The value of the x in a linear equation is 7.8.

According to the statement

We have to find that the value of x.

So, For this purpose, we know that the

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

From the given information:

A is between points B and C. AB = 2x - 3, BC = 7x - 10, and AC = 32.

It means

BC = BA + AC

Then we have to substitute the values in it

Then

BC = BA + AC

7x - 10 =  2x - 3 + 32

7x - 2x = -3 +32+10

5x = 39

here the values of the x is a

x = 39/5.

x = 7.8

The first step in simplifying the expression 2(x+3)+5 = 2x+2(3)+5.

Given expression in 'x' is 2(x+3)+5.

In order to simplify this expression, we need to expand it by opening the parenthesis. That is, we need to distribute 2 over (x+3) first. For this we multiply 2 into (x+3) and then only we can add 5 to it.

So, 2(x+3) +5 = 2x + 2(3) +5

                     = 2x +6 +5

The value of j is j = 103 - k = 115 - f.

A collection of equations for which we searched for common solutions is referred to in mathematics as a system of equations, sometimes known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized. In everyday life, systems of equations are used to model problems when the unknown values can be represented by variables.

Consider the two equations,

Subtracting k from each side of the equation.

j + k - k = 103 - k

j = 103 - k

The time taken by the water to reach 49 degree Celsius is 4 minutes.

According to the question, larger amount of sodium chloride is dissolved in the heating water. And the given data states that the water temperature increases 7 degree Celsius every minute.

Initial temperature of water is 21 degree Celsius.

Let us assume, water reaches at 49° C after 'm' minutes.

As per question, every minute temperature increases as 7°C. So, the expression can be written as: (21 + 7m)°C

⇒ 21 + 7m = 49

⇒m = 4 minutes.

Hence, the time taken to reach 49° C is 4 minutes.

All About the FICA Tax

If you earn a wage or a salary, you’re likely subject to Federal Insurance Contributions Act taxes. Not to be confused with the federal income tax, FICA taxes fund the Social Security and Medicare programs. Also known as payroll taxes, FICA taxes are automatically deducted from your paycheck. Your company sends the money, along with its match (an additional 7.65% of your pay), to the government. In this article we’ll discuss what FICA taxes are, how they’re applied and who’s responsible for paying them.

Planning your finances goes beyond just taxes. Find a local financial advisor today.

FICA Taxes: The Basics

Every payday, a portion of your check is withheld by your employer. That money goes to the government in the form of payroll taxes. There are several different types of payroll taxes, including unemployment taxes, income taxes and FICA taxes. Two types of taxes fall under the category of FICA taxes: Medicare taxes and Social Security taxes.

Paying FICA taxes is mandatory for most employees and employers under the Federal Insurance Contributions Act. The funds are used to pay for both Social Security and Medicare.

If you own a business, you’re responsible for paying Social Security and Medicare taxes, too. For self-employed workers, they’re referred to as SECA taxes (or self-employment taxes) based on regulations included in the Self-Employed Contributions Act.

A wage base limit applies to employees who pay Social Security taxes. This means that gross income above a certain threshold is exempt from this tax. The wage limit changes almost every year based on inflation. In 2021, it was $142,800. For 2022, the limit rose to $147,000. This income ceiling is also the maximum amount of money that’s considered when calculating the size of Social Security benefits.

Medicare taxes, on the other hand, don’t have a wage limit. But there’s an Additional Medicare Tax that high-income individuals must pay. That has been the case since January 1, 2013.

The Additional Medicare Tax rate is 0.90% and it applies to employees’ (and self-employed workers’) wages, salaries and tips. So any part of your income that exceeds a certain amount gets taxed for Medicare at a total rate of 2.35% (1.45% + 0.90%). That income ceiling for 2021 and 2022 is $200,000 for single filers, qualifying widows and anyone with the head of household filing status; $250,000 for married couples filing joint tax returns and $125,000 for couples filing separate tax returns. You can calculate how much you owe using Form 8959.

The resultant velocity is about 12.3 feet per second at a heading of 8.4°east of north, <1.8, 12.14>

In this question,

Amy is paddling her canoe across a lake at a speed of 10 feet per second headed due north.

The wind is blowing 40°C east of north with a velocity of 2.8 feet, per second.

We need to find Amy's resultant velocity.

We write the direction vector for Amy in component form.

Due north is equivalent to 90° from the horizontal.

x-component:

x = 10 cos(90°)

x = 0

And y-component:

y = 10 sin(90°)

y = 10

The component form for Amy’s vector is <0, 10>.

Now we write the direction vector for wind in component form.

40 east of north is equivalent to 50° from the horizontal.

x-component:

x = 2.8 cos(50°)

x = 1.8

And y-component:

y = 2.8 sin(50°)

y = 2.14

The component form for the wind’s vector is <1.8, 2.14>

Add the vectors for Amy and the wind.

<0, 10> + <1.8, 2.14> = <1.8, 12.14>

Now, we determine the vector's magnitude by using Pythagoras theorem.

Let v be the velocity of Amy.

Let θ be the angle made by Amy with the horizontal

⇒ tan(θ) = |y/x|

⇒ tan(θ) = |12.14 / 1.8|

⇒ θ = 81.6°

81.6° with the horizontal is equivalent to 8.4° east of north.

Therefore, the resultant velocity is about 12.3 feet per second at a heading of 8.4°east of north, <1.8, 12.14>

The solution of the equation 5x/4 - 3/x= 1/4 for x is (1+√241)/10 or (1 -√241)/10.

According to the given question.

We have an equation 5x/4 - 3/x= 1/4.

As we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.

Therefore, the solution of the equation 5x/4 - 3/x= 1/4 for x is given by

5x/4 - 3/x= 1/4

⇒ ( 5x^2 -12) /4x  = 1/4

⇒ 5x^2 - 12   = (1/4)4x                 (multiplying both the sides by 4x)

⇒ 5x^2 - 12 = x

⇒ 5x^2 - x -12 = 0

⇒ x = [tex]\frac{1\pm\sqrt{1+240} }{10}[/tex]

⇒ x = (1+√241)/10 or (1 -√241)/10

Hence, the solution of the equation 5x/4 - 3/x= 1/4 for x is (1+√241)/10 or (1 -√241)/10.
