Answer:
x+4/x-4
Step-by-step explanation:
=x/(x-4)+4/(x-4) [ l.c.m= (x-4)]
=x+4/x-4
Answer:
X = 4
Step-by-step explanation:
-2 times any positive is a negative
X also can't be a negative
so -2 times 4 = -8

Answer:
Alex can line eight 1-meter wide with the paper.
Step-by-step explanation:
- Alex has five rolls of shelf paper that is 800cm.
- She wants to use the paper to line the 1-meter wide shelves in her pantry.
- We want to determine how many 1-meter wide she can line with the paper.
- First, we know that
100cm = 1m
- we need to determine how many meters are in 800cm.
100cm = 1m
800cm = xm
100x = 800
x = 800/100
= 8
Therefore, 800cm is equivalent to 8m
Alex can line eight 1-meter wide with the paper.
