The problem isn't provided to solve for a matrix
I think it is 9 - x because 81-x^2/9-x = 9-x
Answer:
x = -1, y = 1.5
Step-by-step explanation:
3x + 6y = 6 -----> x + 2y = 2
-3x + 2y = 6 -----> -3x + 2y = 6
------------------
4x = -4
x = -1, y = 1.5
Answer:

Step-by-step explanation:
To begin simplifying this, we can first divide the coefficients, giving us:

We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:

Now, simplifying this gets:

Answer:
60
Step-by-step explanation:
50%=.50
160×.50=80
160+80=240
25%=.25
240×.25=60
60 is the final number
