T= 149/300. To understand how I got it, I did 75x(8t - 4)= -2
Answer:
X =1/39
Step-by-step explanation:
1/2+ 6X = 5/6 - 7X Transposing terms
6X + 7X =5/6 - 1/2
13X = 5/6 - 3/6
13X = 2/6 simplifying
13X = 1/3
and transposing 13:
X =1 / (13x3) reducing
X= 1/39

Answer:
11. a
12. c
13 a
Step-by-step explanation:
Well you have to make the powers line up so we know r^4 is the highest and you work your way down so
0r^4-5r^3-4r^2-3r
R^4+0r^3-4r^2+3r
So now that they are lined up by power we solve (keep in mind that the 0r's are place holders and have no value)
R^4-5r^3-8r^2
That's your answer
