Answer:
Her heart beats 75 times per minute.
Step-by-step explanation:
Okay, for this one, I recommend setting up a proportion table. First you will figure out that her heart beats 225 times approximately in 3 minutes (no duh), and literally all you have to do is divide 225 by 3. That's all! Then you'll get 75! I hope this helped you!
Answer:
Solution
=
−
1
so x=-1

dont ever forget to simplify or the answer will be inncorrect ! :0 gooluck with school hope i helped
Answer:
Step-by-step explanation:
<u>9</u>/14 × 5/<u>3</u>
The factors can be canceled if they are factors of both the numerator of the first fraction and the denominator of the second fraction. The factors get cancelled leaving the second fraction to a whole number.
3/14 × 5
(3 × 5)/14
15/14
x + y = 3 -------------- i x2
2x - √3y = 5 ---------ii x1
Subtracting eq ii from i
2x + 2y = 6
- 2x - √3y = 5
-------------------------
2+ √3y = 1
y = 1/ 2+√3
= 2- √3y

When dealing with radicals and exponents, one must realize that fractional exponents deals directly with radicals. In that sense, sqrt(x) = x^1/2
Now, how to go about doing this:
In a fractional exponent, the numerator represents the actual exponent of the number. So, for x^2/3, the x is being squared.
For the denominator, that deals with the radical. The index, to be exact. The index describes what KIND of radical (or root) is being taken: square, cube, fourth, fifth, and so on. So, for our example x^2/3, x is squared, and that quantity is under a cube root (or a radical with a 3). Here are some more examples to help you understand a bit more:
x^6/5 = Fifth root of x^6
x^3/1 = x^3
^^^Exponential fractions still follow the same rules of simplifying, so...
x^2/4 = x^1/2 = sqrt(x)
Hope this helps!
