The owner of a discount clothing store ordered six belts and eight hats for $140. A

Akimi4 [234]

Let b = the price of the belt
h = the price of the hat
Equation 1
6b + 8h = 140
Equation 2
9b + 6h = 132
Multiply equation 1 by 1.5
1.5(6b + 8h = 140)
9b +12h = 210
Subtract by equation 2
9b-9b +12h-6h = 210-132
6h = 78
h = 13
Substitute h = 13 in equation 1
6b + 8*13 = 140
6b = 140 - 104
6b = 36
b = 6
The price of the hat is $13.00 each
The price of the belt is $6.00 each

What will be the values of x and y as a result of the following code? int x = 25, y = 8; x = y; x = 25, y = 8 x = 34, y = 8 x =

mrs_skeptik [129]

The values of x and y as a result of the code are 8 and 8

<h3>How to determine the values of x and y as a result of the code? </h3>

The code is given as:

int x = 25, y = 8;

x = y;

At the first line, we have

x= 25 and y = 8

On the second line, where we have

x = y

This means that

x = 8 and y = 8

Hence, the values of x and y as a result of the code are 8 and 8
