Step-by-step explanation:
Question written clearly below:
Which answer choice is equivalent to the expression below?
-7(2+n)+1/3(-9-6n)
a.-17 -9n
b, -14-12n
c. 11+5n
d. 14+2n
Solution
-7(2+n)+1/3(-9-6n)
Open parenthesis
(-14-7n)+(-9/3-6/3n)
= -14-7n+(-3-2n)
= -14-7n-3-2n
Collect like terms
= -14-3-7n-2n
= -17-9n
The answer is option a. -17 -9n

This relation is <u>injective</u>, meaning it is a one-to-one function.
Answer:
Step-by-step explanation:
So it's basically an extra special complicated addition problem. Let's take it step by step.
We'll call the books book A, B and C. Well we know Book A has 120 more pages than book B, so if we say book B has x pages, then book A has x +120 pages.
Then we know that x is 75 less than the third, so we can say book C has x + 75 pages. So in order the number of pages each book has are
A = x + 120
B = x
C = x + 75
We also know A + B + C = 1005. Can you handle it from there? Or is there anything you don't understand?
