Answer:
A - The sum of a unknown value times 3 and 5. B - The sum of a unknown number subtracted by 2 being multiplied by 4.
Explanation:
A - The sum of a unknown value times 3 and 5. B - The unknown value subtracted by 2, then multiplied by 4.
Step-by-step explanation:
So, lets pick apart the expressions.
We know the variables will be unknown values:
3unknown value + 5
We know that a number in front of a variable is multipication, so:
3 times unknown value + 5
We know there is a addition symbol, which means a sum of two numbers.
So:
3 times a unknown value and the sum of 5
5 is just 5, so we can write it as it is.
This might be read as 3 times both the 5 and unknown value, so we want to make sure they are seperate:
3 times a unknown value plus by 5
So basically, instead of talking about the sum of the two numbers, I used plus so that the numbers are seperate. THis way there is no confusion in the answer.
Next we have 4(x-2)
So first off, x is our unknown value:
4(unknown value-2)
- is subtraction, so:
4(unknown value subtracted by 2)
2 remains as 2.
4 is multiplying the parenthese, so basically, the x-2 is done first. THen it is multiplied by 4. This means the multiplied by 4 should come after the unknown value si subtracted by 2:
The unknown value subtracted by 2, then multiplied by 4.
I used a then to seperate the unkownv alue subtracted by 2 and the multiplied by 4.
