Answer 3

Okay so,

\[-25+\frac{ 4 }{ 9}b=-21\]

\[\frac{ -25+4 }{ 9b }=-21\]

B = \[\frac{ 1 }{ 9 }\]

Answer 4

For the second rewrite in simple terms,

It is −9q+11r

Answer 5

How I got it was,

\[−(−9q+3r)+6r−2(−4r+9q)\]

Next,

Remove parenthesis for addition or subtraction..
\[9q−3r+6r−2(−4r+9q)\]

Distributive property
\[9q−3r+6r−2(−4r)−2×9q\]

Determine sign for either multiplication or division..
\[9q−3r+6r+2×4r−2×9q\]

Multiply monomials
\[9q−3r+6r+8r−18q\]

Answer 6

9q-3r+6r+8r-18q. yep alexis is amazingly correct
