(x^-3)^ -5x^6=x^(-3· -5x^6)=x^15x^6
The solution is
We group like terms, to obtain;
Simplify to get,
We further simplify to get;
This can also be rewritten as;
Or
![(-\infty 3] \cup (18,+ \infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%203%5D%20%5Ccup%20%2818%2C%2B%20%5Cinfty%29)
This can be represented on the number line as shown in the diagram.
Colin gets 3/10 , emma and dave 7/10 (ratio 3:2) %287%2F10%29%2F5+=+7%2F50%29
emma 21/50 and Dave 14/50 0r 7/25 of the money
There different bcuz the denominator is the bottom number when u multiply or divide a fraction when u find a common number out of the 2 bottom ones
there alike bcuz they both r numbers in common with the number u r working with.
Answer: Money required to save in 3 weeks =490–175 =315
Let y represent the money to be saved and x represent the money to be saved per week
Then x = y/3 or 3x = y is the equation
