Number one would be 13 because you have to add the x to both sides which will leave you with 2x=26 then you have to divide by 2 and you will get x=13. Number two is 7 7/8 because you have to add the 1/3x to the other 1/3x to get 2/3x= 5 1/4 so then you divide both sides by 2/3 and to divide a fraction you do keep change flip so it would be 21/4 times 3/2 which would be 63/8 which simplifys to 7 7/8.
Answer:
Correct me if Im wrong but I think that it is 3 to the -5th power
Step-by-step explanation:
Answer:
<h2>R-{5}</h2>
Step-by-step explanation:
f(x)=x²-25=(x-5)(x+5)
g(x)=x-5
(f/g)(x)=<em>(x-5)</em>(x+5)/<em>(x-5)</em>=x+5; for x≠5
D=R-{5}
Answer: ? = 72
Step-by-step explanation:
We will set up a proportion to solve.

Now, we will cross-multiply.
? * 35 = 56 * 45
35? = 2,520
? = 72
Area is base times height, so take the 12 and 16 and multiply them, you will get 192 which is your answer
