Solving for variables is easy as all we must do is isolate the variable and simplify. In this case, to isolate the variable, we simply need to divide "n" by 10 (because the "n" is being multiplied by 10).
10n=40
/10 /10
n=4
Using the math above, we can see that n=4.
Answer:
5 cm
Step-by-step explanation:
Since 1 inch is 2.5 cm, you'll haft to double that. Making the answer 5 cm.
When x=9 the expression is undefined.
That is because any number over 0 is undefined, including 0/0.
7(72) + 0.10(2574) = 504 + 257.40 = 761.40 <== this is how much she will earn. Your gonna have to pick the answer choice that is the closest since no answer choices were given.
D. 54° as you know an external angle has to equal up to 360
when you start plugging in 360 by 36 gives you 10
360 by 40 gives you 9
360 by 45 gives you 8
360 by 54 gives you 6.666 repeating you know that it isn't possible
you cannot have a repeating number of sides as an angle measure
that's how you get that answer
