i have 25 coins, x of them are R5 coins and the rest are R2 coins. an expression in term of x for the number R2 coins i have is?
25 = x + nR2
nR2 = 25 - x
Let's break down the problem step by step:
Step 1: Determine the total number of coins you have.
You mentioned that you have a total of 25 coins.
Step 2: Identify the number of R5 coins.
You mentioned that you have x R5 coins.
Step 3: Calculate the number of R2 coins.
To find the number of R2 coins, subtract the number of R5 coins (x) from the total number of coins (25).
Number of R2 coins = Total number of coins - Number of R5 coins
Therefore, the expression in terms of x for the number of R2 coins you have is:
Number of R2 coins = 25 - x
To find the expression in terms of x for the number of R2 coins you have, let's break down the information provided.
We know that you have a total of 25 coins, and x of them are R5 coins. This means that the remaining coins, which are not R5 coins, must be R2 coins.
So, to calculate the number of R2 coins, we need to subtract the number of R5 coins (x) from the total number of coins (25). The expression would be:
Number of R2 coins = Total number of coins - Number of R5 coins
Number of R2 coins = 25 - x
Therefore, the expression in terms of x for the number of R2 coins you have is 25 - x.
