Question

Drag each expression to show whether it is equivalent to

-1.3x - (-8.9x), -1.3 + (-8.9X) or nethier

−1.3x−8.9x

8.9x+(−1.3x)

−8.9x+(−1.3x)

8.9x−(−1.3x)

−1.3x+8.9x

−8.9x+1.3x


3 Boxes showing witch one is going.

−1.3x−(−8.9x)

−1.3x+(−8.9x)

Neither

Answer 1

Take a look yourself

Explanation:

Equivalent expressions are expressions which are equal. This means they simplify to the same expression. Simplify the two expressions -1.3x - (-8.9x) = 7.6x and -1.3 + (-8.9X) = -10.2x.

Then simplify each option to determine if it is equal -1.3x - (-8.9x), -1.3 + (-8.9X) or neither:

−1.3x−8.9x = -10.2x. This is equivalent to -1.3 + (-8.9X) .

8.9x+(−1.3x) = 7.6x This is equivalent to -1.3x - (-8.9x) .

−8.9x+(−1.3x) = -10.2x This is equivalent to -1.3 + (-8.9X) .

8.9x−(−1.3x) = 10.2x Neither

−1.3x+8.9x = 7.6x This is equivalent to -1.3x - (-8.9x) .

−8.9x+1.3x = -7.6x Neither

See below.

8.9x+(−1.3x) = 7.6x This is equivalent to -1.3x - (-8.9x) .

−8.9x+(−1.3x) = -10.2x This is equivalent to -1.3 + (-8.9X) .

8.9x−(−1.3x) = 10.2x Neither

−1.3x+8.9x = 7.6x This is equivalent to -1.3x - (-8.9x) .

−8.9x+1.3x = -7.6x Neither
