Answer:
78
Step-by-step explanation:
even numbers are numbers that end in 0, 2, 4, 6, or 8. these numbers can be considered even because they would <em>even</em>ly split between a group of 2
the "sum" of a group of numbers is the numbers added together
So, the numbers between 23 and 29:
23, 24, 25, 26, 27, 28, 29
(even numbers are in bold)
if we add these numbers together,
{1} {carry the 1 from the 18 in the one's place}
24
26
+ 28
______
78
So the sum of all the even numbers between 23 and 29 is 78.

In 100 flights 86 get to the destination on tima.
In four, 3 flights get on time. So the probability of four in five flights get on time is of 14%.
Here are some equations
2x=14
8x+4=60
3x+10=5x-4

Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2
The perimeter of the polygon is 26.1 units.
To find the perimeter of the polygon.
<h3>What is polygon?</h3>
A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.
Given that:
Distance between points 
, 
is given by
As per the graph,
point Q is (2,0)
point R is (4,5)
point S is (8,7)
point T is (6,4)
point U is (10,3)
QR=
RS=
ST=
TU=
QU=
Perimeter refers to sum of lengths of all the sides.
Perimeter =5.38+4.47+3.60+4.12+8.54=26.1 units
So. the perimeter of the polygon is 26.1 units.
