(x – 8)² + (y – 9)² = 14
</span>are the correct answers
Answer:
500 times
Step-by-step explanation:
They breathe 20 times per minute for 25 minutes
20(times per minute) x 25(minutes) = 500
The answer is 76% because 19/25=.76
Ok so the first step would be to distribute 3 into 3x and -6. So 3 times 3x would be 9x. 3 times -6 is -18.
the equation now is
18 = 9x - 18
Now you would have to do inverse operation
18 = 9x - 18
+18 +18
36 = 9x
Now you would divide 9x into 36 to isolate the variable
36 / 9x = 4
x = 4
