Answer:75 children
Step-by-step explanation: Let the number of children will be x, so the number of adults will be 215-x
Making equation: 3x+5(215-x)=925
3x+1075-5x=925
-2x=925-1075
-2x=-150
x=75

Answer:
2x2 matrix
Step-by-step explanation:
Given
Dimension of matrices A = 2x2 matrix
Dimension of matrices B = 2x1 matrix
The dimension of matrix AB can be gotten by cancelling the row of matrices 1 and column of matrices 2.
After cancelling both row and column, the remaining dimension will be 2x2 matrix. Hence the dimension of AB is 2x2 matrix
