Answer:
the cost of a liter of milk is $0.75
the cost of a loaf of bread is $1.75
Step-by-step explanation:
Let
x------> the cost of a liter of milk
y------> the cost of a loaf of bread
we know that
------> equation A
------> equation B
Multiply equation A by
-------> equation C
Multiply equation B by
------> equation D
Adds equation C and equation D
Find the value of x
substitute the value of y in the equation A

Step-by-step explanation:
Answer:
the lease common multiple is 8
PERIMETER = 2 (LENGTH + WIDTH)
PERIMETER = 2 LENGTH + 2 WIDTH
Given: Length 5 inches
P = 2(5 in) + 2w
P = 10 in + 2w
Perimeter is dependent in both length and width. Changes in any length of width will automatically change perimeter.
For find width using the perimeter formula:
P = 10 + 2w
P - 10 = 2w
(P-10)/2 = w
P/2 - 5 = w
w = P/2 - 5
If the perimeter and length is given, you can use the derived formula to solve for width.
