Answer:

All expressions are correct

Step-by-step explanation:

9z+7z = 16 z

The base of an isosceles triangle is 4/5. The perimeter of the triangle is 4\2\15 what is the length of either of the remaining
crimeas [40]

Answer:

  1 2/3

Step-by-step explanation:

Assuming you mean the perimeter is 4 2/15, the sum of the lengths of the two equal sides is ...

  4 2/15 - 4/5 = 4 2/15 - 12/15 = 4 -10/15

Then either of the remaining sides is half this value, or ...

  (4 -10/15)/2 = (4/2) -(1/2)(10/15) = 2 -5/15 = 1 10/15 = 1 2/3

Each of the remaining sides has length 1 2/3.
