i can not give the answer unless you still cannot find it after these steps but I have steps that might help
1. Set the matrix (must be square).
2. Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.
3. Multiply the main diagonal elements of the matrix - determinant is calculated.
Answer:
The answer after solving is 7/16
Step-by-step explanation:
The solutions involves fraction addition & fraction subtraction.
The solution is attached in the picture:
Sid wrapped 8 gifts.
Look at the equation Sid wrote to caclulate the cost to wrap each gift. (6.80 + 7.35) / 8. 6.80 represents the total paid for wrapping paper. 7.35 represents the total amount paid for ribbon. Knowing that information, using the equation, and knowing who Sid wrapped gifts for, we can infer Sid wrapped gifts for 8 cousins.
Answer:
x=a-d/c+b
Step-by-step explanation:
a-bx =cx+d
collect like terms
a-d=cx+bx
a-d=x(c+b)
x=a-d/c+b
