The sum of two numbers is -9. Which expressions could represent the addition problem?
PLEASE HELP
Answers
The answer is B all the others basically go into positive
A cannot be right because -10 -1 is -11
B has to be right because -10 + 1 is -9
C cannot be right because 10 - 1 is 9, but it’s positive
D cannot be right because 10 + 1 is 11
Remember if you have 2 negatives it’s positive, and if you have 1 negative and 1 positive it’s negative

Imagine that you take a road trip from A to D, but you have to do it in segments. Let’s say the distance from A to B is 145 miles; from B to C is 160 miles, and C to D is 115 miles. It takes you 6 hours to drive from A to D. What was your average speed (in miles per hour) during your trip from A to D? (Hint: How many miles did you drive from A to D? Then divide the total miles by the number of hours).
Answers
Answer: The average is 70.
Step-by-step explanation:
145+160+115=420
420 divided by 6 =70
So the average is 70.

find three consecutive integers whose average is 20. please show work!!
Answers
Answer:
19,20,21
Step-by-step explanation:
The average is 20. The numbers can be written as: 20+a, 20 +b, 20+c, with a, b, c integers (positive and negative, but higher than - 19),with a+b+c =0.
You have to find the combination a, b, c with the smallest positive integer as its higher number.
Obviously, you start with 1, and find - 1,0,+1 as a suitable solution.
Therefore, the numbers are 20-1, 20,20+1
=> 19,20,21

Converting percentages to decimals has you divide the percentage by 100.
So our first equation is full price minus a tenth of that price, leaves you with nine tenths, right? Then we multiply that nine tenths by 8 percent, which is 8 hundredths.

B. y = 5x
Step-by-step explanation:
there are 2 coordinates (0,0) and (3,15)
slope m = (y2-y1)/(x2-x1)
m = (15 - 0)/(3 - 0) = 15/3 = 5
Using y = 0, x = 0, m - 5
y = mx + b
0 = 5(0) + b
b = 0

Answer:
B. or -16
Step-by-step explanation:
First, find what |-3-(-1)| is equal to.
|-3-(-1)|
= |-3+1|
= |-2|
= 2
|-3-(-1)|=2
Now we find x (I find it easier to substitute the question mark with a variable)
x÷-8=2
Lets go through our values, or answer choices:
-32/-8 = 4
This cannot be the answer
-16/-8=2
This is the correct answer.
So...
-16÷-8=|-3-(-1)|
They are equal because both sides equal 2.
