Let x tickets sold be adults, then (1024-x) were of childrens tickets, 9x+(1024-x)4 = 7680. The above equation is for total money solve it you will get x=720 hence, number of adult tickets were 720 and number of child tickets were 300 :)
Step-by-step explanation:
sqrt(5x)×(sqrt(8x²) - 2×sqrt(x)) =
sqrt(5x × 8x²) - 2×sqrt(5x × x) =
sqrt(40x) × x - 2x × sqrt(5) =
2x×sqrt(10x) - 2x×sqrt(5)
therefore, the last option is correct.
Thus should be fun I know I might do
250 miles on 8 gallons of fuel
means 250 miles were traveled on 8 gallons, so an average of 250mi/8gal = 31.25 mpg
(3^2)^-2
9
9^-2 = 1/9^2 ---> 1/81
should be 1/81
