Answer:

y = -15

Step-by-step explanation:

y -3(y+5)=15    (distribute -3 into the parentheses)

y + y(-3)+5(-3)=15

y-3y-15=15

-2y -15 = 15  (add 15 to both sides)

-2y = 15 + 15

-2y = 30   (divide both sides by -2)

y = 30 / -2 = -15

What's the value of x? 40000mg =10x g
dybincka [34]

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

                    = \frac{40000}{1000} 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.
