-b = 12.5 : multiply both sides by -1
-b x -1 = 12.5 x -1
b = -12.5
Alternatively,
-b = 12.5 : add b to both sides
-b + b = 12.5 + b
0 = 12.5 + b : subtract 12.5 from both sides
-12.5 = 12.5 + b - 12.5
-12.5 = b
Sorry but i dont know te answer to this :( x/a= y/b therefore x = ay/b
B equals the area of the base.
a=24 b=16 c=18
1 is the answer. -(-4)- 3 = 4-3 = 1 .
b= 4
Yes.
2a. (a, b and c are all equal.)
No, they are not equal sets.

B equals the area of the base.
They all equal each other. a = b = c = d = e e = a e = b e = c e = d e = e
b=12
2
a=24 b=16 c=18
By utilising the fact that subtraction is the reverse operation to addition. Thus, if A + B = C then C - B = A In this particular case, since 125 + 150 = 275 then 275 - 150 = 125
1 is the answer. -(-4)- 3 = 4-3 = 1 .
b= 4
