You are creating a model of a bookcase for a dollhouse.
Goshia [24]

Answer:

If the model is 3 inches tall, the model bookcase should be <em>2 inches</em> wide.

Step-by-step explanation:

When using similar figures, set up a proportion of the model measurements to the actual measurements:

\frac{3}{48}=\frac{x}{32}

Then cross multiply and solve for x:

48x=96\\x=\frac{96}{48}\\x=2

If this helped, a brainliest would be greatly appreciated!

Ok so
since we h ave
3.5=1 day's morning
and
2.3=1 day's afternoon
we need to add them to find 1 day and multiply by 6 (number of days)
that answer is not listted so we make into anohter form
this wold be

if we distributed
a(b+c)=ab+ac
6(3.5+2.3)=6 times 3.5+6 times 2.3

this is D
