Let the number = x
Given: The sum of -5 and a number is -15
Then,
x - 5 = -15
or x = -15 +5 = -10.
Hence, the number is -10

now, "A" is the accumulated amount, including the earned interest, how much interest was it earned? well, is just A - P.
No expressions are showing to choose from, but it should look like:
A= amount of money earned
m= # of miles driven
Amount earned equals $6 plus ($0.45 times the # of miles driven.)
EQUATION:
A= $6 + $0.45m
Hope this helps! :)
The number is 7 because of the transitive property of addition
Answer:
y - 5= 5(x-x)
Step-by-step explanation:
Point slope form is y - y(1) = m( x- x (1))
So just put in the information the question gave you
y - 5= 5(x-x)
If you have x, just put the x in the x(1) spot and you're set!
Hope this helped! :)
