I need help with this question!!!
Nuetrik [128]

Answer: B. positive 6

Step-by-step explanation: Addomg the positive number to a negative number would turn it to a positive eventually. So u covert your factions to decimals to better see the resemblance. And 1 1/2 is the same as 1.5, and 2 1/10 is the same as 2.1 but it’s easier to deal with decimals. So then just add the positive to the negative sense 1 1/2 is closer to zero. I hope this helps I’m not the best at explaining things

PLEASE HELP!
Orlov [11]
We have that
<span>If (5x-4+13x=5) -------------->  then x=1/2
Step 1
</span>let's substitute the value of x = (1/2) in the expression [5x-4+13x] and verify its result
5*(1/2)-4+13*(1/2)
(5/2)-4+(13/2)
(5-4*2+13)/2----------> (5-8+13)/2=10/2=5
then 
5=5-----------> <span>the value of x = (1/2) satisfies equality</span>

I need help on a math problem<br> 48w^3+128w^2+4w-1<br> divided by<br> 4w
raketka [301]
Divide 4w to every term separately.

\sf\dfrac{48w^3+128w^2+4w-1}{4w}

\sf\dfrac{48w^3}{4w}+\dfrac{128w^2}{4w}+\dfrac{4w}{4w}-\dfrac{1}{4w}

48/4 = 12
w^3/w = w^2
So our first term is 12w^2.

128/4 = 32
w^2/w = w
So our second term is 32w.

4w/4w = 1
Anything divided by itself is 1.

-1/4w, this can't be simplified further, so this is our last term.

So we have:

\sf 12w^2+32w+1-\dfrac{1}{4w}
