Answer: The two equations that represent the conditions in the problems are 
Step-by-step explanation:
Since we have given that
Cost of 3 sparrows = $1
Cost of 2 turtle doves = $1
Cost of 1 dove = $2
Number of birds = 30
total cost = $30
So, Cost of s sparrows would be
Cost of t turtle doves would be
Cost of d doves would be
According to question, it becomes,
and
Hence, the two equations that represent the conditions in the problems are
The answer is 6 inches, 3*3*3 equals 27, the current volume of the cube, 27*8 equals 216, the new volume, 6*6*6 equals 216, so the side lengths equal 6 inches.
First of all, ur not stupid, ur brain is just tired.

50 + (15 × 15), 50 + 15 × 50 + 15, (10 × 5) + 225, 10 × 225 + 5 × 225
Solution:
Given expression is 50 + 225.
To find the equivalent expressions for 50 + 225.
(1) 225 can be written as 15 × 15.
⇒ 50 + 225 = 50 + (15 × 15)
(2) Using distributive law, we find the another equivalent expression
a + (b × c) = a + b × b + c
⇒ 50 + (15 × 15) = 50 + 15 × 50 + 15
(3) Now, 50 can be written as 10 × 5.
⇒ 50 + 225 = (10 × 5) + 225
(4 Using distributive law, we find the another equivalent expression
a + (b × c) = a + b × b + c
⇒ (10 × 5) + 225 = 10 × 225 + 5 × 225
Hence the equivalent expressions for 50 + 225 are:
50 + (15 × 15)
50 + 15 × 50 + 15
(10 × 5) + 225
10 × 225 + 5 × 225

Answer:
![f^{-1}(x)=\dfrac{\sqrt[3]{x}+1}{2}}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Cdfrac%7B%5Csqrt%5B3%5D%7Bx%7D%2B1%7D%7B2%7D%7D)
Step-by-step explanation:
Interchange x and y in the function definition and solve for y.
![x=(2y-1)^3\\\\\sqrt[3]{x}=2y-1\qquad\text{take cube root}\\\\\sqrt[3]{x}+1=2y\qquad\text{add 1}\\\\y=\dfrac{\sqrt[3]{x}+1}{2}\qquad\text{divide by 2}\\\\\boxed{f^{-1}(x)=\dfrac{\sqrt[3]{x}+1}{2}}](https://tex.z-dn.net/?f=x%3D%282y-1%29%5E3%5C%5C%5C%5C%5Csqrt%5B3%5D%7Bx%7D%3D2y-1%5Cqquad%5Ctext%7Btake%20cube%20root%7D%5C%5C%5C%5C%5Csqrt%5B3%5D%7Bx%7D%2B1%3D2y%5Cqquad%5Ctext%7Badd%201%7D%5C%5C%5C%5Cy%3D%5Cdfrac%7B%5Csqrt%5B3%5D%7Bx%7D%2B1%7D%7B2%7D%5Cqquad%5Ctext%7Bdivide%20by%202%7D%5C%5C%5C%5C%5Cboxed%7Bf%5E%7B-1%7D%28x%29%3D%5Cdfrac%7B%5Csqrt%5B3%5D%7Bx%7D%2B1%7D%7B2%7D%7D)
