Subtract 10 from both sides :
-3y + 10 - 10 = -14 -10
3y = -24
divide both sides with 3 :
y = -8
Answer: The whole journey is 3,250km.
Step-by-step explanation:
20% = 650km
20 * 5 = 100%
650 * 5 = 3,250km
52.8 is the answer.
Hope this helps!
4+5x=1
subtract 4 from each side
5x=-3
divide both sides by 5
x = -3/5
Use the cumulative frequencies to figure out what the individual frequencies would be. Check out the attached image for the table of x values with their corresponding frequency (f) values. Note how the partial sums add up to the cumulative frequency values.
Once you know the frequency f values, multiply each x and f pair together in each row. The column labeled "x*f" represents each product. Afterward, add up everything in the x*f column to get the final answer 6.8
