Answer:
c=(f-d)/ab

Explanation:
abc+d=f
Move d to the other side
abc=f-d
Divide both sides by ab to cancel it out on the left side and isolate the c
abc/ab=(f-d)/ab
c=(f-d)/ab

I hope this helps! If it does, a brainliest would be much appreciated :)

Answer:

$P(38.6$

And we can assume a normal distribution and then we can solve the problem with the z score formula given by:

$z=\frac{X -\mu}{\sigma}$

And replacing we got:

$z=\frac{38.6- 45}{16}= -0.4$

$z=\frac{57.8- 45}{16}= 0.8$

We can find the probability of interest using the normal standard table and with the following difference:

$P(-0.4$

Step-by-step explanation:

Let X the random variable who represent the expense and we assume the following parameters:

$\mu = 45, \sigma 16$

And for this case we want to find the percent of his expense between 38.6 and 57.8 so we want this probability:

$P(38.6$

And we can assume a normal distribution and then we can solve the problem with the z score formula given by:

$z=\frac{X -\mu}{\sigma}$

And replacing we got:

$z=\frac{38.6- 45}{16}= -0.4$

$z=\frac{57.8- 45}{16}= 0.8$

We can find the probability of interest using the normal standard table and with the following difference:

$P(-0.4$

(4x - 3) + (3x+9)<br> Solve this!

dusya [7]

The answer for this problem would be 7x+6

Let's solve this problem step-by-step.

4x−3+3x+9

=4x+−3+3x+9

Step 1: Combine Like Terms.

=4x+−3+3x+9

=(4x+3x)+(−3+9)

So, the answer for this problem would be 7x+6.

scoray [572]

Answer:

$d = |- 5- 9|$

Step-by-step explanation:

Given

$Initial = 9^\circ F$

$Final = -5^\circ F$

Required

Determine the difference

Represent this with d.

d is calculated using

$d = |Final - Initial|$

The equation becomes

$d = |- 5- 9|$

OLga [1]

Answer:

522.60, hope that helps! (UwU)=/

Step-by-step explanation:

pencils: $4.10 * 6 ===> $24.60

pens: $6.50 * 12 ===> $78

notebook paper: $105 * 4 ===> $420

pencils + pens + notebook paper = total cost

24.60 + 78 + 420 = 522.60
