Set up the equation. 5/17+3/8+3/10

The next step is to find an LCD.

After that, change all fraction's denominators to the LCD. Afterwards, add the numerators. I hope this helps!

what is the equation of the line in point slope form that goes through (-2,-1) and is perpendicular to y=5x+3?

stich3 [128]

Point slope form is $y-y1=m(x-x1)$

Since we have to write the equation of a perpendicular line we will have to use the slope that is opposite and reciprocal.

$y - (-1) = - \frac{1}{5} (x - (-2))$
$y + 1 = - \frac{1}{5} (x + 2)$

Hope this helps :)

On Tuesday kali by five CDs on Wednesday Half of all the CDs that she had were destroyed on Thursday there were 22 left how many

pshichka [43]

Answer:

Work:

(x+5)/2=22

We will reverse this equation.

We will start by moving the 2 through inverse operations.

22x2=44

Now we have the equation

x+5=44

We will subtract 5

44-5=39

x=39

the unknown variable equals 39

Kali had 39 CDs on Monday
