Exponents are hard but think about it like addition, that number tells you how many times to add that number to itself. To write the equation put the number and then the exponent on the top right of that number. Your welcome!
Answer:
X=3-(y/2)=8
Step-by-step explanation:
suppose the numbers is X
3 less than half the product of a number is 8
X= 3- (y/2)=8
Given:
Total number of coins (Quarters and dimes) = 60
Total amount = $12.45
To find:
The number of quarters and dimes.
Solution:
Let x be the number of quarters and y be the number of dimes.
We know that,
1 quarter = 0.25 dollar
1 dime = 0.10 dollar
Total coins: ...(i)
Total amount: ...(ii)
From (i), we get
...(iii)
Putting this value in (ii), we get
Divide both sides by 0.15.
Putting x=43 in (iii), we get
So, the number of quarters is 43 and the number of dimes is 17.
Therefore, the correct option is b.
