P = a + b - 4

subtract b from both sides

P - b = a - 4

add 4 to both sides

P - b + 4 = a

To solve for 'a' in the equation P = a + b - 4, you should subtract 'b' from both sides and add 4 to both sides to get a = P - b + 4.

The question asks to solve for a in the equation P = a + b - 4. To do this, we need to isolate a on one side of the equation. Thus, we start by subtracting b from both sides and then adding 4 to both sides. The resulting equation will be a = P - b + 4. This procedure is quite different than solving quadratic equations like ax² + bx + c = 0, where we have to use the quadratic formula -b ± √b² - 4ac / 2a to find the solutions.

Answer:  A

Step-by-step explanation:

Let us first observe behavior in only quadrant 1 .

On x-axis one small box represent one year.

On y-axis one small box represent  one dollar.

If we see the 1 year on x-axis its corresponding value of dollar on y -axis is in mid of 4 dollars and 5 dollars.

Now if we see the 2nd year on x-axis its corresponding value of dollar on y-axis is at 6 dollars .

It concluded that after each year 0.5 dollars per pound increases.

We can see the same behavior throughout the straight line.

C. 4:5=32:40 is your answer

Treat each ratio like fractions. Note the equal sign. This means that, when each fraction is simplified, they would be the same.

4/5 = 4/5

(32/40)/(8/8) = 4/5

4/5 = 4/5

∴ (C) is your answer

Step-by-step explanation:

The ratio of emails sent to emails received by Nick that month is 5:3 in its simplest form, determined by calculating their greatest common divisor.

The subject of your question is ratios and it falls under the category of Mathematics.

'For every 50 emails that Nick sent in a month, he received 30 emails.' This tells us about a ratio. A ratio is a way to compare amounts of something.

The ratio in this case is the number of emails sent by Nick to the number of emails he received. We express this ratio as '50:30'.

To simplify the ratio, we find the greatest common divisor (GCD) of 50 and 30, which is 10. So, we divide both numbers by 10. Thus, our simplified ratio is 5:3.

This means Nick sent 5 emails for every 3 emails he received, in simplest terms.

f(3) = 2x² - 3x + 1

2(3)² - 3(3) + 1

18 - 9 + 1

F(3) = 10

f(2) = 2(2)² - 3(2) + 1

8 - 6 + 1

f(2) = 3

f(3) - f(2)

10 - 3

f(3) - f(2) = 7 because you find f(3) = 10, and f(2) = 3, and plug in the answer you found. This gives you 10 - 3, which is 7.

The value of f(3) - f(2) is 7 if the function f(x) = 2x² - 3x + 1 the correct answer is option B: 7.

To find f(3) and f(2), we need to plug the respective values of x into the given function f(x) = 2x² - 3x + 1 and then subtract the results.

f(3):

f(3) = 2(3)² - 3(3) + 1

f(3) = 2(9) - 9 + 1

f(3) = 18 - 9 + 1

f(3) = 10

f(2):

f(2) = 2(2)² - 3(2) + 1

f(2) = 2(4) - 6 + 1

f(2) = 8 - 6 + 1

f(2) = 3

Now, let's find f(3) - f(2):

f(3) - f(2) = 10 - 3 = 7

So, the value of f(3) - f(2) is 7.

The correct answer is option B: 7.

The speed of the slower jets and faster jets are 624 mi / Hr and 684 mi/hr respectively.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.

Let the speed of a slower jet be represented as 'x'

Now Given:

one jet travels 60 mph slower than the other.

Hence Speed of a faster jet will be = x  +   60

Distance = 7848  miles

Time = 6 hrs

Now we know that;

Distance is equal to the product of speed and time.

Framing in the equation we get;

Distance = (Speed of Faster Jet + Speed of Slower jet) × Time.

Substituting the given values we get;

7848  =  ( x  +  x  +  60  )  6

7848  =  12x  +  360

x  =  624

Speed of slower jet = 624 miles/hr

Speed of faster jet = 624  +  60  =  684 miles/hr

Hence Speed of the Faster jet is 684 miles/hr and the speed of the slower jet is 624 miles/hr.

Answer: The amoun of the initial value was $1,289.

Step-by-step explanation:

1. To solve this problem you must apply the formula shown below:

[tex]A=Pe^{rt}[/tex]

Where:

- [tex]A[/tex] is the account balance ([tex]A=1,912.41[/tex]).

- [tex]P[/tex] is the principal.

- [tex]r[/tex] is the annual interest ([tex]r=0.0263[/tex]).

- [tex]t[/tex] is the time in years ([tex]t=15[/tex]).

- [tex]e[/tex]=2.7182

2. You must substitute the values into the formula and then you must solve for [tex]P[/tex], as following:

[tex]1,912.41=Pe^{(0.0263)(15)}\\1,912.41=1.48P\\P=\frac{1,912.41}{1.48}\\P=1,289[/tex]

Answer,

Explanation,

Step 1: Simplify both sides of the equation

24 − 3x = −27

24 + −3x = −27

−3x + 24 = −27

Step 2: Subtract 24 from both sides.

−3x + 24 − 24 = −27 − 24

−3x = −51

Step 3: Divide both sides by -3.

-3x/-3 = -51/-3

Answer:

There are 14 cows and 68 Chicken in the farm.

Step-by-step explanation:

A Cow has 4 legs

Chicken has 2 legs.

Lets take there [tex]x[/tex] chickens AND,

there are [tex]y[/tex] number of Cows.

Now we can write two equations for the number of heads and legs.

For the number of heads we can write,

[tex]x+y=82[/tex] <--------- 1st equation

For the number of legs we can write,

[tex]2x+4y=192[/tex] <------ 2nd equation

We can now solve the simultaneous equations to find [tex]x[/tex] and [tex]y[/tex]

Multiply 1st equation by 2 and deduct it from 2nd equation to remove [tex]x[/tex]

⇒[tex]2x+4y-2*(x+y)=192-164[/tex]

⇒[tex]2x+4y-2x-2y)=112-164[/tex]

⇒[tex]2y=28[/tex]

⇒[tex]y=14[/tex]

Therefore, there are 14 cows in the farm.

Now we can substitute the [tex]y[/tex] value to the 1st equation and find [tex]x[/tex] value.

[tex]x+14=82[/tex]

[tex]x=68[/tex]

Therefore, there are 68 chickens in the farm.

You have to see if they are all moving up at a constant rate. You can check this by subtracting $17.40 from $21.75. It is $4.35. Then multiply $4.35 by 46. If it is not equal to $200.10, then it is not a proportional relationship. When you multiply it, you actually do get $200.1, which is equal to $200.10. So this is a proportional relationship.

The base is from 2 to 7, which is 5 units long.

The question presents a basic algebraic problem. We translate the words into a mathematical equation, 4x + 7 = 5. After some simple manipulations (subtracting 7 from both sides and dividing the result by 4), we find that the value of x is -0.5.

The question presents a typical example of a simple equation in Mathematics. The first step in solving this problem involves interpretation. The statement 'The sum of 4 times a number and 7 is equal to 5' can be translated into this equation: 4x + 7 = 5. To obtain the value of x, we need to isolate it on one side of the equation.

We can proceed by subtracting 7 from both sides
to achieve 4x = -2. Finally, we divide both sides of the equation by 4 to obtain x = -0.5. Thus, the number in question is -0.5.

Let x be the number of rows.

If the number of rows is 7 less than the number of seats in each row, then the number of seats in a row is x+7. The total number of seats is

x·(x+7).

You know that a theater can seat 120 people, then

x·(x+7)=120.

Solve it:

[tex]x^2+7x-120=0,\\\\D=7^2-4\cdot (-120)=49+480=529,\ \sqrt{D}=23,\\\\x_1=\dfrac{-7+23}{2}=8, \ x_2=\dfrac{-7-23}{2}=-15.[/tex]

The number of rows must be positive, then x=8.

Answer: there are 8 rows with 15 seats at each.

95° because 85 + x = 180 so you do 180 - 85 and get 95
