Answer: 5(x - 12) = 3x

Step-by-step explanation:

       We can cross-multiply to answer this question.

[tex]\frac{5}{x} =\frac{3}{x-12}[/tex]

5 * (x - 12) = 3 * x

5(x - 12) = 3x

Answer:

b) 5(x - 12) = 3x

Step-by-step explanation:

Given expression,

→ 5/x = 3/(x - 12)

Now we have to,

→ Find the equivalent expression.

Let's find the required answer,

→ 5/x = 3/(x - 12)

Cross multiplying both sides:

→ 5(x - 12) = 3(x)

→ 5(x - 12) = 3x

Applying Distributive property:

→ 5(x) - 5(12) = 3x

→ 5x - 60 = 3x

Solving for the value of x:

→ 5x - 3x = 60

→ 2x = 60

→ x = 60/2

→ [ x = 30 ]

Hence, the value of x is 30.

The size tray of plants which is the best value for money is large tray.

A small tray of 10 plants costs £2.50

Cost per unit = Total cost / number of plants

= £2.50 / 10 plants

= £0.25 per plant

A medium tray of 40 plants costs £8.40

Cost per unit = Total cost / number of plants

= £8.40 / 40 plants

= £0.21 per plant

A large tray of 90 plants costs £12.60

Cost per unit = Total cost / number of plants

= £12.60 / 90 plants

= £0.14 per plant

Hence, the large tray of 90 plants costs £12.60 is the best buy for your money.

Answer:

i'm pretty sure it is "the graph forms a parabola"

Step-by-step explanation:

The term (100 C 15) represents the number of ways to choose 15 defective screws out of 100 packs.

In a scenario where there are 2 defective screws out of 100 packs, each containing 500 screws, we can calculate the probability of obtaining 15 defective screws. Let's assume that each pack is independent of the others.

The probability of a single screw being defective is 2/500, as there are 2 defective screws out of 500 in each pack.

Conversely, the probability of a screw being non-defective is 498/500.

To find the probability of obtaining exactly 15 defective screws, we can use the binomial distribution formula. The probability (P) can be calculated as follows:

P = (100 C 15) * (2/500)^15 * (498/500)^85

The term (100 C 15) represents the number of ways to choose 15 defective screws out of 100 packs.

By plugging these values into the formula and performing the calculations, the probability of obtaining exactly 15 defective screws can be determined. However, I am unable to perform the calculation for you within the given word limit.

Using the secant-secant theorem, the possible values of x are x = 6 and x = -10. -10 cannot be a value of x because length cannot be negative.

From the question, we are to determine the value of x in the given diagram.

The Secant-secant theorem states that

"Given two secant segments which share an endpoint outside of the circle, the product of one secant segment and its external segment is equal to the product of the other segment and its external segment"

Thus,

We can write that

5 × (5 + 7) = x × (x + 4)

Simplifying

5 × 12 = x² + 4x

60 = x² + 4x

x² + 4x - 60 = 0

Solve the quadratic equation

x² + 4x - 60 = 0

x² + 10x - 6x - 60 = 0

x(x + 10) - 6(x + 10) = 0

(x - 6)(x + 10) = 0

x - 6 = 0 or x + 10 = 0

x = 6 or x = -10

Since x cannot be negative,

x = 6

Hence, the value of x is 6

Step-by-step explanation:

The average gas mileage of the cars traded is 15.8 miles per gallon round to the nearest.

Let's assume that the average gas mileage of the cars traded in is x miles per gallon. According to the problem, the average increase in gas mileage for the new car purchased versus the car traded in was 61%. This means that the new car gets 61% more miles per gallon than the car traded in. We can express this relationship mathematically as:

25.4 = x + 0.61x

Simplifying the right-hand side of the equation, we get:

25.4 = 1.61x15.78

Dividing both sides by 1.61, we get:

x = 15.78

Therefore, the average gas mileage of the cars traded in was approximately 15.8 miles per gallon, rounded to the nearest tenth.

To understand this result, we can interpret it as follows: for the first week of the "Cash for Clunkers" program, the average gas mileage of the new cars purchased was 25.4 miles per gallon, which is 61% higher than the average gas mileage of the cars traded in. This suggests that the program was successful in incentivizing people to trade in their old, less fuel-efficient cars for new, more fuel-efficient cars.

Answer: We can use both formulas to calculate the interest on an investment of $3500 at 2.75% for 3 years.

Using the formula A = P(1+r/n)^(nt), where A is the final amount, P is the principal amount, r is the annual interest rate as a decimal, n is the number of times interest is compounded per year, and t is the time in years, we have:

A = 3500(1+0.0275/1)^(1*3) ≈ $3843.84

Therefore, the interest earned is:

Interest = A - P = $3843.84 - $3500 = $343.84

Using the formula A = Pe^(rt), where A is the final amount, P is the principal amount, r is the annual interest rate as a decimal, t is the time in years, and e is the mathematical constant approximately equal to 2.71828, we have:

A = 3500e^(0.0275*3) ≈ $3843.84

Therefore, the interest earned is:

Interest = A - P = $3843.84 - $3500 = $343.84

The interest earned is $343.84 in both cases.

The solutions of the given equations are x = 0 and x = -36.

We have,

To solve these equations:

9x - 7 = -7

We can add 7 to both sides to isolate the variable:

9x - 7 + 7 = -7 + 7

Simplifying the left-hand side and the right-hand side, we get:

9x = 0

Finally, dividing both sides by 9, we get:

x = 0

Next, to solve:

-1 = 5 + x/6

We can begin by subtracting 5 from both sides:

-1 - 5 = 5 + x/6 - 5

Simplifying the left-hand side and the right-hand side, we get:

-6 = x/6

Finally, multiplying both sides by 6, we get:

The measure of value of ∠5 is 83°.

Now, It is given that;

Two Lines m and n are parallel with each other and l is the transversal crossing the two given parallel lines.

And, m∠6 = 97°,

Since, Two rays combined into an angle have a single terminal. The point is known as the vertex of the angle, while the rays are known as its sides, occasionally as its legs, and occasionally as its arms.

Hence, Then by using the property of liner pair angles, we have

⇒ m∠5 + m∠6=180°

(Because they form a linear pair angles.)

⇒ m∠5 + 97 = 180

Subtract 97 both side, we get;

⇒ m∠5 + 97 - 97 = 180 - 97

⇒m∠5 = 180 - 97

⇒m∠5 = 83°.

Therefore, the value of the measure of ∠5 is,

Step-by-step explanation:

The required derivative of f(x) = (3x² - 4x + 1)⁴ is f'(x) = 4(3x² - 4x + 1)³ * (6x - 4)

We can use the chain rule and power rule of differentiation to find the derivative of f(x).

Let u = 3x² - 4x + 1, then we have:

f(x) = u⁴

Using the chain rule, we get:

f'(x) = 4u³ * u'

To find u', we can differentiate u with respect to x using the power rule:

u' = d/dx (3x² - 4x + 1) = 6x - 4

Substituting u' and u into f'(x), we get:

f'(x) = 4(3x² - 4x + 1)³ * (6x - 4)

we can see that the function C(x) = 25x + 75 represents the labor cost (in dollars) for Bob's Auto Repair to replace your alternator, where x is the number of hours. We can use this function to find the cost of replacing an alternator that is estimated to take 5 hours of labor.

C(5) = 25(5) + 75 = 125 + 75 = 200

We also have the labor cost for the main competitor, Budget Auto Repair, in a table format.

Hours Cost

We can see that the cost of labor increases as the number of hours increases. From the information provided it's hard to say which company would be cheaper to hire, however the company with the function C(x) = 25x + 75 would be cheaper if the alternator takes more than 4 hours of labor, otherwise Budget Auto Repair would be cheaper.

It's important to check the warranty, prices of parts, and reputation of both companies. If a company has a good reputation and a good warranty, it may be worth paying a little more for labor.

It's also a good idea to get a second opinion or ask for a quote from both companies before making a decision.
