Answer:
u= -3 v=11
Step-by-step explanation:
7u+2v=1 17u+6v=-9
-3(7u+2v=1)= -21u-6v=-3
-21u-6v=-3 + 17u+6v=-9 = -4u= -12
u=-3
7(-3)+2v=1
-21+2v=1
2v=22
v=11
Do you have a picture with the problem and instructions? I can help but I need to see it
Given, distance between South Carolina and Texas = 
Distance between Texas and California = 
Let's assume, both the distance is same.

=> 
=> 
=>
Plug x = 113 in 
Miles.
Similarly,
miles
Since 2500 divided by 2 = 1250 miles, hence our assumption was correct, Texas lies between both the cities.
10 because 8 squares plus 6 squared equals 100 and the root of 100 is ten
