Directly proportional to x.

<h3>What is propotionality?</h3>

In algebra, proportionality is the equality of two ratios.
A and B are in the same ratio as C and D in the formula a/b = c/d.
When one of a proportion's four quantities is unknown, a proportion is often built up to resolve the word problem.
By multiplying one numerator by the opposing denominator and equating the result to that of the other numerator and denominator, the equation can be solved.
Any relationship that has a constant ratio is said to be proportionate. For instance, the ratio of proportionality is the average number of apples per tree, and the amount of apples in a crop is proportional to the number of trees in the orchard.

Acc to our question-

If two variables' ratios (yx)
(x and y) have the same value as a constant (k=yx)
therefore the ratio's variable (y) in the numerator is the sum of the other variable and the constant (y=k:x).
With a proportionality constant of k, it is claimed that y is directly proportional to x in this instance.

Hence,Directly proportional to x.

Andrew [12]

Answer:

Any number for x will work

Step-by-step explanation:

6x-3=3(2x-1)

expand

6x-3=6x-3

add three to both sides

6x=6x

simplify

x=x

Therefore any number for x will work

17. The radius of a circular path is 7m. Find the cost of fencing the path if the cost per meter is Rs.35

Elis [28]

The cost of fencing the path is Rs 1539.38.

It is required to find the cost of fencing the path.

<h3>What is circle?</h3>

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

Given that:

radius of a circular path is 7m.

Rate = Rs .35 per meter

We know that

Circumference of circle = $2\pi r$

$2*\pi *7\\\\=43.98 m$

Circumference of circle=43.98 m

Now,

Cost = Circumference × Rate

Cost =43.98× 35

Cost = Rs 1539.38

Therefore, the cost of fencing the path is Rs 1539.38.

Pls help me with this question.

umka21 [38]

Answer: C

Step-by-step explanation:

The equation is in y=mx+b format. The y is the final amount that you will have to pay. The m in this case is the amount of money that you are paying for each individual month (which is $34.99). The x in this case is the number of months you are paying for (which is 1). And b is the starting fee that you have to pay in order to get a membership in the first place (but will not have to pay after the first month). Thus, seeing as there is 1 month's worth of payment and a starting fee tagged on, y would equal the average total cost for the first month of a gym membership.
