what is the value of x in the equation 6x-5/2 = 2x+6​

Answers

Answer:

x= 17/8

Step-by-step explanation:

6x− 5/2=2x+6

Step 1: Simplify both sides of the equation.

6x+−5/2=2x+6

Step 2: Subtract 2x from both sides.

6x+−5/2−2x=2x+6−2x

4x+−5/2=6

Step 3: Add 5/2 to both sides.

4x+−5/2+5/2=6+5/2

4x=17/2

Step 4: Divide both sides by 4.

4x/4=17/2/4

x=17/8

#SPJ2

Explain some methods of reducing friction between of matyer​

Answers

Answer:

Step-by-step explanation:

1. Use of lubricants

Lubricants like oil and grease helps to decrease friction by forming a thin film in between different parts of the machine. This film covers up the scratches and bumps on the surfaces of different parts. This reduces interlocking between the two surfaces.  Thus reducing the friction.

2. Use ball bearings

Two moving surfaces in a machine are attached by placing small steel balls or steel rollers  in between them. This way, the moving parts avoid direct contact and the force of sliding friction turns into rolling friction. Rolling friction is less than sliding friction, in doing so reducing the friction.

3. Polishing

Polishing reduces the unevenness  of a surface. This will reduce interlocking between the surfaces.  

4. Streamlining

Streamlining is the process where you make a machine in a shape that avoids air and water resistance. This reduces friction because a streamlined object cuts through the water and air molecules.

What is the value of the expression below?
14 divided by 2 + 3(4) - (6 1/2 - 3)

Answers

Answer:

15.5

Step-by-step explanation:

Original Equation:

14 ÷ 2 + 3(4) - (6.5 - 3)

Do the Parentheses first.

6.5 - 3 = 3.5

Equation:

14 ÷ 2 + 3(4) - 3.5

More Parentheses.

3(4) = 3 ⋅ 4 = 12

Equation:

14 ÷ 2 + 12 - 3.5

Divide.

14 ÷ 2 = 7

Equation:

7 + 12 - 3.5

Add.

7 + 12 = 19

Subtract:

19 - 3.5 = 15.5
