At another school they sell a different brand of gift wrap which costs $2 per package and cards for $5 per package. Your friends
zhenek [66]
Hi there,

5x?=110 ?=22

how? 110/5=22

now 2x?=110

110/2=55    ?=55'

so we know now that people bought 22 packages with card and 55 w/th out cards!

so no we need to divide 695/both

695/5=139 packages with cards 

695/2=347 packages without cards 

SO

139 packages with card 

347 packages without card

If an airplane descends 15 feet every 1.45 seconds, how far would the airplane travel in three and a half minutes? The equation
NemiM [27]

\qquad\qquad\huge\underline{{\sf Answer}}

Here we go ~

The air plane descends 15 feels every 1.45 seconds, so it's unit rate is :

\qquad \sf  \dashrightarrow \:  \dfrac{15}{1.45} \:  \:  ft / sec

Now we have to calculate the descent in 3.5 minutes ~

\qquad \sf  \dashrightarrow \:  \dfrac{15}{1.45} \:  \:   \times 3.5 \times 60

\qquad \sf  \dashrightarrow \: 2172.41 \:  \: ft

So, the airplane descends 2172.41 feels in three and a half minutes ~
