Answer:
142
Step-by-step explanation:
It said to sort it from least to greatest and you did, so we don't need to worry about that. It said ''<u>find the median of the numbers</u>'', which is 137 and 147. Because there are <em>two numbers</em>, we need to work out <em>the middle number</em> of them two.
We start off <em>finding the difference</em> between them <em>which is 10</em> and the middle number of 10 (5). So we just add 5 to 137 (or subtract 5 from 147) which gives us the answer 142
60+53=180
113=180
-113 -113

Answer X=113
Answer:
x=-6, y=-8. (-6, -8).
Step-by-step explanation:
8x-5y=-8
-7x-5y=82
---------------
-(8x-5y)=-(-8)
-7x-5y=82
---------------------
-8x+5y=8
-7x-5y=82
---------------
-15x=90
x=90/-15
x=-6
8(-6)-5y=-8
-48-5y=-8
5y=-48-(-8)
5y=-48+8
5y=-40
y=-40/5
y=-8
