Answer:
I didn't understand your question so i need to do like this . choose the correct one
X= 10.18
10x = 101.8
100x = 1018.8
100x-10x = 917
x = 917/90
Answer:
Total distance = 30.3 units
Step-by-step explanation:
Coordinates for the location of Alanah, Mia, Teresa and Arena are,
Alanah → (2, 8)
Mia → (8, 16)
Teresa → (8, 2)
Arena → (14, 4)
Distance between two points
and
is given by the formula,
d = 
Distance between Alanah and Mia = 
= 
= 10 units
Distance between Mia and Teresa = 
= 14 units
Distance between Teresa and Arena = 
= 
= 6.3 units
Total distance of Alanah's trip to Arena = 10 + 14 + 6.3
= 30.3 units
(x-7)(x-5)=x-7
(x-7)(x-5)-(x-7)=0
(x-7)[(x-5)-1]=0
(x-7)(x-6)=0
x=7 or x=6
Hope this can help.
