1 answer:
Answer:
Games = x = 9
Rides = y = 5
Step-by-step explanation:
Let
Games = x
Rides = y
x + y = 14 (1)
1.25x + 2.25y = 22.50 (2)
From (1)
x = 14 - y
Substitute x = 14 - y into (2)
1.25x + 2.25y = 22.50
1.25(14 - y) + 2.25y = 22.50
17.5 - 1.25y + 2.25y = 22.50
- 1.25y + 2.25y = 22.50 - 17.5
y = 5
Substitute y = 5 into (1)
x + y = 14
x + 5 = 14
x = 14 - 5
x = 9
Games = x = 9
Rides = y = 5

Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
__9x__ = __108___
9 9
x = 12
3a - 4b = 21
check (-2 , -3)
3(-2) -4(-3) =21
-6 +12 = 21
6 does not = 21 so NO
check (0 , 7)
3(0) -4(7) =21
0-28=21
-28 does not equal 21 so NO
check (-3 , -2)
3(-3) -4(-2) =21
-9 +8 = 21
1 does not = 21 so NO
check (7 , 0)
3(7) -4(0) =21
21 = 21
