Answer: 9/10 of the book.
Step-by-step explanation:
1. Convert all of the fractions to have a common denominator. 6, 5, and 3 are all multiples of 30, so we can convert the fractions to 30ths.
1/6 = 5/30
2/5 = 12/30
1/3 = 10/30
2. Add the fractions together to find the whole amount of the book Joyce has read.
5/30 + 12/30 + 10/30 = 27/30
3. Simplify
27/30 -> 9/10
<span>19 − 6( − k − 2)
Distribute -6:
= 19 + 6k + 12
Combine like terms:
= 6k + 31
Answer: </span>6k + 31
Answer:
![f^{-1} (x)=\frac{x+6}{7}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%28x%29%3D%5Cfrac%7Bx%2B6%7D%7B7%7D)
Step-by-step explanation:
To find the inverse of a function, we must substitute in y for f(x), swap the locations of y and x, and then solve for y
![y=7x-6\\\\x=7y-6\\\\x+6=7y\\\\y=\frac{x+6}{7} \\\\f^{-1} (x)=\frac{x+6}{7}](https://tex.z-dn.net/?f=y%3D7x-6%5C%5C%5C%5Cx%3D7y-6%5C%5C%5C%5Cx%2B6%3D7y%5C%5C%5C%5Cy%3D%5Cfrac%7Bx%2B6%7D%7B7%7D%20%5C%5C%5C%5Cf%5E%7B-1%7D%20%28x%29%3D%5Cfrac%7Bx%2B6%7D%7B7%7D)
A)your equation for t-mobile would be
y=20x+100
Topar equation
y=30x
B) you’d set the two equation equal to each other
20x+100=30x
giving you the answer x=10
C) when x>13
D) when x<14
i’m a bit iffy on the last two but that’s the conclusion i came to
