Question

What value of r makes the equation true?

r + 0.27 = –0.59









A.
–0.86







B.
–0.32







C.
0.32







D.
0.86

Answer 1

The answer would be A. -0.86 because if you plug in -0.86 for r then add -0.86 and 0.27 then you would get the correct answer which would be -0.58. :)

Answer 2

You subtract 0.27 from both sides
r=-0.59-.27
.59-.27=-.86
R=-0.86
The answer is A
