For 5a+5b+5c=-20

A= -4 - b - c

B= -4 - a - c

C= -4 - a - b

———————————

4a+3b+3c=-6

A= -3/2 - 3b/4 - 3c/4

B= -2 - 4a/3 - c

C= -2 - 4a/3 - b

———————————

-4a+3b+3c=9

A= -9/4 + 3b/4 + 3c/4

B= 3 + 4a/3 - c

C= 3 + 4a/3 - b

The sum of two numbers is 49 and the difference between these two numbers is 9. What are these two numbers?​Shown working out pl
8_murik_8 [283]

Let numbers be x and y

ATQ

  • x+y=49---(1)

  • x-y=9---(2)

Adding both

\\ \sf\longmapsto 2x=58

\\ \sf\longmapsto x=\dfrac{58}{2}

\\ \sf\longmapsto x=29

Now putting value in eq(2)

\\ \sf\longmapsto x-y=9

\\ \sf\longmapsto 29-9=y

\\ \sf\longmapsto y=20

Find the sum of the geometric series: <br>32 - 8 + 2 - 1/2 +...
ZanzabumX [31]
Time to work it out 
32 - 8 + 2 - 1/2
32 - 8 + 2 = 26
now you have
-1/2 + 26 
so we convert 26 to fraction form to subtract 
26/1 - 1/2
we must find the common denominator
52/2 - 1/2
51/2
fifty-one over 2 (fraction) is your answer! :)
