Answer:
The correct answer is B.) (4x - 7 + 5x + 5) and (9x + 12).
An ordered pair such as (3,-1), is a shorthand way of writing two variables, such as x = 3 and y = -1. The order of the numbers in the pair is important: x always comes before y.
An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses.
It helps to locate a point on the Cartesian plane for better visual comprehension.
The numeric values in an ordered pair can be integers or fractions.
Ordered Pair = (x,y)
Where, x = abscissa, the distance measure of a point from the primary axis “x”
And, y = ordinate, the distance measure of a point from the secondary axis “y”
In the Cartesian plane, we define a two-dimensional space with two perpendicular reference lines, namely x-axis and y-axis. The point where the two lines meet at “0” is the origin.

Hi there
The formula is
A=p (1+rt)
A ?
P 300
R 0.02
T 3 years
So
A=300×(1+0.02×3)
A=318
Hope it helps
2(n+4) + 6 = (1/2)(3-n)
Then 2n + 8 + 6 = 3/2 - n/2
and 2n + 14 = 3/2 - n/2
(5/2)n = 3/2 - 28/2 = -25/2
-25/2
n = -------------- = -5 (answer)
5/2
Two 2.5 pound bags = 5 pounds for $34.99
34.99/5 pounds = 6.998 or $7/pound
