Step-by-step explanation:
n - 9
This is because, it is somewhat telling you to subtract 9 from a "n" number, such words as "less than" give signs to tell you to subtract!

This question is asking for the value of two numbers, which we can label as:
#1 = x
(Any value we do not know can be represented with a variable)
#2 = 3x + 2
("2 more" means + 2, and "3 times" means multiply by 3. The "another" is the variable we talked about before. Combining everything we have 3x + 2).
The last piece of information we are given is that the sum of the two numbers is 22. The word sum indicates that we need to add the two numbers, and when they added they will equal the integer 22.
(x) + (3x + 2) = 22
x + 3x + 2 = 22
Combine like terms
4x + 2 = 22
Subtract 2 from both sides
4x = 20
Divide 4 from both sides
x = 5
This sole value of "x" already gives us the value of the first number. Since our second number is "3x + 2", all we have to do is plug in the value of x into the expression.
3x + 2 = 3(5) + 2 = 15 + 2 = 17
The second number is 17.
Final Answer: The two numbers are 5 and 17.
(If you want to check, add the two numbers and make sure they add up to 22 and multiply 5 by 3 and add 2.)
Answer:
0.58
Step-by-step explanation:
The first approach to solving the question above is to find the product of 0.3 and 0.4 thus:
Next step is to find the sum of 0.3 and 0.4 thus:
The final step is to find the difference between the two results. Thus:
Therefore, the product of 0.3 and 0.4 subtracted from the sum of 0.3 and 0.4 is 0.58
