Answer:
1/2
Step-by-step explanation:
-4y = -2x + 10
y = 1/2x - 2/5
The slope is the number in front of the x, so the slope would be 1/2.
Answer:
The lines for each pair of equations are perpendicular, because the slopes for both of these have negative reciprocals.
Step-by-step explanation:
-5x+10y=5
x-2y=-1
2y=x-(-1)
2y=x+1
y=1/2x+1/2
Answer:
67%
Step-by-step explanation:
Cost plus markup = selling price.
Here, the cost was $30 and the selling price was $50. Subtracting $30 from $50, we get $20, which was the dollar amount of the markup.
We now compare this $20 to the original cost ($30):
$20
------- * 100^ = 67%
$30
The markup, as a percentage, was 67%.
So you need to know 32 centimeters in what?
