Expand to write an equivalent expression -5(7m-2)

Mathematics

Elena-2011 [213]2 years ago
5 0
So lets use the distributive property on this problem:

First we multiply-
-5(7m)= -35m
Next we multiply-
-5(-2)=10
Its a positive 10 and not a negative because two negatives equal a positive.
And then we just put it together so our new expression would be
-35m+10

A hospital stores one type of medicine in 2-decagram
Aleks04 [339]

Answer:

There are 20,000 milligrams in one 2-decagram container . Thus option D is correct.

Step-by-step explanation:

The given information is one type of medicine in 2 decagram container.

Here, we know ,

                           =20,000 milligrams .

Hence, the correct option is D that is 20,000 milligrams .
