Answer:

50 adults and 250 students tickets were sold

Step-by-step explanation:

Given data

Let the number of adults be x and students be y

3x+2y=650------1

x+y= 300---------2

from 2

x= 300-y

put the value of x in 1

3(300-y)+2y= 650

900-3y+2y= 650

900-y= 650

900-650= y

y=250

put the value of y in 2

x+250= 300

x= 300-250

x= 50

Hence 50 adults and 250 students tickets were sold

Robbie, has scored 120 so far this season. He has scored all of his points on 1-point extra point kicks and 3-point field goals.

joja [24]

Answer:

39 and 27

Step-by-step explanation:

GIVEN: Robbie, has scored $120$ so far this season. He has scored all of his points on $1$ -point extra point kicks and $3$ -point field goals. He has made a total of $66$ kicks.

TO FIND: How many of each kick has he made.

SOLUTION:

Lets extra point kicks made by Robbie be $x$

points scored using extra point kick $=1$

field goal kicks made by Robbie $=66-x$

point scored using field goal kick $=3$

Total points scored by Robbie $=120$

Total points scored are the sum of points scored by extra point kicks and field goal kicks.

$1\times x+(66-x)3=120$

$198-2x=120$

$2x=78$

$x=39$

total extra point kicks $=39$

total field goal kicks $=66-39=27$

Hence Robbie made 39 and 27 kicks of extra point kick and field goal kicks respectively.
