Answer: 6
Step-by-step explanation: 8 x 4 = 32 leaving 6 extra apples
We can solve this system of equation by reduction method.
d+e=15
-d+e=-5
-------------------
2e=10 ⇒e=10/2=5
-(d+e=15)
-d+e=-5
-----------------
-2d=-20 ⇒d=-20/-2=10
therefore: d=10; e=5
Answer: d.(10,5)
5:2 and 14:8 are not proportional, 3 to 4 and 24 to 18 are also not proportional, 5:6 and 2:8 are also not proportional, and 7 to 4 and 17.5 to 10 are also not proportional. 7 inches in 9 hours and 42 inches in 54 hours is proportional. 12 players from 21 teams and 15 players from 24 teams are NOT proportional.
Answer:
In mathematics, the determinant is a scalar value that is a function of the entries of a square matrix. It allows characterizing some properties of the matrix and the linear map represented by the matrix.
