Tammy's recipe makes a sweeter fruit punch. This is because 3/4 (Kim's recipe) equals 18/24 (Tammy's recipe) and 5/6 equals 20/24 and since 20/24 is the bigger ratio, Tammy's recipe will make a sweeter fruit punch. I hope this helps. (:
Answer: −8x−9
Step By Step:
Distribute the Negative Sign:
=−7x−14+−1(x−5)
=−7x+−14+−1x+(−1)(−5)
=−7x+−14+−x+5
Combine Like Terms:
=−7x+−14+−x+5
=(−7x+−x)+(−14+5)
=−8x+−9
Answer:
= −8x−9
The problem asks:
what is 2y+7 when y=-3?
Since y=-3 then 2y+7=2(-3)+7=-6+7=1.
Similarly, when y=-3, -4y − 10=<span>-4(-3) − 10=12-10=2.
Answer:
</span><span>2y + 7=1
-4y − 10=2</span>
[1] Amount of water per minute
Water Miser: m = 3.0 gal/min
Watersaver: m = 2.5 gal/min
Waterstream: m = 1.5 gal/min
[2] Equations:
I would suggest using y = mx.
Water Miser: y = 3x
Watersaver: y = 2.5x
Waterstream: y = 1.5x
[3] For 6,8,10, and 12 minutes:
Plug in x = 6, x = 8, x = 10, and x = 12 into each of the three equations and record the y-values.
[4] Which would you buy?
Depends on your personal opinion.
Want to save the earth? Pick the one that uses the least amount of water.
Want to have a waterfall for a shower? Pick the one that uses the most amount of water. :)
