(x-1)/ (x+7). factor the top (x-1)(x-7). then factor the bottom. (x+7)(x-7) so it should read, (x-1)(x-7)/(x+7)(x-7) the 2 (x-7) cancels out. so your left with (x-1)/(x+7). I hope this helps
9-3 because triple equals to 3. Mike has been studying for 9 years, so 9-3 with no = sign.
It will be B easy!! ..):&:?:$:$,
For this case we can make the following rule of three:
1/10 scarf ------> 4/5 hour
x ------------------> 1 hour
Clearing the value of x we have:
x = (1 / (4/5)) * (1/10)
Rewriting we have:
x = (5/4) * (1/10)
x = 5/40
x = 1/8
Answer:
A fraction of a scarf that alison can knit in 1 hour is:
