Answer:
2 and 3
Step-by-step explanation:
Answer:
(-5,5)
Step-by-step explanation:
Multiply the first equation by -2,and multiply the second equation by 1.
−2(x+5y=20)
1(2x−7y=−45)
Becomes:
−2x−10y=−40
2x−7y=−45
Add these equations to eliminate x:
−17y=−85
Then solve−17y=−85for y:
(Divide both sides by -17)
y=5
x+5y=20
Substitute 5 for y in x+5y=20:
x+(5)(5)=20
x+25=20(Simplify both sides of the equation)
x+25+−25=20+−25(Add -25 to both sides)
x=-5
Answer:
6 three-point shots
Step-by-step explanation:
Amount of points scored in nine games = 162 points
If he scored the same number of three-point shots in each game, the nmber of three points shots he made in each game will be expressed as;
1 game = x points
Since 9 games = 162 points
We will cross multiply and get s:
9 * x = 162 * 1
9x = 162
Divide both sides by 9;
9x/9 = 162/9
x = 18
Hence he has made 18 points in one game.
The number of 3 points shot made per game will be 18/3 = 6 three-point shots
