7:
5x12=60
8x14=112
60+112=172
8:
12X28=336
hope this helps :)
<span>9c+(8+3c)
9c+8+3c (collect like terms)
9c+3c+8
12c+8
12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:
12c+8 (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)
4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)
</span>
I f you divide 350 by 2 you get 175. Then take 175 and multiply it by 6 you get 1,050 liters.
90 - (90 × .7) = $27
hope this helps
