" -20 + 5p - 7z " is not a question, and it doesn't beg for an answer.
It's an expression that stands for a number.
In order to determine what the number is, you need to know the
values of 'p' and 'z'. And if either of those changes, then the value
of " -20 + 5p - 7z " immediately changes too. So the whole thing is
a 'moving target'.
Answer:
It’s A
Step-by-step explanation:
You haven't provided expressions, so I can work out the problem for you. When we divide fractions, remember always "keep, switch, flip!" That's what we're gonna do here. We keep the 2/5, switch the sign to multiplication, and flip the 7/8 to 8/7. Therefore, we have 2/5*8/7. That gives us 16/35. Hope this helps!
