4x5-(2 (2) - 2 ) = 14
(18/ 3) + (3 (2) - 7) 8
Answer:
x = 6/7, y = 1/2
Step-by-step explanation:
7x + 2y = 7
-14x + 2y = -11
1) 7x + 2y = 7
2y = 7 - 7x
2) -14x + 2y = -11
-14x + 7 - 7x = -11
- 21x = -11-7
- 21x = - 18
x = 18/21 = 6/7
3) 2y = 7 - 7x = 7 - 7*(6/7) = 7 - 6 = 1
2y = 1
y = 1/2
Answer:
Therefore,
The actual area of the basketball court if the scale drawing is
11.75 inches by 6.25 inches is
Step-by-step explanation:
