Solve 2-6(1-x)=6-4(-x-2) for x
OLEGan [10]

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

Which expression is equivalent to ^3 square root 64a^6 b^7 c^9
sergij07 [2.7K]

Answer:

4a^{2} b^{2} c^{3} (\sqrt[3]{b})

Step-by-step explanation:

The given expression is :

\sqrt[3]{(64}a^{6}b^{7} c^{9} )

Writing 64 ,a,b,c as cubes we have:

= \sqrt[3]{(}4^{3}( a^{2})^3( b^{2})^3.b( c^{3} )^3)

Using radical rule we have :

=4a^{2} b^{2} c^{3} (\sqrt[3]{b}).

The second option is the right answer.

W usng a calculator, paper and pencil, or mental math.
Paraphin [41]

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 = \frac{18\times 15}{4}=67.5 mins

Hence time required by Mandy to complete 15 km race is 67.5 mins.
