Clara simplifies (8b--r) and says the result is 6b-5r. what error did clara make? asap only have 15 mins left

Clara makes error after opening the bracket she did not changes the sign of  r .

Correct simplification of  (8b-4r)-(2b-r) is 6b- 3r .

Step-by-step explanation:

As given the expression in the question be

= (8b-4r)-(2b-r)

Open the bracket

= 8b - 4r - 2b + r

Solving the above

= 6b - 3r

Clara makes error after opening the bracket she did not changes the sign of  r .

Therefore the correct simplification of  (8b-4r)-(2b-r) is 6b- 3r .

i would have to say it is c.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
