Answer:

14. 1 inch = 96 miles (12 × 8)

1/2 inch = 48 miles (96 ÷ 2)

96 + 48 = 144 miles

3 3/4 = 3.75

144 ÷ 3.75 = 38.4

A. 38.4 mph

15. Adding a negative number is the same as just subtracting.

D. 35(2) - 1/2(15)

20. - = withdrew because you are subtracting

+ = deposited because you are adding

D. Peter withdrew $47.27 and deposited $598, increasing his bank account by $550.73

21. Yana: 7 - 3 + 6 - 1 + 8 - 2 = 15

15 ÷ 6 = 2.5 average

Amber: 1 + 5 - 2 + 4 - 2 + 6 = 12

12 ÷ 6 = 2 average

2.5 - 2 = 0.5

A. Yana's average number of points is 0.5 point greater than Amber's

3(2 – 0.9h)  (1.3h  4)
SCORPION-xisa [38]

If you are solving for "h" here you go.

Simplifying

3(2 + -0.9h) + (-1.3h + -4) = 0

(2 * 3 + -0.9h * 3) + (-1.3h + -4) = 0

(6 + -2.7h) + (-1.3h + -4) = 0

Reorder the terms:

6 + -2.7h + (-4 + -1.3h) = 0

Remove parenthesis around (-4 + -1.3h)

6 + -2.7h + -4 + -1.3h = 0

Reorder the terms:

6 + -4 + -2.7h + -1.3h = 0

Combine like terms: 6 + -4 = 2

2 + -2.7h + -1.3h = 0

Combine like terms: -2.7h + -1.3h = -4h

2 + -4h = 0

Solving

2 + -4h = 0

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + -4h = 0 + -2

Combine like terms: 2 + -2 = 0

0 + -4h = 0 + -2

-4h = 0 + -2

Combine like terms: 0 + -2 = -2

-4h = -2

Divide each side by '-4'.

h = 0.5

Simplifying

h = 0.5
