Answer:

Step-by-step explanation:

More than anything else, Algebra is a procedure. It has rules and axioms which when followed produce answers to problems -- problems that may not yield anything without Algebra.

These axioms and rules are familiar to anyone who has taken a course in advanced Mathematics. So each person who knows the procedure knows also how mathematics can work. It is a universal language spoken by those trained in what it offers to the education of both the "sender" and the "receiver."

The total surface area of a cuboid is 112cm^2. find the value of x. values given: 10cm and 2cm.

Tatiana [17]

Answer:

x= 5.6

Step-by-step explanation:

we will need to put the information we currently have into an equation:

10•2•x= 112

then multiply 10•2 which equals 20...then the equation wil turn out like this:

20•x=112

now you will isolate the x... but how?? dividing 20 by itslef.. cancelling it out, and if you do one thing to the other side of the equation, you have to do it to the other...

20/20•x=112/20

you will end up with x= 122/20

you can use a calculator for this step, but to practice long division... (check the screen shot thingie)

hope this helped !! ^^

A washing machine sells for $201 after being discounted by 40 percent. What was the original price of the washing machine?

olga_2 [115]

Step-by-step explanation:

Let original price be x

Price after 40% discount is $201

Therefore

x × 40% = $201

x = 201 ÷ (40/100)

x = 502.5

Therefore, the original price is $502.5

Hope it helps :)

Dara ran on a treadmill that had a readout indicating the time remaining in her exercise session. When the readout indicated 24

malfutka [58]

Answer:

The correct option is E. 16 min 12 sec.

Step-by-step explanation:

Consider the provided information.

When the readout indicated 24 min 18 sec, she had completed 10% of her exercise session.

That means 24 min 18 sec is 90% of her exercise time.

First convert the 24 min 18 sec into seconds:

24 min 18 sec = 1440+18 = 1458 seconds

Let x represents the 100%.

$\frac{1458}{x}=\frac{90\%}{100\%}$

$x=\frac{1458}{0.9}$

$x=1620$

That means the total time of workout was 1620 seconds or 27 minutes.

Now she had completed 40% of her exercise session, that means the readout will indicate 60% of the time.

Calculate the 60% of 1620 as shown:

$1620\times \frac{60}{100}=972$

Now convert 972 seconds into minutes as shown:

972 seconds = 960 seconds + 12 seconds = 16 min 12 seconds

Hence, the correct option is E. 16 min 12 sec.
