DrWLS gave you help in your other posts. What kind of help can you possibly need in adding three numbers?
We don't don't do homework on the Jiskha board. We try to show students how to do the work.
i need help to solve 3(x-4)=48
You should not piggy back on another question. Your question will get answered quicker if you click on Post a New Question at the top of the board.
3(x-4)=48
clear the partentheses.
3x - 12 = 48
get x on one side and numbers on other.
3x = 48 + 12
combine terms.
3x = 60
divide both sides by 3
3x/3 = 60/3
x = ??
To find the total of three numbers, you need to add them together. In this case, the three numbers are 212, 21, and 422. Here's how you can calculate the sum:
1. Start by adding the first two numbers, 212 and 21.
- Add the digits in the rightmost place value, which is the ones place: 2 + 1 = 3. Write down the 3.
- Move to the next place value, which is the tens place: 1 + 2 = 3. Write down the 3.
- Since there are no more place values to add, the result for the first two numbers is 33.
2. Now, take the sum you got from step 1 (33) and add it to the third number, 422.
- Add the digits in the rightmost place value, which is the ones place: 3 + 2 = 5. Write down the 5.
- Move to the next place value, which is the tens place: 3 + 2 = 5. Write down the 5.
- Move to the hundreds place: 4 + 0 (since there is no digit in the corresponding place for the second number) = 4. Write down the 4.
- Since there are no more place values to add, the final result is 545.
So, the total of the three numbers 212, 21, and 422 is 545.
