Cx/a+f=b solve for x

Mathematics
1 answer:
serg [7]3 years ago
7 0

(cx/a) + f = b

isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract f from both sides

(xc/a) + f (-f) = b (-f)

xc/a = b - f

Next, multiply a to both sides

(xc/a)a = (b-f)a

Distribute a to all terms within the parenthesis

xc = ab - a(f)

Finally, to isolate the x, divide c to both sides

(xc)/c = (ab - a(f))/c

x = (ab - a(f))/c

x = (ab - a(f))/c is your answer

hope this helps

Talia earns 85 cents for cans she recycles.If she gets a nickel for each can,how many cans does she recycle?
Over [174]

Answer:

Step-by-step explanation

Hi there,

We know she gets 1 nickel for every can, and 1 nickel is just 5 cents. So we first get this set up:

\frac{1 \ Nickel}{can} =\frac{5 \ cents}{can}      Now, we also know she gets 85 cents for a certain amount of cans, x:

\frac{85 \ cents}{x \ can}     Now, we can just use the proportionality we designed above, but flip it so <em>cans</em> cancel out:

x \ cans = 85 cents * \frac{1 can}{5 cents} = 17 cans  

Thus, Talia recycles 17 cans.

Evgesh-ka [11]

Answer:

Expected number of matches that occur = 4 matches

Step-by-step explanation:

First of all, let X_i be the event that when we turn over card i if it matches the required cards face.

Thus, for example X_1 is the event that turning over one card results in an ace while X_2 is the event that turning over second card reveals a deuce.

The number of matched cards "N" is given by the sum of this indicator random variable as shown in the attached file;

Which of the fractions is in lowest terms and is equivalent to -1.25
hjlf

Answer:

  The lowest terms equivalent to - 1.25  =  - \frac{5}{4}

Step-by-step explanation:

- 1.25 = - 1\frac{25}{100}

         = - ( 1 × 100 +25) ÷ 100

         =  -( \frac{125}{100} ) × (\frac{5}{5}

        =  - \frac{25}{20}

        =  - (\frac{25}{20}) × (\frac{5}{5}

        =  - \frac{5}{4}
