12. the reflexive property of congruence means anything is congruent to itself
13. the transitive property of equality means if 2 things are equal to the same other thing then they are equal to each other
14. Symmetric property of equality means that you can change the order of the equation
15. That's the transitive property of congruence its basically the same as 13 but with segments instead of the measure of angles.
She drives at a rate of 75 miles per hour for three hours, so the first thing you'd do is 75 x 3.
75 x 3= 225
So, she traveled 225 miles to the airport.
Then, she travels at a rate of 400 miles per hour for 4 hours.
4 x 400 = 1,600
That's 1600 miles she traveled from the airport to her destination.
Now to find the total number of miles traveled, add 1,600 and 225.
Total distance traveled: 1825 miles.
51-9= 42
42/3= 14
your answer would be 14 friends
CHECK:
3*14= 42
The value of x is 5/6 and y is 8/5.
Step-by-step explanation:
Given,
12x+15y=34 Eqn 1
-6x+5y=3 Eqn 2
Multiplying Eqn 2 by 2
Adding Eqn 1 and 3
Dividing both sides by 25
Putting y= 8/5 in Eqn 1
Dividing both sides by 12
The value of x is 5/6 and y is 8/5.
