Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let me help out.
To get an expression that is equivalent to 18 - 7, you will have to know the value of 18-7 first. This will be:
= 18 - 7
= 11
Since we know that 18-7 = 11, then from the options that you're given, you'll find the one that is also equal to 12 which will be the answer.
For example, let's say you're given the options of a. 20 - 6 and b. 3 + 19 - 11.
20 - 6 = 14. This means that it isn't an equivalent of 18-7.
3+19-11 = 11. So, this is an equivalent of 18-7.
Idk 3x+1-2 all I know simplifying terms look and ask your teacher or look at khan academy it’s free
Then it would be : 1/4 * 128 = 32
So, original price will be 128 - 32 = 96
Answer:
$220.18
Step-by-step explanation:
The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:
In Jayden's case:
- A(n)=$400
- r=12%=0.12
- n=5 years
- k=12 Months
We want to determine the amount Jayden put in the savings account.
Jayden earned $220.18 from doing odd jobs.
