Answer: 9 m + 7 n - 6 mn + 4 m
Step-by-step explanation:
m + 3 n + 6 mn - 4 .... for this expression , it is already in its simplified form as we can not add any term together because they are not have the same variables.
9 m + 7 n - 6 mn + 4 ..... this also is already simplified
7 m - 9 n - 6 mn + 4 ..... the same thing with this
9 m + 7 n - 6 mn + 4 m .... this particular can still be further simplified because we have 9m and 4m having the same variable and we can therefore add them together , the simplified form of the expression will be
13m + 7n - 6mn
Its increasing 40 miles for every hour
Answer:
10 and 10
Step-by-step explanation:
So for the first one, 1-(-9), the two subtraction signs cancel each other out and are turned into an addition symbol. The new equation would now be the absolute value of 1 + 9. As we know, 1 + 9 is 10, and the absolute value of 10 is 10. <u>The absolute value just means how many spaces the number is away from 0, and it will always be positive.</u>
<u></u>
For the second one, -9 -1 would equal -10. Even though -10 is negative, the absolute value will always be positive, so<u> the absolute value of the second one is also 10.</u>
<u></u>

Answer:
The mass of Sun is
times greater than mass of Mercury.
Step-by-step explanation:
We are given that
Mass of the sun=
kg
Mass of Mercury,
kg
We have to find how many times greater is the mass of the sun than the mass of Mercury.
Mass of sun/Mass of mercury=
Mass of sun/Mass of mercury
Using the property

Mass of sun/Mass of mercury
Mass of sun/Mass of mercury
Mass of Sun=
times Mass of Mercury
Hence, the mass of Sun is
times greater than mass of Mercury.
