Step-by-step explanation:
slope equals to change in y/change in x
slope=7-3/4+4
=4/8=1/2
Resolve to do so
5x3=15
5x9=45
3+9=12
15+45=5x12
15+45=60
5x12=60
60=60
Which property is shown I did not understand but I think with the result 60 = 60 alone, but you will understand if you can not send me a comment, so I'll try to make you understand =)
Speed = distance / time
7 = 17.5 / t
t = 17.5 / 7
= 2.5 minutes
Rational numbers are numbers that can be turned into a fraction. They can be negative or positive.
Integers are whole numbers. They can be negative or positive.
Numbers such as 0.10 are rational because they can be turned into a fraction
0.10 = 1/10....and since it is not a whole number, it is not an integer.
<u>Answer-</u>
<u>Solution-</u>
From the attachment,
AD = AE, so FA is a median.
BD = BF, so BE is a median.
CF = CE, so DC is a median.
And G is the centroid.
From the properties of centroid, we know that
The centroid divides each median in a ratio of 2:1
So,
So, GB will be 
units
