The answer is A: 4/3=DE/9
4 is corresponding to line DE
3 is corresponding to 9
Not necessarily, it could be either the numerator or the denominator. For example, -3/4 (lets pretend that its one on top of the other) either the three or the four could be negative but not both. If both the numerator and denominator were negative, they would cancel each other out, making it a positive question. So to answer your question, it is no.
Let
x = measure of the angle
y = measure of the supplement
By definition of supplementary, the two angles add to 180 degrees, so
x+y = 180
This is the first equation.
The second equation is y = 3x-16 since we're given the info that "the supplement is 16 degrees less than three times the angle"
--------------------------
The system of equations is
x+y = 180
y = 3x-16
Focus on the first equation x+y = 180, plug in y = 3x-16, and solve for x
x+y = 180
x+3x-16 = 180 ... y is replaced with 3x-16
4x-16 = 180
4x-16+16 = 180+16
4x = 196
4x/4 = 196/4
x = 49
Because x = 49, we can use this to find y
y = 3x-16
y = 3*49-16
y = 147 - 16
y = 131
-------------------------------------------------------------
Final Answers:
The measure of the angle is 49 degrees
The measure of the supplement is 131 degrees
Answer:
246
Step-by-step explanation:
next time use a calculator
divide 492 by 2 and you get 246
divide that by 2 and you get 123
and divide that by 3 and you get 41
12/16, 7/16, 10/16 (not simplified, just with LCD);The LCD of the 3 fractions is 16 (from denominators) so all we have to do is multiply both the numerator by the same number that multiplies with the denominators to get 16. We leave 7/16 alone since it already has denominator of 16.
3/4 * 4 = 12/16
5/8 * 2 = 10/16
