Answer:
### What is the unitary method?

Total **length** of 15 car train is 240 **centimeters**.

The **unitary method** is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, car is 16 centimeters long.

The length of a 15 car train = Length of each car × Number of cars

= 16×15

= 240 centimeters

Therefore, the length of 15 car train is 240 centimeters.

Answer:
To do this, just multiply 16*15= This equals 240 centimeters.

Explain how you can use inverse operations to find 1.8 divided by 3.

If an angle is acute, an angle supplementary to it is (always,sometimes, or never) acute

Tyler is thinking of a number that is divisible by 2 and by 3. By which of the following numbers must Tyler's number also be divisible?

No, because some angles are obtuse or acute....

Some are not because some are 180 degrees

8,000. You're welcome!

8000 is the answer it was easy what am I in pre k

Please help me. Thanks~! ^^

A. z = -42

B. z = -34

C. z = 30

D. z = 42

The answer is C because you; need to add instead of subtracting to get a positive number.

2 - z / 3 = 12

Multiply both sides by 3 :

3 * 2 - 3 * ( z / 3 ) = 3 * 12

Refine :

6 - z = 36

Subtract 6 from both sides:

6 - z - 6 = 36 - 6

- z = 30

Divide both sides by - 1

- z / - 1 = 30 / - 1

**z = - 30**

answer C

hope this helps!

Multiply both sides by 3 :

3 * 2 - 3 * ( z / 3 ) = 3 * 12

Refine :

6 - z = 36

Subtract 6 from both sides:

6 - z - 6 = 36 - 6

- z = 30

Divide both sides by - 1

- z / - 1 = 30 / - 1

answer C

hope this helps!

the answer to eight hundred and five thousandths is 8.5

It will be 0.805 so yep that will answer your question

Answer: 123 crackers

Step-by-step explanation:

If 1/3 of the box contains sesame seed crackers, then, 2/3 of the box contains whole wheat and cheese flavored crackers.

Total number of whole wheat and cheese flavored crackers = 53 + 29 = 82

Let x be the total number of crackers in the box, so we will have the equation

2/3 x= 82

x = 82 ÷ 2/3; we will get

X =82 x 3/2

X = 123 crackers

Multiplication should be used here. 30 tens means number ten should beadded 30 times. 10+10+...+10 thirty times, which can be written as 10 x30 which gives us the number 300. We get the same answer if the value of10 thirties is required. We can use the same way to get the answer likethe question given in the begging.

The **number **that has the same **value **as 30 tens is 300.

To determine number that has the same value as 30 **tens**, we need to understand the "**place-value"** system. Tens represent second digit in a number, with each ten being worth 10 units.

Since we have 30 tens, we multiply 30 by 10 to find total value.

⇒ 30 × 10 = 300,

Therefore, the number that has the **same **value as 30 tens is 300. This means that 300 represents the quantity of 30 tens or 30 groups of 10, reflecting the concept of place value and multiplication by **powers **of 10.
