Answer:
x= -3
Step-by-step explanation:
7 + 2x/3 = 5
Subtract 7 from both sides,
2x/3 = 5-7
2x/3 = -2
Multiply by 3,
2x = -2*3
Divide by 2,
x = -2*3 / 2
x = -3
L=n-2, W=4+L=n+2
A=LW, since L=n-2 and W=n+2 we have:
A=(n-2)(n+2) so it could be this expression or the expansion
A=n^2-4
Answer:
4,000 enroll
Step-by-step explanation:
If 20,000 students apply and the university only accepts 40%, the university accepted 8,000 students.
How many actually enrolled?
Of those accepted students (8,000), 50% enroll.
8,000 / 2 OR 8,000 x 0.50 = 4,000 students actually enroll.
Answer:
The system is inconsistent
Step-by-step explanation:
Given the matrix system solutions in the attachment, we can see that the coefficient of the matrix rank has become zero. This shows that it has no solution.
