The expression x-y equals 0.7 if x and y have certain values. Evaluate the following expression with the same values of x and y
elena55 [62]

Answer:

1/0.7

Step-by-step explanation:

The expression x-y equals to 0.7 so we have to substitute 0.7 in the place of x-y....

----> 1/0.7

Dividing would make this equal to a long division answer (1.42857142857) so let's just leave it as a fraction!

I hope this helps! :)
