I might be misreading something here but if:
x^5+243=0 subtract 243 from both sides
x^5=-243 raise both sides to the 1/5 power (or take the fifth root of both sides)
x=-3
So there is only one solution, x=-3
Answer:
13
Step-by-step explanation:
If ABC is equilaterteral then all the angles must be equal and 60°
8x - 44 = 60 add 44 to both sides
8x = 104 divide both sides by 8
x = 13

Answer:
The Amount of tax paid on the cell phone is $11.9
Step-by-step explanation:
Given as :
The cost of the cell phone = x = $170
The tax rate of the cell phone = r = 7% of the phone cost
Let The Amount of tax paid on the cell phone = $y
<u>Now, According to question</u>
The Amount of tax paid on the cell phone = 7 % of cost of the cell phone
i.e y = 7% of x
Or, y =
× x
Or, y =
× $170
Or, y = 
∴ y = 7 × 1.7
i.e y = $11.9
So,The Amount of tax paid on the cell phone = y = $11.9
Hence, The Amount of tax paid on the cell phone is $11.9 Answer
We have to use the Distributive Property in this equation.
By the Distributive Property,

becomes

Now we need to isolate x. Remember PEMDAS?


Simplify the right side.
