15. 5 - -10 = 5 + 10 = 15 → 15 + -10 = 15 - 10 = 5
10% off 15 = 15 - (10% x 15) = 13.5
6. (10 x 15) ÷ (10 + 15) = 150 ÷ 25 = 6
15% of 10 pounds is 1.5 pounds.
10% times 15%= 10% * 15%= 0.10 * 15%= 1.5% or 0.015

10% off 15 = 15 - (10% x 15) = 13.5
10/15 = 10 ÷ 15 = 0.666... ≈ 0.67
-15-(-10)= -15+10= -5
Points: (6, -10) and (-15, 15) Slope: (-10-15)/(6--15) = -25/21
10 to the power of -15 is 1/10^15. (1/1,000,000,000,000,000 [15 zeroes])It can also be written as 0.000000000000001 (There are 15 zeroes).OR -1,000,000,000,000,000 (15 zeroes).
6. (10 x 15) ÷ (10 + 15) = 150 ÷ 25 = 6
