Answer:
8/13
Step-by-step explanation:
Let the number be x
if five times a number added to 4 is divided by the number plus 6 the result is nine halves
- five times the number = 5x
- five times a number added to 4 = 5x+4
- five times a number added to 4 is divided by the number = (5x+4)/x
- five times a number added to 4 is divided by the number plus 6 = (5x+4)/x + 6
- nive halves = 9*(1/2)
five times a number added to 4 is divided by the number plus 6 the result is nine halves
(5x+4)/x + 6 = 9(1/2)
=>(5x+4)/x + 6 -6 = 9(1/2) -6 = 9/2-6 = (9-6*2)/2 = -3/2
=>(5x+4)= -3/2 *x= -3x/2
=>2(5x+4) = -3x
=> 10x +8 = -3x
=> 10x+3x = 8
=> 13x = 8
=> x = 8/13
Thus, the number is 8/13

Answer:

Step-by-step explanation:
To start, you need to find the equation of both of these lines. For the orange one, the slope can be found with the points (-5,0) and (0,-4), where there is a drop of 4 for a run of 5. This is a slope of -4/5, and a y-intercept of -4. For the purple line, you can use the points (-2,0) and (0,1), where there is a rise of 1 for a run of 2 or a slope of 1/2 and a y intercept of 1. Therefore, the two equations are:


You can now set them equal to each other:

Add 4 to both sides:

Multiply both sides by 2:

Multiply both sides by 5:

Subtract 5x from both sides:

Divide both sides by -13:
