we have the numbers
we know that
The sum of a number and its additive inverse is 0
so
therefore
the number n is equal to
the sum is equal to zero
the answer Part a) and Part b) in the attached figure
Answer:
books.
Step-by-step explanation:
We have been given that Hannah's school hosted a book donation.
Total number of students = 150.
Total number of books donated by all students = b.
Since we know that average is calculated by dividing the sum of the values in the set by their number.
Since we are told that Hannah donated 3 times as many as the average number of books each student donated. So books donated by Hannah will be:
Upon simplifying we will get,
Therefore, Hannah donated books.
Answer:
C
Step-by-step explanation:
5a + 18 < -27
5a < -45
a < -9
Graph C matches the solution set of this inequality.
7x + 3x + 5
Combined like terms, in this case “x”
7x + 3x = 10x
5 does not have a like term so it stay by itself
Answer 10x +5
I know this answer because I am like that 4 sqrt 2
