P = 2(L + W)
P = 22
L = 2W - 4
22 = 2(2W - 4 + W)
22 = 2(3W - 4)
22 = 6W - 8
22 + 8 = 6W
30 = 6W
30/6 = W
5 = W.....width is 5 cm
L = 2W - 4
L = 2(5) - 4
L = 10 - 4
L = 6....length is 6 cm
Steps To Solve:
-5(3 * -7 + 4y)
~Solve what's in parenthesis
-5(-21 + 4y)
~Distributive Property
105 - 20y
Hope This Helped! Good Luck!
Answer:
1857 miles.
Step-by-step explanation:
We have been given that the scale on a map is 1 cm:30 mi. The distance on the map between San Francisco, CA, and Chicago, IL, is 61.9 cm. We are asked to find the actual distance between San Francisco and Chicago.
We will use proportions to solve our given problem.
Upon substituting map distance between San Francisco and Chicago, we will get:
Therefore, the actual distance between San Francisco and Chicago is 1857 miles.
2) -88, -45, 5, 40
4) -45, -31, 20, 49
6) -74, -63, -45, 38
8) 18, 27, 27, 58
10) -60, -49, -40, 9
12) -45, -18, 80, 82
The bigger negative numbers are the least because negative numbers work the opposite way around of positive numbers. :)
The best way is to do problems over and over again and making mistakes with them.There is no point in doing them if you get correct answers.
When you make mistakes you ask someone what’s wrong and try not to make that mistake again.
That’s how I became a master at maths and physics.
As for help with calculus the important thing is to understand how graphing works.
Once you got that do more questions.
So basically to summarise make mistakes don’t repeat and find out how it works
Hope this helps:)
