M = 5 and x = 4
3(5) - 2(4)
15 - 8 = 7
I hope this helps!
Answer:
Step-by-step explanation:
formula to find the sum of interior angle of a regular pentagon is
(n-2)*180 degree
here n means no of sides .since pentagon has 5 sides replace it by 5
=(5-2)*180
=3*180
=540 degree
The 11/2 cup of black beans is extraneous info, you just need to know that it provides 15% of the potassium you need daily. With that info, you know that you need 85% more to fulfill your daily value. If we say x is the total amount of potassium needed, then we can set up the equation:
x * 0.85 = 2890
Then we can solve for x by dividing both sides by 0.85. The answer, then, is 2890/0.85 = 3400 mg.
Which of the following is the simplified form of [1] fifth root of x times the [2] fifth root of x times [3] the fifth root of x times [4] the fifth root of x?
That's
![( \sqrt[5] x)^4 = x^{\frac 4 5}](https://tex.z-dn.net/?f=%20%28%20%5Csqrt%5B5%5D%20x%29%5E4%20%3D%20x%5E%7B%5Cfrac%204%205%7D)
That looks like the second choice.
