You need to put the Answers and picture/problem before asking someone to answer it.
Answer:
Solutions:-5,0,9,6
Not solutions: 12.5,10
Explanation:
The inequality that was given is:
20 > 5 + 3x
First, group similar terms;
20 - 5 < 3x
15 < 3x
x = 5
Thus, the solutions are:-3.5, 5, 4 3/4, -15
The not solutions are:-10 2/3, 129,
Hope this helps! :)
The other 6 books can be arranged in 6 ways
= 6*5*4*3*2*1 = 720 ways answer
The associative law states that it doesn't matter how we group numbers when we add and/or multiply. So we could rearrange the brackets and parentheses to get the equivalent equation:
9m(6+n)
Both equations total:
54m+9mn
(I applied the distributive property to solve it).
