Answer:
Step-by-step explanation:
The answer is B because 5 times x is 5x and 5 times 6 is 30. Since there is a subtraction sign, it would be equal to 5x-30
Answer:
a) 3/5 < 4/5
b) In general if two fractions have the same denominator, then whichever fraction has the numerator closer to its denominator will be the largest fraction.
c)
<em>or</em> 
Step-by-step explanation:
a) 3/5 < 4/5
Flip the sign and the placement of the fraction so 3/5 is less then 4/5.
b) In general if two fractions have the same denominator, then whichever fraction has the numerator closer to its denominator will be the largest fraction.
c) We need to change the denominators to a common denominator to compare the size of the two fractions:
×
= 
×
= 
The common denominators of the two fractions is 30. Comparing the two fractions:
<em>or</em> 
so we get:
<em>or</em> 
Answer: 
You can write this as (-infinity, 7) if you aren't able to use the infinity symbol.
====================================================
Explanation:
Think of x < 7 as writing 
So x is between negative infinity and 7, excluding both endpoints.
To write
in interval notation, we write
The curved parenthesis tell us to exclude the endpoint.
Hello there!
Answer:
$24
Step-by-step explanation:
In order to find the answer to your problem, we're going to need to find out how much ONE liter of paint costs.
Lets gather the information of what we know:
2 1/2 liters of paint
↑ Cost $60.
With the information we know, we can solve to find the answer.
In order to get the answer, we would need to divide 60 by 2 1/2 (or 2.5). We would need to do this because when we divide it, it would allow us to get the cost for 1 liter.
Lets solve:

When you divide, you should get the answer of 24.
This means that one liter of paint cost $24.
$24 should be your FINAL answer.
