<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the total number of problems that were on the text, y represent the time to be spent, hence:
y = x/8
Also:
y - 6 = x/10
x/8 - 6 = x/10
x = 240
The number of problems that were on the text was 240 problems.

Answer: Forgot to divide at the end
Step-by-step explanation:
To figure out your friend's error, solve the equation yourself.
- Distribute the 5 to get 25x+30
- Combine like terms in the first equation toget 25x-3=25x+30
- Add 3 to the other side.
When we do this, we realize adding 3 would make it 33. This shows that the friend likely forgot to divide by 25 to completely isolate x, and stopped at that step.
18 is the answer to the question 5 divided by 8 is .625 so you have 17.625 round to the nearest whole number gives you 18 lol. Heyy and be a true one and mark me the brainlest answer :)
Answer:
Let x be the bigger number, and y be the smaller number.
Since the difference is 82,
Substitute x in:

Answer is 10:7</h3>
=======================================================
Explanation
It sounds like you want the decimal number to become a whole number. If so, then one way is to multiply both parts by 10 to move that decimal point over one spot to the right
3*10 = 30
2.1*10 = 21
The ratio 3:2.1 is equivalent to 30:21
-----
Then notice how 30 and 21 have the greatest common factor 3. Divide both parts by 3 so we can fully reduce this ratio
30/3 = 10
21/3 = 7
The ratio 30:21 simplifies fully to 10:7
The numbers 10 and 7 do not have any factors in common, other than 1, so we cannot reduce 10:7 any further.
