4/10 is also equal to 2/5 and 2+2 equals four therefore you would get 4/5 as your final answer
Answer:
$60
Step-by-step explanation:
Let's say we need t $2 bills and v $5 bills.
We need 9 more $2 bills than $5 bills, so:
t = 9 + v
We also know that the amount of money in t $2 bills is 2 * t = 2t. The amount of money in v + 9 $5 bills is 5 * (v + 9) = 5v + 45. These amounts are equal:
5v + 45 = 2t
Plug v + 9 in for t in 5v = 2t + 18:
5v = 2t + 18
5v = 2 * (9 + v) + 18
5v = 18 + 2v + 18
3v = 36
v = 12
We have 12 $5 bills, so that total cost is 12 * 5 = $60.

If they're similar it would be 72, 36x2=72.
2x + 7 = 3
2x = 3 - 7
2x = -5
x = -5/2
2x-1=0
2x=1
x=1/2
x+5=0
x=-5
Final answer: B
