The answer is 66.75
I would suggest multiplying 2 in (2x+1) by 2 5/8 first, then multipling 4 by 2 5/8. This will garner you 10 and 5.25. Distribute the 9 into the (). You'll then get 10.5+47.25+9
Add and you will get 66.75
Let the number of half dollars be x,
number of quarters = x + 2
amount of half dollars = 0.5x
amount of quarters = 0.25(x + 2)
= 0.25x + 0.5
total amount = 0.5x + 0.25x + 0.5
= 0.75x + 0.5
0.75x + 0.5 = 11.75
0.75x = 11.25
x = 15
number of quarters = x + 2
= 15 + 2
= 17
There are 17 quarters and 15 half dollars.

1
Step-by-step explanation:
Substitute the value of the variable into the expression and simplify.
4-2-1=1
Answer:
4(2n-5)
Step-by-step explanation:
So we know Valerie has 5 less than double the number of brad's books. Brad has n books, so make that 2n to double it.
Because she has 5 less than that, the expression is now 2n-5. The is the total of Valerie's books.
We know that Brad has 4 times the number of Valerie's books, so just multiply that expression by 4.
The final answer is 4(2n-5).
You're welcome. :)
Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative. Take a look at some examples. The distance from 5 to 0 is 5 units.
