First you have to find the improper fraction then multiplied by the reciprocal so that would be 26/5×6/13

5 1/5 divided by 2 1/6
first make them into improper fractions
so 26/5 divided by 13/6
remember with division of fractions  "Keep,Change,Flip"
keep the 26/5, change the division into multiplication, and flip the 13/6 to 6/13
the solve
so 26/5 * 6/13
that equals 12/5 
or 2 2/5
or 2.4

Hope this helps :)

For integers a, b, and c, consider the linear Diophantine equation ax C by D c: Suppose integers x0 and y0 satisfy the equation;
Dmitrij [34]

Answer:

a.

x = x_1+r(\frac{b}{gcd(a, b)} )\\y=y_1-r(\frac{a}{gcd(a, b)} )

b. x = -8 and y = 4

Step-by-step explanation:

This question is incomplete. I will type the complete question below before giving my solution.

For integers a, b, c, consider the linear Diophantine equation

ax+by=c

Suppose integers x0 and yo satisfy the equation; that is,

ax_0+by_0 = c

what other values

x = x_0+h and y=y_0+k

also satisfy ax + by = c? Formulate a conjecture that answers this question.

Devise some numerical examples to ground your exploration. For example, 6(-3) + 15*2 = 12.

Can you find other integers x and y such that 6x + 15y = 12?

How many other pairs of integers x and y can you find ?

Can you find infinitely many other solutions?

From the Extended Euclidean Algorithm, given any integers a and b, integers s and t can be found such that

as+bt=gcd(a,b)

the numbers s and t are not unique, but you only need one pair. Once s and t are found, since we are assuming that gcd(a,b) divides c, there exists an integer k such that gcd(a,b)k = c.

Multiplying as + bt = gcd(a,b) through by k you get

a(sk) + b(tk) = gcd(a,b)k = c

So this gives one solution, with x = sk and y = tk.

Now assuming that ax1 + by1 = c is a solution, and ax + by = c is some other solution. Taking the difference between the two, we get

a(x_1-x) + b(y_1-y)=0

Therefore,

a(x_1-x) = b(y-y_1)

This means that a divides b(y−y1), and therefore a/gcd(a,b) divides y−y1. Hence,

y = y_1+r(\frac{a}{gcd(a, b)})  for some integer r. Substituting into the equation

a(x_1-x)=rb(\frac{a}{gcd(a, b)} )\\gcd(a, b)*a(x_1-x)=rba

or

x = x_1-r(\frac{b}{gcd(a, b)} )

Thus if ax1 + by1 = c is any solution, then all solutions are of the form

x = x_1+r(\frac{b}{gcd(a, b)} )\\y=y_1-r(\frac{a}{gcd(a, b)} )

In order to find all integer solutions to 6x + 15y = 12

we first use the Euclidean algorithm to find gcd(15,6); the parenthetical equation is how we will use this equality after we complete the computation.

15 = 6*2+3\\6=3*2+0

Therefore gcd(6,15) = 3. Since 3|12, the equation has integral solutions.

We then find a way of representing 3 as a linear combination of 6 and 15, using the Euclidean algorithm computation and the equalities, we have,

3 = 15-6*2

Because 4 multiplies 3 to give 12, we multiply by 4

12 = 15*4-6*8

So one solution is

x=-8 & y = 4

All other solutions will have the form

x=-8+\frac{15r}{3} = -8+5r\\y=4-\frac{6r}{3} =4-2r

where r ∈ Ζ

Hence by putting r values, we get many (x, y)

You need 3 1/2 cups of flour for each batch of cupcakes. How many whole batches can make if you have 17 cups of flour? Show two
rosijanka [135]

<u>ANSWER:</u>

4 batches of cupcakes can be made.

<u>SOLUTION: </u>

Given, we need 3\frac{1}{2} cups of flour for each batch of cupcakes. And we have 17 cups of flour.

We need to find how many batches can be made.

1st way:

We will get the number of batches when we divide the available cups with cups required for one batch.

Available cups = 17 and required cups for one batch = 3\frac{1}{2} = \frac{7}{2} cups

number of batches = $\frac{17}{\frac{7}{2}}$

$=\frac{17}{1} \times \frac{2}{7}$

$=\frac{34}{7}$ = 4.857

As the number of batches can’t be fraction, we will neglect the fractional part.

2nd way:

Let the number of batches be x.

Then, cups of flour required for batches must be less than available flour

(x)(\frac{7}{2}) < 17

(x)(7) < (2)(17)

7x < 34

x < \frac{34}{7}

x < 4.857

As the number of batches must be an whole number, x becomes 4.

Hence, 4 batches of cupcakes can be made.

Select all of the points that are part of the solution set of the linear inequality shown in the graph below:
Kobotan [32]

Answer:

The answer to your question is below

Step-by-step explanation:

To decide if a point is a solution to the inequality, this point when plotted must be in the shaded area.

(0, 0)      It is a solution of the inequality

(4, -1)      It is not part of the inequality

(-1, 4)      It is a solution of the inequality

(0, -2)     It is not a solution to the inequality

(-2, 0)     It is a solution to the inequality

(-4, 0)     It is a solution to the inequality

Which of the following is true of a person with a high credit score?
egoroff_w [7]

Answer:

The correct answer is :A :They are more likely to pay bills on time.

Step-by-step explanation:

Which of the following is true of a person with a high credit score?

A : They are more likely to pay bills on time.

High credit scores are given to those who pay off their debt with time. Good credit scores are important to get loans. Bad credit scores are allotted to those who do not pay their bills on time. These people face problems while applying loans and either they do not get loans or get it at very high interest rates.
