Question

50 POINTS!!
JUST THE ONES CIRCLED!!

Answer 1

B = 60

Explanation:

Step 1: Simplify both sides of the equation.

4/5b+6=9/10b

Step 2: Subtract 9/10b from both sides.

4/5b+6-9/10b=9/10b-9/10b

-1/10b+6=0

Step 3: Subtract 6 from both sides.

-1/10b+6-6=0=6

-1/10b=-6

Step 4: Multiply both sides by 10/(-1).

(10/-1)*(-1/10b)=(10/-1)*(-6)

Answer 2

Step 1: Simplify both sides of the equation.

4/5b+6=9/10b

Step 2: Subtract 9/10b from both sides.

4/5b+6-9/10b=9/10b-9/10b

-1/10b+6=0

Step 3: Subtract 6 from both sides.

-1/10b+6-6=0=6

-1/10b=-6

Step 4: Multiply both sides by 10/(-1).

(10/-1)*(-1/10b)=(10/-1)*(-6)

answer: b=60
