Let x = the smaller numberLet 3x + 15 = the larger numberx + 3x + 15 = 634x = 48x = 123(12) + 15 = 51
First, find the percentage of the price after the sale occures
percent = 100% - 20%
percent = 80%
We need to find the price for the pairs with the percentage above
new price = percentage of new price/percentage of old price × old price
new price = 80%/100% × 55
new price = 4/5 × 55
new price = 44
The new price is $44
Now we estimate how much the tax
tax = 6% × 44
tax = 6/100 × 44
tax = 2.64
Calculate how much Josie will pay
pay = new price + tax
pay = 44 + 2.64
pay = 46.64
Josie will pay $46.64
Putting the same common denominator would be 30. & the numerator for 1/6 would be 5, while the numerator for 3/5 would be 18. & if you subtract 5-18 you can't really do that so just switch it up (18-5) & you'd get -13 & the common denominator is 30, so in that case -13/30
They are the same. deci means 10 (think decade is 10 years) so decimeter is cm/10 so 30/10=3decimeters
