Answer: idk sorry
Step-by-step explanation:
7:45-5:51 gives you the difference in times remember 60sec per min (1:54)
turn it into only seconds so 60+54=114s and 7x60+45=645s
114/645 gives you the percentage of difference
Okay so first what you would do is figure out what 3/5 is as a decimal so you would divide 3 by 5 which is 0.6 so the percentage is 15.6%
Next turn it into a fraction which would be 15.6/1
Then multiply the numerator and denominator by 10
15.6= 15.6/1= 156/10
then to put it in simplest form divide 10 by 156 and that would be 15 and 6/10
hope this helped (;
I think it should be 90° since x is a right angle
Answer:
(3, 12)
Step-by-step explanation:
x + y = 15
x - y = -9
add them together
2x + 0y = 6
2x = 6
x = 6/2
x = 3
substitute 3 into any equation, i chose x + y = 15
3 + y = 15
y = 12
check for 2nd equation:
3 - 12 = -9
-9 = -9
