3 ( x ) + 55 = 85
Answer To Solving Y:
Let's solve your equation step-by-step.
3x + 55 = 85
Step 1: Subtract 55 from both sides.
3x + 55 − 55 = 85 − 55
3x = 30
Step 2: Divide both sides by 3.
3x / 3 = 30 / 3
x = 10

2 ( y ) - 5 = 95
Answer:
Let's solve your equation step-by-step.
2y − 5 = 95
Step 1: Add 5 to both sides.
2y − 5 + 5 = 95 + 5
2y = 100
Step 2: Divide both sides by 2.
2y / 2 = 100 / 2
y = 50

But, the anwer should be 180 degrees
Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To solve this, we will be doing a semi-alternate route, but it will get us to our answer...
400 / 100 = 4
30 / 4 = 7.5 seconds
60 * 60 * 7.5 = 27,000 meters per hour
<em></em><em>Lets plug it into our meters to miles formula...</em>
27,000 / 1,609.344 ~ 16.777 miles per hour
So...
The answer is: The Polar Express was going 27,000 meters per hour (or roughly close to 16.777 miles per hour)...
The goal is to get the volume as large as possible while the surface area is made as small as possible. Why? Because the volume is the amount of stuff you can hold and the surface area is the amount of material to make the container.
Consider an example of making a cup. The inside portion is the amount the cup can hold. The more liquid, the better. The cup makers want to use as little material as possible so that they reduce costs. If the cup makers produce a cup that has volume of 10 cubic inches and uses 10 square inches of material, then the surface area to volume ratio is 10:10 which reduces to 1:1. A more efficient cup is made if that same volume (10 cubic inches) can be made for less material say 5 square inches to make the ratio now 5:10 which reduces to 1:2.
So in summary, reducing the surface area to volume ratio will make more sense economically as the company makes more money while reducing costs (therefore increasing overall profit)
