This question is not even trying to test your arithmetic. It's just testing
to see whether you know how to read numbers in words properly.
When you read numbers in words, the only time you ever say "and"
is for a decimal point. There are no decimals in this question, so the
"and" is not a part of any numbers.
The question gives you two numbers. The word "and" is the marker
that's
BETWEEN them. The two numbers are 1,300 and 950 .
The first thing the question wants you to do is write the numerical
expression for all the words. That's (1300 - 950) / 4 .
The next thing you're supposed to do is"evaluate the expression" ...
find out what number it all boils down to. I don't think you'll have
any trouble with that now.
Answer:
Draw a figure!
There are 6 surfaces to add.
4 of them have area 9*5 and 2 have area 5*4.
You should be able now to compute the surface areas.

The ratio of mixture of sand and cement is 5:3
If the total volume of mixture is 
Suppose there is 5x and 3x cubic centimeter of sand and cement respectively i.e.
Sand 
So, there is of sand in the mixture
Each number is increased by ten... umm idk any other answer you want
Answer:
Step-by-step explanation:
For this problem, it says that the company not only shipped packages, but also bought a number of stamps. From the equation 6.70+0.50x, it's fairly easy to say that 6.70 is the packages,
What's not so easy is figuring out whether or not 0.50 is the stamps, or x is. However, there's an easy way to figure it out!
From this one, we would have to use "common sense" (not my words, someone elses). Using "common sense", we have to think, can someone buy 0.50 of a stamp?
Technically yes... But would someone buy 0.5 of a stamp? Not really.
So we can safetly assume that x is the "stamp", and 0.50 is <em>the cost of the stamp</em>.
Hope this helps!
