$1.36
Step-by-step explanation:
First, add together the prices of all the clothes:
18.28 + 42.39 + 12.97
= 73.64
Then, subtract this from 75:
75 - 73.64
= 1.36
So, he will have $1.36 left after buying the clothes
Answer:
x = -3, y = 1
Step-by-step explanation:
To find the value of x and y, find the determinant of original matrix, which would be 21.
Then, substitute the value of x with the solutions to the equations and find the determinant of that matrix, which is -63.
Cramer's rule says that Dx ÷ D is the value of x. So, -63 ÷ 21 = -3.
So, the x-value is -3.
You can find the determinant of the y-value in the same way, and you'll find out that y = 1.
Hope this helped! :)
