Answer: 4:1
Step-by-step explanation: I think the answer is 4:1. I think this because 20% of 2500, would be 500. So 2500-500=2000. So the ratio would be 2000:500. Then we simplify 2000:500, by dividing 2000 by 500, and dividing 500 by 500. 500 / 500 = 1. 2000 / 500 = 4, so the answer is 4:1. (I am sorry if I am incorrect)
Answer:
Step-by-step explanation:

y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)
<em><u>Solution:</u></em>
Given that, we have to write the equation of the line whose slope is 5 and y intercept is (0,4)
<em><u>The equation of line in slope intercept form is given as:</u></em>
y = mx + c ---- eqn 1
Where, "m" is the slope of line and "c" is the y - intercept
Given that, slope = m = 5
y intercept is (0, 4)
So, c = 4
<em><u>Substitute c = 4 and m = 5 in eqn 1</u></em>
y = 5x + 4
Thus the equation of line is found
The estimated sum of 196 and 482 is 700.
We do estimates when we do mental calculation. We relate the number to the nearest number that can easily be computed mentally.
196 is near 200 so we round it up to 200
482 is near 500 so we round it up to 500
Thus, 200 + 500 = 700.
700 is the estimated sum.
