If xy=13 and both x and y are positive integers, then what is the sum of x + y? Please show work

Answers

Answer 1

Answer:

14

Step-by-step explanation:

13 is a prime number

so it can only have the positive integer factors {1,13}

So {x,y} = {1,13} or {13,1}

In either case, 1+13 = 14

Answer 2

The sum of x + y is 14 .

What is prime number?

A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29.

According to the question

xy=13

both x and y are positive

As 13 is a prime number

i.e

(x,y) can be only 1 or 13 .

To get 13 as product of xy

(x,y) must be equal to  (1,13) or (13,1)

Therefore,

the sum of x + y  = 13 + 1

                           = 14

                     

Hence, the sum of x + y is 14 .

Step-by-step explanation:

3^4 ⋅ 3−^9

When multiplying exponents and the bases are the same, we can add the exponents

a^b * a^c = a^ ( b+c)

3^4 ⋅ 3−^9

3^( 4-9)

Complete question:

Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50. Let SSS represent the number of stacks of pancakes that Benjamin buys. 1) Which inequality describes this scenario?

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Cost of chocolate milk = $3.25

Cost of pancakes = $5.50 (stack of 4)

Number of stacks of pancakes purchased = S

Maximum amount spent ≤ $30

Cost of chocolate + (Cost of pancake stack * number of stacks) ≤ $30

3.25 + 5.50S ≤ 30

5.50S ≤ 30 - 3.25

5.50S ≤ 26.75

S ≤ 26.75 / 5.50

S ≤ 4.86

Hence maximum number of pancake stacks he can purchase without exceeding budget = 4

Hence total number of pancakes = number of stacks * number in a stack

= 4 * 4

= 16

Answer:

Chose option have answer 3.25+5.50S [tex]\leq[/tex] 30

16 pancakes
