y = 35
Step-by-step explanation:
Answers would be x = -6 , x = -2/3
Answer:
4 + 2/3 hours
Step-by-step explanation:
For the expert,
6 hours = 1 job
For the secretary,
7 hours = 1 job
We want to figure out how much the expert gets done in 2 hours.
2 hours = x jobs for the expert.
To turn 6 hours = 1 job into this, we can multiply both sides of the equation by 2 (the number we want to get to) / 6 (the number we are at) to get
6 hours * 2/6 = 1 job * 2/6
2 hours = 2/6 jobs
Therefore, the expert does 2/6 of the job, and 1-2/6 = 4/6 of the job is left for the secretary. We want to figure out how long it takes for her to complete the job
We know
7 hours = 1 job
and want to figure out
y hours = 4/6 jobs
We can multiply both sides of the original equation by (4/7) (the number we want to get to) / 1 (the number we are at) to get
7 hours * 4/6 = 1 job * 4/6
28 /6 hours = 4/6 jobs
= 4 + 4/6 hours
= 4 + 2/3 hours

Step-by-step explanation:
(![\sqrt[3]{x^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B2%7D%20%7D)
× ![\sqrt[6]{x^{4}}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7Bx%5E%7B4%7D%7D)
)⁻³
is the same thing as 
you can think of the numerator as the power and the denominator as the root
rewrite both terms:
( × 
)⁻³
simplify the 4/6:
( × )⁻³
bases are the same, add the exponents:
(
)⁻³
multiply the exponents:
simplify:
x⁻⁴
