7/5 x 5/4
= 1 3/4
One and three fourths
The answer is D: when the ticket price is $15, a total of 120 people visited the art show
((3e^9b-4b-9)-(3e^9a-4a-9))/(2)
D. (5/9v - 5/9)
<u>Step-by-step explanation:</u>
(2/9v)- (-1/3v+ 5/9)
Since it is subtraction, we have to change the sign of the second expression that is after the (-) sign.
= (2/9v + 1/3v - 5/9)
Since we have different denominators, we have to take LCM of 3 and 9 as 3, so the expression becomes,
= (2/9v + 3/9v - 5/9)
= (5/9v - 5/9)
