How to isolate a variable

Mathematics
1 answer:
Oksana_A [137]3 years ago
5 0

Answer:

The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number. By repeating this process, we can get the variable isolated on one side of the equation.

A survey of 394 children given at a local elementary school showed that 150 like chocolate ice cream 175 like pistachio ice crea
Airida [17]

Answer:

e) 294 children

Step-by-step explanation:

Since there are 394 children in total and 169 do not like either ice-cream, the number of children who likes at least 1 ice cream is

394 - 169 = 225 children

Out of 225 children, 150 like pistachio icecream, some of them may like both. Therefore the number of children who likes ONLY chocolate icecream is

225 - 150 = 75 children

Similarly, out of 225 children, 175 like chocolate icecream, some of them may like both. Therefore the number of children who likes ONLY pitaschio icecream is

225 - 175 = 50 children

So the total number of children who like at most only 1 kind of ice cream is

75 + 50 + 169 = 294 children

Question 1 of 4
Aliun [14]

OB. The digits in the millions period are 41, the digits in the thousands period are 000, and the digits in the ones period are 138.

The digits of a number can be classified into into 3 groups and each such group is called a period.

Here, we are give a number 41,000,138.

In this number, the million period consists of

ten millions - 4

and millions - 1

Hence the digits in the million periods are 41

The thousand period consists of all zeroes, hence the digits in thousand periods are 000.

The ones period contains-

hundreds - 1

tens - 3

and ones - 8

Thus, the digits in the ones period are 138

Hence, option B is the correct answer.
