Answer:
53
Step-by-step explanation:
Let x be the number of children tickets sold and y be the number of adult tickets sold. Then
x+y=128.
The cost of x children tickets is $5.10x and the cost of y adult tickets is $9.70y, so
5.10x+9.70y =896.60.
From the first equation,
x=128-y,
then

53 adult tickets were sold.
4a - 3b
4(5) - 3(- 2)
20 + 6
26
26 is your answer.
89 divided by 7 + 46^2 = 2128.71428571...
