3) What is the *SUM* of consecutive numbers from 187 to 325 ?.
Have a best luck.

Answer 1

Answer:

The value of a = d = 7, b = 9, c =19.

16 ÷ 4(4) =1

Answer 2

Step-by-step explanation:

answer for 1st question only

a+b=16

a=16-b

a+c=26

16-b+c=26

-b+c=10

-b=10-c;b=-10+c

a=16-b;=16-(-10+c)=26+c

c-d=12;;;c=12+d

a=26+12+d

a=38+d

b=-10+d+12

b=2+d

a+b=16

2+d+38+d=16;;;2d+40=16;;d= -12

c-d=12 c--12=c+12=12 c=0

a+c=26

a=26

b= -10
