Step-by-step explanation:
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
Answer:
x=-1/4
Step-by-step explanation:
2/5+3/5x=x+5/10
subtract 2/5 form both sides
3/5x=x+1/10
subtract x form both sides
-2/5x=1/10
Multiply both sides by 5
-2x=1/2
x= - 1/4
Started with: $60
left with: $10
items bought: 20
60 - 10 = 50 < amount spent
50/20 = amount spent/items bought
= $ 2.50 < each chocolate
you can check this by multiplying the items bought and the amount each item cost to get how much you spent
20 × 2.5 = 50
Stephanie started off with 60 dollars and ended with 10 dollars
60 - 50 = 10
hope this helps :)
