Linear Equation
Flashcards do conjunto (5)
- 1If in the equation x + 2y = 10, the value of y is 6, then the value of x will be-2
- 22x+ 5y = 0 Is this a Linear EquationYes it is a linear equation with two variables.
- 3Write in a form of equation the number added to twice the number gives 21x + 2x = 21
- 4The sum of two numbers is 25. One of the numbers exceeds the other by 9. Find the numbers.According to question, x + x + 9 = 25
⇒ 2x + 9 = 25
Therefore, the two numbers are 8 and 17. - 5The difference in the measures of two complementary angles is 12°. Find the measure of the angles.Complement of x = 90 - x
Given their difference = 12°
Therefore, (90 - x) - x = 12°
⇒ 90 - 2x = 12
⇒ x = 39
Therefore, 90 - x = 90 - 39 = 51
Therefore, the two complementary angles are 39° and 51°
