(2,13) is a solution to the equation y=3x+7.
Answer:
LBC is 75 degrees
Step-by-step explanation:
When you follow the angle measurements from the first and when one line equals 180, figuring out the other angle measurements can determine the answer for LBC.
Take a better picture for me
2x-y=11 ,6x-3y=15
4x+4y=26
-4y. -4y
4x=22
4. 4. divided
x=5.5 if its wrong and fix something that's wrong
He bikes 15 miles which is 10 times more than he swims. He runs 9 miles which is half of what he bikes 15/2=7.5. Plus the addition 1.5 miles which is 9. He swims .10 of what he bikes which is 15x.10 which is 1.5 . So he swims 1.5 miles.
Bikes = 15 miles
Run= 9 miles
Swim= 1.5 miles
Add all of them and you get 25.5 which the total amount of miles for his training that day.
