First, before multiplying to cancel the fraction, let's isolate x by subtracting both sides by 3:
b/9 < 1
To cancel out the fraction, we multiply both sides by 9:
x < 9
Their original price was 3.50, meaning that 3.50 is 100% of the price. We can find the percentage of the new price, 2.80, by using ratios.
3.50 100%
2.80 x%
x = 100% * 2.80 / 3.50 = 80%
The new price, 2.80, is 80% of the original price. Since 100% - 80% is 20%, this means that the decrease of the price was 20%.
Answer:
The length of BC = 12
Step-by-step explanation:
c^2 = a^2 + b^2
15^2 = 9^2 + b^2
225 = 81 + b^2
b^2 = 225 - 81
b^2 = 144
b = 12
The length of BC is 12
