So to solve your question, we can use this: 

\sf{a(b-c) = ab-ac}
\sf{a(b+c) = ab+ac}

So then 

\sf{-(6w-1)}

If we use the above formulas then:
\sf{-(6w-1) = -6w+1}

And for
\sf{3(w-4)}

We will get:

\sf{3(w-4) = 3w-3(4) =3w-12}

And to simplify
\sf{-(6w-1)+3(w-4)}

Since we already calculated the individual parts, not put them together, so:

\sf{-6w+1+3w-12}

Now we have to add the like terms which are -6w and 3w. And also 1 and -12.

Rearranging the terms, we get:

\sf{-6w+3w-12+1}

And \sf{-12+1=-11}

And also \sf{-6w+3w= w(-6+3) = w(-3) = -3w}

So combining that, we get:

\sf{-3w-11}

Which is your final answer :)

Answer:

x= 3.57

Step-by-step explanation:

32 ( x + 2.5) = 114.24

32* x + 32* 2.5= 114.24

32x + 80= 114.24

        -80      -80

32x= 114.24

/ 32    /32

x= 3.57

pentagon [3]

Answer:

Mr. Terry has $36.60 left after these purchases.

Step-by-step explanation:

1. Multiply the amount of glue sticks purchased by their singular cost.

24 x 1.15= 27.6

2. Multiply the amount of pencil packs purchased by their singular cost.

10 x 0.58= 5.8

3. Add the solutions.

27.6+5.8=33.4

4. Subtract 33.4 from 70.

70-33.4=36.60
