I am looking for 3 consecutive multiples of 7. The sum of the squares of the 2 smallest is 147 less than the square of the largest. The first multiple of 7 is $(x - 7)$ , the 2nd multiple of 7 is (x), and the 3rd multiple of $7 (x + 7)$ . Find the numbers.

Ben and Carl are remembering how you told them that a 0 at the end of a whole number makes it ten times greater. They remember that 420 is ten times bigger than 42, for example. They wonder if the same thing works with decimals. Ben argues that putting a 0 at the end of a decimal number makes it ten times greater. Carl says, "No. You've gotta sneak it in right after the decimal point and push everything to the right." How do you help them to see what's true and what's not?

Let U $= {1, 2, 3, . . ., 2400 }$
Let S be the subset of the numbers in U that are multiples of 3, and let T be the subset of U that are multiples of 7.
Since $2400 \div 3 = 800$ , it follows that $n (S) = n ({3 \cdot 1, 3 \cdot 2, \dots, 3 \cdot 800}) = 800$ .
(a) Find n(T) using a method similar to the one that showed that $n (S) = 800$ .
(b) Find $n (S \cap T)$ .
(c) Label the number of elements in each region of a two-loop Venn diagram with the universe U and subsets S and T.
Questions:Find n(T) ? Find n(SnT)

Getting your pre Algebra solved becomes much easier when you have all the answers to your questions by taking a closer look at the various examples dealing with Pre-Algebra subjects. We have intentionally collected the list of pre-algebra equations and various solving equations with decimals problems to help you see various examples that explain how certain solutions are found. Still, if something sounds unclear or you are concerned about some solution that has been provided, approach pre-algebra with reverse engineering approach (going backwards).
