Lets say y is number of adult tickets and x is number of student tickets
x+y=348
2x+y=348
(2x since I know that the student tickets are twice as much as adult tickets)
I now know that that student tickets make up 2/3 of the total number of tickets and 1/3 make up the number of adults tickets. So...
1/3 x 348= 116 adult tickets
2/3 x 348=232 student tickets
1. 25 + 3u = 2u
-3u = -3u
25 = -u
-25=u
2. 14x - 8 = 6x
8x - 8 = 0
8x = 8
x=1
3. 8.5 - 3z = -8z
8.5 = -5z
-1.7 = z
4. 9m + 14 = 2m
7m + 14 = 0
7m = -14
m = -2
It is equal to 2(x)^3 because pemdas, exponnets come before multiplication so it would be x^3 then multiply whatever that is by 2
2x^3 is answer (4th choice)
8x + 2 > 34
-2 -2
8x > 32
8x (÷ 8) > 32 (÷ 8)
x > 4
so x can equal any number from 5 and infinity
Hope I helped !!! :)
