5 is a prime number, its only factors are 1 and itself
The solution is x = 2 , y = 3.5
<h3>What is Equations?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign
Given:
2y= - x+9 ......................( 1)
3x-6y=-15 ........................ (2)
From (1),
x = 9 - 2y ........................... (3)
Put x = 9 - 2y into (2) , then becomes :
3 ( 9 - 2y ) - 6y = - 15
27 - 6y - 6y = - 15
27 - 12y = - 15
27 + 15 = 12y
42 = 12y
y = 3.5
Now, put y = 3.5
x = 9 - 2y
x = 9 - 2 (3.5 )
x = 9 - 7
x = 2
Hence, x = 2 , and y = 3.5.

Two consecutive numbers can be written as:
x , x+1
So their sum being 141
x + x +1 = 141
Combine and solve for c
2x = 140
x = 70
So two numbers are:
70,71
If you find the circumstance using the new radius, then the circumf will be longer than 15ft
I didnt have room for 7 so ill just write it here
20O-12x<60
-12x<-140
X>11.6666..or 11 2/3
