Answer:
You wrote the numbers from 1 to 9: 9 digits.
You wrote the numbers from 10 to 99: 90*2 = 180 digits.
You have written 189 digits.
Then you wrote another 1994 - 189 = 1805
All the numbers from 100 to 999 have 3 digits
So you wrote 1805/3 = 601 2/3
This means 601 full numbers and 2 digits from the 602. number.
So 100 + 601 - 1 = 700 was the last number you wrote.
Do you agree?
Answer:
7.35
Step-by-step explanation:
5 pounds -> 5.25
1 pound -> 1.05
7 pounds-> 7.35
Here are your equations:
x and 3x
How to set up:
2(x)+ 2(3x) = 44
Simplify:
8x = 44
Divide:
x = 5.5
Plug back in to find values:
Width = 5.5
Length = 16.5
Hope this helps!! :)
I'll get you started. Let x and y be the two numbers. we have: x + y = 74 (sum is 74) x = 4y - 6 (the number x is six less than 4 times y) Now that you have the equations use an algebraic techniques to eliminate one variable thereby solving for the other. If you need more help add a comment to your question.
