What is 6b-27=3(5b-2)

irga5000 [103]

Hi,

Start with 6b-27=3(5b-2)

then add 27 to each side, 6b-27+27=15b-6+27

next simplify, 6b=15b+21

now subtract 15b from both sides, 6b-15b=15b+21-15b

simplify again, -9b=21

divide both sides by -9, -9b/-9 = 21/-9

answer: -7/3

Have a great day!

Joanna went school supply shopping. She spent $32.49 on notebooks and pencils. Notebooks cost $2.41 each and pencils cost $1.46

Maslowich

Well, you need write the system of equation:

If we call "P" to quantity of pencils and we call "N" to quantity of notebooks, the total quantity of articles in an equation is:

P+N=19

And the total money that Joanna spent in an equation is:

$1.46*P+$2.41*N=$32.49

Now you only need to solve that system.
Good luck!
