nadya68 [22]
If it is 40% off then it is 100-40 = 60% of original price. So we do 180$ * . 6 = $108 before tax. To add on tax we do: 100 + 5 = 105% of that price.

The sum of two numbers is 66. two times the smaller number is 15 more then th larger number what are the numbers
Delicious77 [7]

Let x = big number

Let y = small number

x + y = 66...Equation A

2y = x + 15...Equation B

We have two equations in two unknowns.

x + x + 15 = 66

2x = 66 - 15

2x = 54

x = 54/2

x = 27

Plug x = 27 into EITHER equation above to find y.

I will use Equation A.

x + y = 66

27 + y = 66

y = 66 - 27

y = 39

The two numbers are 27 and 39.

x = (+-) sqrt 100

x = (+-) 10

so the values of x are -10 and 10
