Hello from MrBillDoesMath!
Answer:
L = 35, W = 25
Discussion:
The attachment shows that
P = 2L + 2W = 120
and
L = 10 + W
2L + 2W = 120 => Substitute the last equation into the first one
2(10 + W) + 2W = 120 =>
20 + 2W + 2W = 120 => combine like terms
20 + 4W = 120 => subtract 20 from both sides
4W = 120 -20 = 100 => divide both sides by 4
W = 100/4 = 25
Hence, L = 10 + W = 10 + 25 = 35
Thank you,
MrB

Answer:
the answer is d.
Step-by-step explanation:
D} the independent variable is cows, and the dependent variable is milk.
The independent variable is cows, and the dependent variable is milk.
The value of the independent variable, often denoted by x, does not depend on the value of another variable. The value of the dependent variable, often denoted by y, depends on the value of the independent variable.
