6/27 bc (6/27)=(8/36)= 216/216= they are the same or 2/9=6/27=8/36
Answer:
84°
Step-by-step explanation:
Let the measures of the triangle be 5x, 7x, 3x.
By interior angle sum postulate of a triangle.
5x + 7x + 3x = 180°
15x = 180°
x = 180°/15
x = 12°
7x = 7*12°= 84°
Measure of the largest angle = 84°
Using the conversion of exponent to power, the equivalent expression is given as follows:
![\frac{\sqrt{x}}{\sqrt[4]{y}z^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7Bx%7D%7D%7B%5Csqrt%5B4%5D%7By%7Dz%5E2%7D)
<h3>How to transform an exponent to a power?</h3>
It happens according to the following rule, with the denominator as the root and the numerator as the exponent:
![a^{\frac{n}{m}} = \sqrt[m]{a^n}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bn%7D%7Bm%7D%7D%20%3D%20%5Csqrt%5Bm%5D%7Ba%5En%7D)
In this problem, we are given the following expression:
Negative exponents go to the denominator, hence the <em>equivalent expression</em> is given by:

Answer:
11 Hours
Step-by-step explanation:
Let's say Lisa makes x hours babysitting and y hours giving music lessons.
Because she worked a total of 18 hours, we know that x + y = 18.
5 * x is how much money she earns babysitting for x hours, while 12 * y is how much money she earns giving music lessons for y hours. Adding them up gives her total revenue:
5x + 12y = 139
We now have a system of equations. Let's multiply both sides of x + y = 18 by 12:
12 * (x + y) = 18 * 12
12x + 12y = 216
Now, subtract 5x + 12y = 139 from 12x + 12y = 216:
12x + 12y = 216
- 5x + 12y = 139
_________________
7x + 0y = 77
Divide both sides by 7:
x = 11
Thus, Lisa spent 11 hours babysitting.
