(100-9^2)/3

PEMDAS: parenthesis, exponents, multiply, divide, add, subtract

Lets' work on the parethesis first.

100-9^2

We can do the exponent first, 9^2=81, so 100-81=19

Then we divide and 19/3 is your final answer.

To amend U.S. Constitution, 3/4 of the 50 states must approve the amendment. If 35 states approve an amendment, will the Constit
Elodia [21]
To answer the question we need to know if 35 out of 50 states is equal or greater than 3/4 if that is the case, the Constitution will be ammended, and that is represented like this:
35/50 >= 3/4
that inequality is saying that 35 states out of 50 is equal or greater than 3/4, lets simplify and modify the fractions to compare easily:
<span>35/50 >= 3/4
</span>7/10 <span>>= 3/4
</span>now we need to find the least common multiplier of 10 and 4 to take the fractions to a common denominator and compare easy. Lets multiply numerator and denominator for a correct number to get the fractions to denominator common 20, the lcm:
7/10 <span>>= 3/4
</span>(2/2)(7/10) >= (5/5)(3/4)
2*7/2*10 >= 5*3/5*4
14/20 >= 15/20
we can see that the inequality does not hold, so,
<span>35/50 >= 3/4
</span>does not hold either, therefore the Constitution cannot be ammended

How can I solve for X?
Natali [406]
Since we know the angle 250 and a circle is 360 degrees we can solve for x by subtracting 250 from 360.

360-250=110 degrees. 

Tada!
