Answer:

28 weeks

Step-by-step explanation:

She starts with $500.

She adds $40 per week. In w weeks, she adds 40w.

After w weeks, she has 500 + 40w.

The total must equal $1620.

500 + 4w = 1620

Subtract 500 from both sides.

4w = 1120

Divide both sides by 40.

w = 1120/40 = 28

Answer: 28 weeks

Answer: a) -27, b) 35, c) 14

Step-by-step explanation:

a) When a positive number is multiplied by a negative number, your answer is negative, and since we know that 9 × 3 = 27, and that this figure has to be negative (since 9 is negative), the answer is -27.

b) Multiplying two negative numbers gives a positive number, and since 7 × 5 = 35, the answer is positive 35 (as both 7 and 5 in the original question are negative).

c) Follows just like b.
