Answer:
150 one point throws, 165 two points throws and 110 three points throws
Step-by-step explanation:
Let x be the number of free (one point) throws.
The number of free throws Sarah made was 15 less than the number of two-point field goals she made. If y is the number of two points throws, then

so the number of two points throws 
The number of two-point field goals that Sarah made was 55 less than double the number of three-point field goals she made. If z is the number of three points throws, then

so the number of three points throws 
The total score is 810 points, so

Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2
$10.50
Explanation:
Let x be the cost of the individual books. Then 24.81=3x−6.69
3x= 24.81+ 6.69 =31.50
x=31.50/3=10.50
