3/5 - 1/7

Find the LCM of 5 and 7 to find equivalent fractions for both fractions

LCM = 35

3/5 = 21/35

1/7 = 5/35

So 21/35 - 5/35 = 16/35

I'm pretty sure that's the simplest form because I can't think of a common factor of 16 and 35 by which to reduce it further.

Kelly was building a bed for her dollhouse. She used her bed, which is 4 feet × 6 feet, as a guide. She scaled down the dimensio

Hey!
So when there is a scale factor you would always multiply it with the original dimensions, even if it wasn't a fraction.
so 4 time 1/5 is 0.8
and 6 times 1/5 is 1.2
so the dimensions of the model bed is 0.8 foot by 1.2 feet
Your answer is A!
Hope this helps!

Answer:

Answer is -6

Step-by-step explanation:

$given \: q(x) = 2x - 1 \\ and \: r(x) = - 2x \\ r(q(2)) = r(2(2) - 1) \\ \: \: = r(4 - 1) \\ = r(3) \\ = - 2(3) \\ = - 6 \\ therefore \: r(q(2)) = - 6$
