Answer:
The answer is that x = -20.
Step-by-step explanation:
The equation:
5/2x + 1/2x = 10 + 7/2x
6/2x = 10 + 7/2x
-7/2x + 6/2x = 10
-1/2x = 10
-1/2x * -2 = 10 * -2
x = -20
Proof:
5/2*-20 + 1/2*-20 = 10 + 7/2(-20)
-50 + (-10) = 10 + (-70)
-50 - 10 = 10 - 70
-60 = -60

Answer:
8
Step-by-step explanation:
ok so this is just the first one but i think you use a variable for what you are trying to find out, and well call this x and then u subtract the variable from the product of the rate and the amount, and once you have it, you multiply it but its own conjugate so then u use the binomial that you get to create a function, and you can graph it if you want, and u can use the apothem (the formula involves cos, so you might need a calculator) of the polygon created on your graph to find the domain, which you will then get the 4th root of, which is your answer. anyway, i believe this is what it is, but i may be wrong. hope this helps!
