Answer:

x = -20  

Step-by-step explanation:

-⅗(15x - 30) = 198

Multiply each side by 5

-3(15x - 30) = 990

Distribute the -3

-45x + 90 = 990

Subtract 90 from each side

-45x = 900

Divide each side by -45

x = -20

<em>Check: </em>

-⅗[15(-20) - 30] = 198

  -⅗(-300 - 30) = 198

          -⅗(-330) = 198

                 198 = 198

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
