Korvikt [17]

Answer:

Because a bracket is used, the solution includes 6.5

The solution includes numbers from negative infinity to 6.5

M×10+m×13=138<br><br>sorry theres another loll I'm so bad at these
Dimas [21]
So first of all you would add the two together
so it would be m23.

138÷23 would equal 6,

therefore m would equal six

to check it substitute m for 6 and you should get 138!

Which expressions are equivalent to ? Check all that apply.
GrogVix [38]

Answer:

6.2+8.7+8.9x

Step-by-step explanation:

For expressions to be equivalent, they must simplify to the same lowest form. 8.9x+6.2+8.7 simplifies to 8.9x +14.9.

Each of the expressions below must simplify to 8.9x + 14.9 to be equivalent.

9x+6+9  = 9x + 15 NO

3.9+6.2+8.7x  = 8.7x + 10.1 NO

3.7+8.9+6.2  = 18.8 NO

6.2+8.7+8.9  = 23.8 NO

6.2+8.7+8.9x  = 8.9x + 14.9 YES

3.9+6.2x+8.7  = 6.2x + 12.6 NO

3.9x+8.7+6.2 = 3.9x + 14.9 NO
