What is the unitary method?

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.

What is the solution to the equation?2 - Z/3 = 12

Please help me. Thanks~! ^^



A. z = -42

B. z = -34

C. z = 30

D. z = 42

Answers

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!

Mikaela friends brought a big box of crackers to the movies. 53 crackers are whole wheat and 29 are cheese flavored. The remaining 1/3 of the box contains sesame seeds crackers. how many crackers are in the box altogether?

Answers

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

What number has the same value as 30 tens

Answers

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.
