We know that angle 101 and its interior angle next to it will equal 180 because it's a straight line.
180-101= 79 degrees
Find 3rd angle of triangle.
180= 38+79+y
180= 117+y
Subtract 117 from both sides
63= y
That is the interior angle by x. X plus 63 also equal a line, or 180 degrees.
180= 63+ x
Subtract 63 from both sides
117= x
Hope this helps! :)
11/16..." / " means divide....= 0.6875
0.688
when comparing, if it makes it easier, line ur decimals up and put a zero in any empty spaces...
0.6875
0.6880 (this is the same as 0.688)
so the one that is bigger is : 0.688 <==

Answer:
we will mix 55 liters of 20% solution and 20 Liters of 50% solutions.
Step-by-step explanation:
let the 20% solution = x liters
let the 50% solution = y liters
total solution of the mixture of the two solutions in % = 28%
total solution of the mixture of the two solutions in liters = 75 liters
considering the total solutions given, we will have the following equations if we mix the solutions in equal proportion;
20x + 50y = 28 (75)
0.2x + 0.5y = 0.28(75)
0.2x + 0.5y = 21 -------equation 1
Also,
x + y = 75 ------equation 2
y = 75 - x
(substitute this into equation 1)
0.2x + 0.5(75 - x) = 21
0.2x + 37.5 - 0.5x = 21
0.2x - 0.5x = 21 - 37.5
-0.3x = -16.5
x = -16.5 / -0.3
x = 55 liters
Recall, y = 75 - x
y = 75 -55
y = 20 Liters
Thus, we will mix 55 liters of 20% solution and 20 Liters of 50% solutions.
X/3 > 7 <== ur equation
multiply both sides by 3
x > 7 * 3
x > 21 <== ur solution
