Answer:
x = 9
Step-by-step explanation:
Simplifying
2 + -6(1 + -1x) = 6 + -4(-1x + -2)
2 + (1 * -6 + -1x * -6) = 6 + -4(-1x + -2)
2 + (-6 + 6x) = 6 + -4(-1x + -2)
Combine like terms: 2 + -6 = -4
-4 + 6x = 6 + -4(-1x + -2)
Reorder the terms:
-4 + 6x = 6 + -4(-2 + -1x)
-4 + 6x = 6 + (-2 * -4 + -1x * -4)
-4 + 6x = 6 + (8 + 4x)
Combine like terms: 6 + 8 = 14
-4 + 6x = 14 + 4x
Solving
-4 + 6x = 14 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
-4 + 6x + -4x = 14 + 4x + -4x
Combine like terms: 6x + -4x = 2x
-4 + 2x = 14 + 4x + -4x
Combine like terms: 4x + -4x = 0
-4 + 2x = 14 + 0
-4 + 2x = 14
Add '4' to each side of the equation.
-4 + 4 + 2x = 14 + 4
Combine like terms: -4 + 4 = 0
0 + 2x = 14 + 4
2x = 14 + 4
Combine like terms: 14 + 4 = 18
2x = 18
Divide each side by '2'.
x = 9
Simplifying
x = 9
Answer:
![4a^{2} b^{2} c^{3} (\sqrt[3]{b})](https://tex.z-dn.net/?f=4a%5E%7B2%7D%20b%5E%7B2%7D%20c%5E%7B3%7D%20%28%5Csqrt%5B3%5D%7Bb%7D%29)
Step-by-step explanation:
The given expression is :
![\sqrt[3]{(64}a^{6}b^{7} c^{9} )](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%2864%7Da%5E%7B6%7Db%5E%7B7%7D%20c%5E%7B9%7D%20%29)
Writing 64 ,a,b,c as cubes we have:
= ![\sqrt[3]{(}4^{3}( a^{2})^3( b^{2})^3.b( c^{3} )^3)](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%28%7D4%5E%7B3%7D%28%20a%5E%7B2%7D%29%5E3%28%20b%5E%7B2%7D%29%5E3.b%28%20c%5E%7B3%7D%20%29%5E3%29)
Using radical rule we have :
=.
The second option is the right answer.
Answer:
Mandy will take 67.5 mins to complete the 15 km race.
Step-by-step explanation:
Given:
Mandy runs 4 km in 18 min
She plans to run in a 15 km race.
We need to find how much time required to run 15 km.
4 km =18 min
15 km = time required for 15 km race
By Using Unitary method we get,
Time required for 15 km = 
Hence time required by Mandy to complete 15 km race is 67.5 mins.
