Answer:
x = 12
y = -29
Step-by-step explanation:
Our given equations: x + y = -17 and x - y = 41
Solve for x and substitute.
x = -17 - y
(-17 - y) - y = 41
-17 - 2y = 41
2y = -58
y = -29
Solve for x using y
x + (-29) = -17
x = 12
Answer:
Yes! There are 3 different explanations I have. Pick your favorite.
Step-by-step explanation:
So we are asked to see if the following equation holds:
The units cancel out ft/ft=1 and sec/sec=1.
So we are really just trying to see if 4/6 is equal to 12/18
Or you could cross multiply and see if the products are the same on both sides:
Cross multiply:
Since you have the same thing on both sides then the ratios given were proportional.
OR!
Put 4/6 and 12/18 in your calculator. They both come out to have the same decimal expansion of .66666666666666666(repeating) so the ratios gives are proportional.
OR!
Reduce 12/18 and reduce 4/6 and see if the reduced fractions are same.
12/18=2/3 (I divided top and bottom by 6)
4/6=2/3 (I divided top and bottom by 2)
They are equal to the same reduced fraction so they are proportional.
The answer is 20 4/36=20/180
Answer:
1) 12 - 8/3 = ((12*3)-(8))/3 = 28/3
2) 10/ (4/7) = (10/1)*(7/4) = 70/4
3) 12/5 + 4/6 = ((5*4)+(12*6))/(5*6) = 46/15
The interior angles of any convex quadrilateral add up to 360º in measure.
This means angle 1, whose measure is 42.5% of this total, has measure 0.425*360º = 153º.
Similarly, angle 2 has measure 0.075*360º = 27º, and angle 3 has measure 0.175*360º = 63º.
So
153º + 27º + 63º + <em>x</em>º = 360º ==> <em>x</em> = 117
