# What is the value of x if 10x + 3b = 12b + 7x.

## Answers

[tex]x-317=10x-137\qquad\text{add 137 to both sides}\\\\x=10x\qquad\text{subtract x from both sides}\\\\0=9x\qquad\text{divide both sides by 9}\\\\0=x\to\boxed{x=0}[/tex]

The value of x is 4. So 40000 mg= 40 g.

Step-by-step explanation:

The given is 40000mg = 10x g

Step:1

Take given equation as equation (1)

40000 mg= 10x g.................(1)

where, X is known value.

Step:2

Standard value for mg to g for the purpose of conversion of units,

1 milligram = 0.001 gram (or)

1 gram = 1000 milligram

Step:3

From the standard data values,

= 40000 mg

it converted mg to g by dividing 1000

= [tex]\frac{40000}{1000}[/tex] g

= 40 g.......................(2)

Step:4

From the Equations (1) and (2),

40=10x

x=4

Result:

The value of x is 4. So, 40000mg = 40 g.

Divide each term in the equation by 10.

10x/10=100000/10

Simplify.

x=10000

x is equal to 10000

Simply divide 100,000 by 10.

x = 10000

The answer is 35

choice A

The answer is the first one.

You do -5 to doth side and get:

10x>20

And then you divide both sides by 10 and get:

X>2

b=1/3x

Step-by-step explanation: hope this helps plz mark as brainliest:)
