Solve for x:
(13 x - 5) (14 x - 36) = 0
Split into two equations:
13 x - 5 = 0 or 14 x - 36 = 0
Add 5 to both sides:
13 x = 5 or 14 x - 36 = 0
Divide both sides by 13:
x = 5/13 or 14 x - 36 = 0
Factor constant terms from the left hand side:
x = 5/13 or 2 (7 x - 18) = 0
Divide both sides by 2:
x = 5/13 or 7 x - 18 = 0
Add 18 to both sides:
x = 5/13 or 7 x = 18
Divide both sides by 7:
Answer: x = 5/13 or x = 18/7
The inequality that describes the calories burned is 7x + 9y ≥ 441
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
let x represent the number of minutes of running and y represent the number of minutes of swimming, hence:
7x + 9y ≥ 441
The inequality that describes the calories burned is 7x + 9y ≥ 441

Answer:
The answer is x=12
Step-by-step explanation:
3x - 6 = 30
3x-6+6=30+6
3x=36
To find x divide both sides by 3.
3x/3=36/3
x=12
Answer:
x = 41; B = 41°; A = 77°
Step-by-step explanation:
All of the angles add up to 180 so to solve for X you do (x) + (2x-5) + (62) = 180. Solve for X and you get 41. Lastly plut the answer back into the equation.
