Answer: b=5

Step-by-step explanation:

Multiply all terms by b and cancel:

3b/5+2=1b

3/5b+2=b(Simplify both sides of the equation)

3/5b+2−b=b−b(Subtract b from both sides)

−2/5b+2=0

−2/5b+2−2=0−2(Subtract 2 from both sides)

−2/5b=−2

(5−2)*(−25b)=(5−2)*(−2)(Multiply both sides by 5/(-2))

b=5

Check answers. (Plug them in to make sure they work.)

b=5 (Works in the original equation)

Answer:

b=5

Hope this helps! ;)

If the numbers -2.5, -1.6, -3 1/10, - 1/10, and -0.5 were graphed on a number line, which would appear farthest to the left?
Leona [35]
Turn the question around.
If all the numbers were positive: 2.5, 1.6, 3 1/10, 1/10, and 0.5, which would be farthest to the right?

The fact is that the negative numbers are a reflection of the positive numbers.
Since 3 1/10 would be farthest to the right with positive numbers, -3 1/10 will be farthest to the left with the negative numbers.
