Answer:
Step-by-step explanation:
P = 480
P = 2 length + 2 width
but we also know that
2width = length
so plug that into the length
P = 2(2width) + 2 width
480 = 4 width + 2 width
480 = 6 width
80 = width
160= length
see?
Step-by-step explanation:
The key to solving word problems is in translation: turning word into math
Below is a general approach to most/any word problem
1. Read through the whole question once, without lingering over details, to get some sense of the overall problem
2. identify and label the variables or unknowns in a way that makes it easy to remember what they stand for.
3. translate the problem into one or more equations, sentence by sentence, and be careful of the order in which you translate the terms
4. solve the equation(s)
5. check your work
It is -3 to start off with, on Monday. On Tuesday morning it would be -3 - 2 degrees, = -5 degrees. By Tuesday evening it was 4 degrees lower than in the morning, so -5 - 4 degrees = -9 degrees on Tuesday evening.
Hope this helps xox :)
