The answer is :-
If x+y=20
And 2:3
Then by trial and error method
8+12=20
Cancelleing...
8/12=2/3
Which is similar to 2:3
Therefore the smallest number is 8
The initial value will be 30 while the rate of change. is always attached to the variable which is 0.02
<h3>Function and rate of change</h3>
The rate of change of an expression is also known as the slope of the equation
Given the function that represents y charges for service as shown below
C = 30 + 0.02n
where n is the number of minutes talked, and C is the monthly charge, in dollars.
From the given function, the initial value will be 30 while the rate of change. is always attached to the variable which is 0.02

Answer:
36.5 square units
Step-by-step explanation:
There are a number of ways to compute the area of a polygon from the coordinates of its vertices. There are algebraic formulas, geometric methods involving decomposing the figure, and an interesting method described by Pick's theorem.

<h3>Geometry</h3>
The figure can be enclosed by a rectangle that is 7 units high by 9 units wide. The actual figure is obtained by removing the triangular corners of this rectangle. The areas of those are given by the triangle area formula ...
A = 1/2bh
Working clockwise from lower left, the triangle base (horizontal) and height (vertical) dimensions are 5×6, 7×1, 2×6, 4×1. That means the area of the triangles is ...
A = 1/2(5×6 +7×1 +2×6 +4×1) = 1/2(30 +7 +12 +4) = 1/2(53) = 26.5
The area of the bounding rectangle is ...
A = bh = 9×7 = 63
So, the area of the figure is the difference ...
A = 63 -26.5 = 36.5 . . . square units

Answer:
x = - 10
Step-by-step explanation:
Average is calculated as
average =
, thus
= 3
Multiply both sides by 3 to clear the fraction
19 + x = 9 ( subtract 19 from both sides )
x = - 10
Answer:
units
Step-by-step explanation:
The zero (0) is in the units place. unit = 1
