Symmetric property of equality to show that 3a = 4b, then 4b = 3a?

What is symmetric property of equality?

The symmetric property of equality is a simple property that says we can interchange the sides of an equation without changing the truth-value of the equation. That is, if a = b, then b = a. Each side of the equation can be thought of as the mirror image of the other

We have the following information available from the question is:

We have to determine the which property can be used to show that if 3a = 4b, then 4b = 3a

Now, According to the question:

3a = 4b

4b = 3a (both are equal)

This property is used to simplify the equations, to reverse the equations, and also for proofs in numerical and non-numerical logic.

3/7*336=144

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

If out of 28 students, 12 students packed their lunch.

The number of students who packed their lunch out of 336 students is 144 students.

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

Example:

3 miles in 3 hours.

1 mile in one hour.

We have,

In a class of 28 students, 12 students packed their lunch.

We can write this as:

28 students = 12 students packed lunch ______(1)

We have to make 28 students into 336 students.

This can be done by multiplying 12 on both sides of the equation (1)

Multiply 12 on both sides.

12 x 28 students = 12 x 12 students packed lunch

336 students = 144 students packed lunch

Thus,

The number of students who packed their lunch out of 336 students is 144 students.

What must be the length of PQ in order for AJKL to be
similar PQR

Answers

9514 1404 393

Answer:

  (d)  18

Step-by-step explanation:

If ΔJKL ~ ΔPQR, then we must have ...

  PQ/JK = QR/KL . . . . . ratios of corresponding sides are the same

  PQ = JK×QR/KL = 12×9/6 = 2×9

  PQ = 18

Answer:

18

Step-by-step explanation:

The scale factor for this is 1.5,

JL = PR

JL is 14, and PR is 21, 14 * 1.5 = 21

KL = QR

KL is 6, and QR is 9, 6 * 1.5 = 9

So we do the same for JK and PQ

Since PQ is 12, we need to find what 12 * 1.5 is.

12 * 1.5 = 18

PQ = 18
