The score on a trivia game is obtained by subtracting the number of incorrect answers from twice the number of correct answers.
guajiro [1.7K]

Answer: the player answered 30 questions correctly.

Step-by-step explanation:

Let x represent the number of questions that the player answered correctly.

Let y represent the number of questions that the player answered incorrectly.

The number of questions that the player answered is 40. It means that

x + y = 40- - - - - - - - - - -1

The score on the trivia game is obtained by subtracting the number of incorrect answers from twice the number of correct answers. If the player obtained a score of 50, It means that

2x - y = 50

y = 2x - 50

Substituting y = 2x - 50 into equation 1, it becomes

x + 2x - 50 = 40

3x - 50 = 40

3x = 40 + 50 = 90

x = 90/3

x = 30

5. A farmer puts apples into 36 crates. Each crate has 25 kilograms of apples in it. She sells 486,235 grams of apples. How many
Lynna [10]

There would be 413,765 kilograms after selling 486,235 grams of apples

How many grams make a kilogram?

In each kilograms, there are 1,000 grams, which means we need to first of all convert the total number of apples in kilograms to grams.

Each crate has 25 kilograms of apples in it

1 crate =25 kilograms

36 crates=36*25 kilograms

36 crates=900 kilograms

1 kilogram=1000 grams

900kilograms=1000*900

900 kilograms=900,000 grams

The number of grams left after having sold 486,235 grams of apples, in essence, the quantity of apples left thereafter is 900,000 grams minus the 486,235 grams of apples sold

apples left=900,000-486,235

apples left= 413,765 kilograms
