Multiply 100•21. Divide that by how many minutes are in a week.
$10 :) I hope this helps!
Answer:
In the first case x and y be 49 and 47 respectively
In the second case x and y be 41 and 37 respectively
Step-by-step explanation:
Let us assume the two number be x and y
In the first case
Now
x + y = 96
x - y = 2
2x = 98
x = 49
y = 49 - 2 = 47
So x and y be 49 and 47 respectively
In the second case
x + y = 78
x - y = 4
2x = 82
x = 41
y = 78 - 41 = 37
So x and y be 41 and 37 respectively
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.
Answer:
92°
Step-by-step explanation:
The exterior angle is equal to the sum of the 2 opposite interior angles, that is
2x - 2 = x + 45 ( subtract x from both sides )
x - 2 = 45 ( add 2 to both sides )
x = 47
Then
exterior angle = 2x - 2 = 2(47) - 2 = 94 - 2 = 92°
