How to solve word problems?

It's actually fairly easy to solve word problems using a tried-and-true step-by-step approach. Aloud to yourself, read the issue.

Let the two numbers be x and y

One number is six less than a second number: x = y - 6 ⇒ i

Four times the first is 2 more than 6 times the second: 4x = 6y + 2 ⇒ ii

Substitute the value of x in (ii)

4(y-6) = 6y + 2

4y - 24 = 6y + 2

2y = -26

y = -13

Now substitute the value of y in (i);

x = -13 - 6

x = -19

Hence, the numbers are -19 and -13 by the given conditions.

The substance will weigh 9 pounds after  4.5123 hours.

Here it is given that every 3 hours the weight of the substance doubles.

At 12 noon it weighed 2 pounds. Hence we will consider the initial weight to be 2.

Let the weight after x hours be w(x)

Here it doubles in 3 hours, hence the growth rate is 100%

Since the growth rate is given, the equation for the growth rate will be

w(x) = w₀.eˣ

where x = no. of 3-hour spans.

Here

w₀ = 2

and w(x) is given 9

Hence,

2eˣ = 9

or, e²ˣ = 9/2

Taking log on both sides we get

loge²ˣ = ln(9/2)

or, 2xloge = ln(9/2)

Since loge = 1 we get

2x = log(9/2)

or, x = 1.5041

Hence they will become 9 pounds after

3 X 1.5041 hours

= 4.5123 hours

The triangles are similar triangles. Then the value of the variable 'x' will be 6.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

Similar triangles are shown below.

We know that the ratio of the corresponding sides of similar triangles remains constant. Then the equation is given as,

(6x - 1) / 15 = 14 / 6

Simplify the equation, then we have

Answer:  The percent that the house's value is going up each year is given by the factor 1.04 - 1, which is 0.04. This represents a 4% increase in the value of the house each year.

ii) To find the value of the home in 15 years, you can substitute x = 15 into the equation to get:

A = 400,000 (1.04)^15

= 400,000 (1.7589)

= 700,356

Therefore, the value of the home in 15 years is $700,356.

iii) To find when the value of the home will double, you can set the value of A equal to 2*400,000 and solve for x:

2*400,000 = 400,000 (1.04)^x

2 = (1.04)^x

x = log(2)/log(1.04)

= 10.67

Therefore, it will take approximately 10.67 years for the value of the home to double, assuming the trend continues.

The required number of employees does it have in total is 68877.

A percentage is a part of an entire communicated as a number somewhere in the range of 0 and 100 as opposed to as a small portion. Something is all 100%, a big part of it is 50%, none of something is zero percent. To decide a rate, you partition the piece of the entire by the actual entire and duplicate by 100.

Let total population of the company be X

So,

19.6% of x = 13500

x(19.6/100) = 13500

X = 13500×100/19.6 = 68877 employees

We have given that,

n = 25

mean of x = 49.98 mm

For an average intake of 2200 calories per day, the number of acres of land is approximately 2.

If we are given all a function so in that case, we just need to substitute values given in question and solve for unknown variable that is to be determined.

C(x) is a variable that tells the number of calories consumed daily by a person

x is the number of acres that person own.

C(x) = 270㏑(x+1) +1900

In the given question number of acres ask a person to have who consumed 2200 calories in a day.

Therefore,

C(x)=2200

2200=270㏑(x+1) +1900

2200-1900=270㏑(x+1)

300=270㏑(x+1)

300/270 = ㏑(x+1)

10/9 = ㏑ (x+1)

x+1 = [tex]e^{\frac{10}{9} }[/tex]

x+1 = 3.037

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

A + B + C = 119

Country B won 9 more than Country C so:

B = C + 9

Also, Country A won 39 more than the other two combined so:

A = B + C + 39

  = (C + 9) + C + 39

  = 2C + 48

Now we substitute into the equation:

A + B + C = 129

(2C + 48) + (C + 9) + C = 129

4C + 57 = 129

4C = 72

C = 18
