What i the solution to this equation 6 (x - 5) = 4x + 20

cricket20 [7]

6 (x - 5) = 4x + 20

6x - 30 = 4x + 20

6x - 4x = 20 + 30

2x = 50

$x = \frac{50}{2}$

x = 25

Classify the pair of angles. Then find the value of x.

sleet_krkn [62]

Answer:

3) x = 50, vertical angles.

4) x = 20, supplementary angles

5) x = 14, complimentary angles

Step-by-step explanation:

vertical angles.

vertical angles are equal.

so, you can make this equation:

67 = x + 17

subtract 17 from both sides of the equation

67 - 17 = x + 17 - 17

67 - 17 = x

50 = x

supplementary angles

supplementary angles add up to 180

so, you can make this equation:

7x + 40 = 180

subtract 40 from both sides of the equation

7x + 40 - 40 = 180 - 40

7x = 180 - 40

7x = 140

divide both sides by 7

7x/7 = 140/7

x = 140/7

x = 20

complimentary angles

complimentary angles add up to 90

so, you can make this equation:

4x + 34 = 90

subtract 34 from both sides of the equation

4x + 34 - 34 = 90 - 34

4x = 90 - 34

4x = 56

divide both sides by 4

4x/4 = 56/4

x = 56/4

x = 14

DO use multiplication sign '*' (the STAR) symbol. For the simplifier, xy is NOT the same as x*y or yx. Simplifier thinks that xy is a separate variable. Good example: x*y-y*(x+2). Bad example: xy-y(x+2).DO use '*' when multiplying a variable by an expression in parentheses: x*(x+2). Otherwise, my simplifier will think that you are trying to use a function and will become confused.Use parentheses liberally to avoid any ambiguity. (x+y)/(x-y) is NOT the same as x+y/x-y. x+y/x-y means x+(y/x)-y.OperationsUse '*' (STAR) for multiplication. 2*3 is legal, 2x3 will be misunderstood.Use '^' (CARET) for power. 2^3 means 2 to degree of 3, or 8.Use '/' (FORWARD SLASH) for divisionOnly '(' and ')' (parentheses) are allowed for grouping terms. Curly or square brackets are used for other purposes.

Operation priority: + and - have lowest priority, * and / h

Good Examplesx*y-x*(y+2) <-- '*' is used for multiplications a^b*3 <-- means (a to the degree of b) multiplied by 3 Bad examplesxy-yx <-- variable xy and variable yx are different variables y(x-2) <-- simplifier will think that it is function y of x-2.
