Solve the following<br> 5 3/4 + (6 2/3 - 4 5/6) =
chubhunter [2.5K]

Answer:

7 5/12

Step-by-step explanation:

first, subtract 4 5/6 from 6 2/3 by converting 6 2/3 to 6 4/6

5 3/4 + (6 4/6 - 4 5/6) = 5 3/4 + 1 4/6

* I borrowed 6/6 or '1' from the 6 and made 4/6 into 10/6

5 3/4 equals 5 9/12 and 1 4/6 equals 1 8/12

adding them gives you:

6 17/12 which is the same as 6 + 1 5/12, or 7 5/12

25,812-4.2d=31.311-5.5d
Bas_tet [7]

Let's solve your equation step-by-step.

25812−4.2d=31.311−5.5d

Step 1: Simplify both sides of the equation.

25812−4.2d=31.311−5.5d

25812+−4.2d=31.311+−5.5d

−4.2d+25812=−5.5d+31.311

Step 2: Add 5.5d to both sides.

−4.2d+25812+5.5d=−5.5d+31.311+5.5d

1.3d+25812=31.311

Step 3: Subtract 25812 from both sides.

1.3d+25812−25812=31.311−25812

1.3d=−25780.689

Step 4: Divide both sides by 1.3.

1.3d

1.3

=

−25780.689

1.3
