)bh

A= (1/2)(8)(5)

A = (1/2)(40)

A = (20)

A = 20in²

----------------------------------------------------------------------------------------------------------

I hope this helps!
