2km=2000m
25m=25m
2500cm=25m
3000mm=3m
Hence the longest is 2km=2000m
<span>We have 75 mL of 4% sugar solution.
We have to add a 30% sugar </span><span>solution to make a 50% </span><span>sugar solution.
75 * .04 + .30x = .50 * (75 +x)
3 + .30x = 37.5 +.50x
I can't get the equation to solve.
Did you type it correctly? For one thing, you have the percentages typed as .30 % and 4%. Are the decimal places in the correct positions?
Also, no matter how much 30% sugar solution you add, it will NEVER increase to 50%.

Kahal made an error in step 1 in his calculation.
Step-by-step explanation:
Inequality solved by Kahal;
4x-4>20
Steps used by Kahal
step 1: 4x-4>20
step 2: 4x>16
step 3: x>4
Kahal made mistake in first step where he subtracted 4 from 20. because to eliminate 4 we will add 4 on both sides which will make;
Step 1: 4x-4+4 > 20+4
4x>24
Thus,
Kahal made an error in step 1 in his calculation.
