Find the relevant fraction: 36/45
Reduce this by dividing top and bottom by 9, giving 4/5
Now multiply top and bottom by 20. This will make the denominator 100.
4/5 = 80/100
80/100 = 80%
So 36 is 80% of 45.

If two lines intersect, then there are two possibilities
A) The lines intersect at exactly one point. This happens if the slopes of the two lines are different (the y intercepts may or may not be the same).
B) The lines intersect at infinitely many points. This happens when both slopes are the same and when both y intercepts are the same. In short, the two equations are identical. Often they may be written in different forms. For example, the equation y = 2x+1 and 2y = 4x+2 are the same equation. Divide everything in equation (2) by 2 and you'll get equation (1).
are parallel?
a) 2x + 5y = 6 and 5x + 2y = 10
b) 3x + 4y = 12 and 6x + 8y = 12
2x+ 5y=6 and -2x + 5y = 14
d) 3x + 4y= 12 and 6x - 8y = 20

Answer:
b) 3x + 4y = 12 and 6x + 8y = 12
Step-by-step explanation:
they share the same slope
Final answer:
In this question, we are asked to determine which two lines are parallel. By finding the slopes of the given lines, we can determine if they are parallel or not.
Explanation:
In order for two lines to be parallel, they must have the same slope. To determine the slope of a line, we can rearrange the equation into slope-intercept form (y = mx + b), where m represents the slope. Let's find the slopes of the given lines:
a) 2x + 5y = 6 --> 5y = -2x + 6 --> y = (-2/5)x + 6/5 --> slope = -2/5
b) 3x + 4y = 12 --> 4y = -3x + 12 --> y = (-3/4)x + 3 --> slope = -3/4
c) 2x + 5y = 6 and -2x + 5y = 14 both have the same slope of -2/5, so these lines are parallel.
d) 3x + 4y = 12 and 6x - 8y = 20 do not have the same slope, so these lines are not parallel.
