Using the midpoint concept, it is found that the value of a is of a = 2.
<h3>What are the coordinates of the points?</h3>
Researching this problem on a search engine, the coordinates are given as follows:
<h3>What is the midpoint concept?</h3>
The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
Hence the following system of equations can be built:
(b + 1 + 2a)/2 = 3.
b + 1 + 2a = 6.
b = 5 - 2a.
(a + 2 + 3b + 3)/2 = 5
a + 3b + 5 = 10
a + 3b = 5.
Since b = 5 - 2a, we have that:
a + 15 - 6a = 5.
5a = 10
a = 10/5
a = 2.
The value of a is of a = 2.

Answer:
How is DC 12 units if all the sides are congruent and AB clearly states that it is 9 units long?
Doesnt make sense
1 and three fourths is larger because it would be 1.35 as a decimal and the other would be 1.625
Answer: 9
Step-by-step explanation:
Let the consecutive odd numbers be y, y+2 and y+4.
Five times the smallest of three consecutive odd integers is seven more than twice the largest. Find the largest integer can be expressed as:
5y = 2(y+4) + 7
5y = 2y + 8 + 7
5y = 2y + 15
5y - 2y = 15
y = 3
The smallest odd number is 5
The largest integer will be:
= y + 4
= 5+4
= 9
