Answer 1

See below.

Explanation:

1.

(10 * 20)/(20 + 30) = 200/50 = 4

2. a.

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

2. b.

10

3.

{-1, -3, -5, -7, ... }

4.

407,006,962

5.

1, 2, 3, 4, 5, 6, 10

6.

7.

2, 3, 4, 6, 8, 9

8.

-4 -3 -2 -1 0 1 2 3 4

<-------+------+<-----+------+------+------+------O------+------+------>

Start at the 2, shown by the open circle. Draw a segment to the left 5 units long to subtract 5. You end up at -3.

9.

6400 =

= 6000 + 400 + 0 + 0

= 6 * 1000 + 4 * 100 + 0 * 10 + 0 * 1

10.

x + $4.60 = $10.00

x + $4.60 - $4.60 = $10.00 - $4.60

x = $5.40

11.

p - 3850 = 4500

p - 3850 + 3850 = 4500 + 3850

p = 8350

12.

8z = $50.00

8z/8 = $50.00/8

z = $6.25

13.

I don't see an equation.
