Answer:

The answer to your question is x = 30; y = 14

Step-by-step explanation:

Data

JK = x PR = 20

JL = 21 PQ = y

LK = 18 QR = 12

Process

1.- Find x

Use proportions to find it

JK/PR = LK/QR

Substitution

x/20 = 18/12

Solve for x

x = 20(18/12)

x = 360/12

x = 30

2.- Find y

PQ/JL = PR/JK

Substitution

y/21 = 20/30

Solve for y

y = 21(20/30)

y = 420/30

y = 14

Answer: It is tripled.

Since x and y are proportional, whatever happens to x must happen to y in order for the two values to stay proportional.

How do I solve The sum of a number and 3 is subtracted from 10 the result is 5

meriva

State the given in the question

Given that the sum of a number and 3 is subtracted from, the result is 5

State what is to be found in the question

We are to find the number. In other to achieve this, we would follow the steps below:

Step 1: Represent the number with an unknown

Let x represent the number

Step 2: Interpret the given statement mathematically

If x is the number, then the sum of the number and 3 would be

$x+3$

Then the sum of a number and 3 subtracted from 10 would be

$10-(x+3)$

Finally, when the sum of a number and 3 subtracted from 10, the result is 5, would be

$10-(x+3)=5$

Step 3: Solve for x in the mathematical interpretation of the given statement

The value of x is as calculated as shown below:

$\begin{gathered} 10-(x+3)=5 \\ \text{Open the bracket or the parenthesis} \\ 10-x-3=5 \\ \text{collect like terms} \\ 10-3-5=x \\ 7-5=x \\ 2=x \\ \text{Therefore:} \\ x=2 \end{gathered}$

Hence, the number is 5

Is the length of the hypotenuse of a right triangle with legs that measure 5 cm and 6 cm a rational number or an irrational numb

Brut [27]

Answer:

irrational

Step-by-step explanation:

Use the Pythagorean theorem.

5² + 6² = c²

25 + 36 = c²

c² = 61

7² = 49

6² = 64

61 is between 7² and 8², so it is not rational.
