Can any body help with the word problems

1 answer:

6 0

Answer:

1) 8x - 9

2) 5x - 2

Step-by-step explanation:

1) Given 8 times the difference between a number x and 9.

This means we should have: $8(x - 9)$

Now using the distributive property we distribute 8 to x and 9 like:

$8x - 72$ . Thus the answer.

For 2) All the expressions except 4 equals $5x - 10$ . The last option is $5x - 2$ . Thus the answer.

For this case we have that the commutative property establishes that the order of the factors does not alter the product. Example:

$5 * 6 = 6 * 5\\4 + 3 = 3 + 4$

Then we have the following options illustrate the property:

$3 + 4 + 6 = 3 + 6 + 4 = 13\\9 * 2 * 7 = 7 * 9 * 2 = 126\\2 + 3 + 1 = 3 + 1 + 2 = 6\\5 + 2-4 = 5-4 + 2 = 3$

It is necessary to emphasize that option b illustrates the associative property and in option c equality is not fulfilled

Option A, D, E, F

He is incorrect because each number is in a different place and those different places are worth more or less than the other places
