A test has 20 questions and worth 100 points. The test consists of TrueFalse questions worth 11 points each. How many multiple questions are on the test?

To determine the number of multiple-choice questions on the test, we first note that there are 20 questions in total, with each True/False question worth 11 points. Since the total score is 100 points, we can find the number of True/False questions by dividing the total points by the points per True/False question: 100 / 11 ≈ 9 (rounding down since we can't have a fraction of a question). This means there are 9 True/False questions, leaving 20 - 9 = 11 multiple-choice questions on the test.


What is the solution of the equation x plus 5 equals 16?

Thje 'solution' is the number that 'x' must be in order to make the equationa true statement.x + 5 = 16Subtract 5 from each side of the equation:x = 11


Is there an answer for 8 plus 3x equals x plus 11 plus 2x?

No because: 8+3x=x+11+2x (rewrite equation) 8+3x=11+3x (combine like terms) 8=11 (subtract 3x from both sides) This is obviously a false statement, so there is no solution or answer to the equation.


What is a true sentence in math?

A sentence is made up of two expressions connected by an equal sign or an inequality sign (such as <). If there's an '=' sign, it's an equation, otherwise it's an inequality. A sentence with a variable in it is called an open sentence - you need to put a number in for the variable to see whether it is true or false. If the sentence has no variable in it, then we can decide whether it is true or false. Examples of a true sentences: 1 + 6 = 7 4 > 2 5 + 17 = 11 times 2 .


Is (2-11) a solution for -3x 2y 5?

To determine if (2, -11) is a solution for the equation (-3x + 2y = 5), substitute (x = 2) and (y = -11) into the equation. This gives (-3(2) + 2(-11) = -6 - 22 = -28), which does not equal 5. Therefore, (2, -11) is not a solution to the equation.
