Answer:
D. X= -100
Step-by-step explanation:
5×x/5=5×(-20) (reduce and multiply)
X= -100
The new model is 11/40 of an inch thinner than the old model.
In order to do this, we need to subtract the new model from the old model.

In order to complete this, we will need common denominators.
35/40 - 24/40
Then simply complete the operation.
11/40
