Answer:
x=2
Step-by-step explanation:
0.95x +0.05(12-x) = 0.10(24)
Distribute
0.95x +0.6-0.5x= 2.4
add/subtract like terms
0.9x+0.6=2.4
subtract 0.6 from both sides
0.9x=1.8
Divide both sides by 9
0.1x=0.2
multiply both sides by 10
x=2
Hope this helps! Plz award Brainliest : )
Step-by-step explanation:
-Twice means muliply by 2
-The difference of a number and 7 means subtract a number/variable and 7.
-Is equal to 9 means =9
2(X - 7) = 9
The polynomial remainder theorem allows us to calculate the remainder when a polynomial is divided by a linear polynomial:
The remainder of f(x) divided by (x-k) equals f(k).
Thus
f(x)=x^3+3x^2-10x-4 divided by x-3
gives a remainder of
f(3)=27+3(9)-10(3)-4=27+27-30-4=20
Therefore the remainder required is 20.
I'm sorry if I'm wrong but I think the answer is -31
No wait nvm maybe not I'm so sorry I can't remember
