Answer:

Step-by-step explanation:

2 times the first and –1 time the second will eliminate the x variables in the equations.

Option E is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an equation.

We have,

(1/3)x - (2/3)y = 7 ____(1)

(2/3)x + 3y = 11 _____(2)

Now,

Multiply 2 on equation (1).

Multiply - 1 on equation (2).

We get,

(2/3)x - (4/3)y = 14

-(2/3)x  - 3y = -11    

           -(4/3)y - 3y = 14 - 11

Now x variable gets eliminated.

Thus,

2 times the first and –1 time the second will eliminate the x variables in the equations.

   [tex](\frac{8^4}{10^4} )^{-\frac{1}{4} }[/tex]  = [tex]\frac{5}{4}[/tex]

Step-by-step explanation:

Explanation

Given  

       [tex](\frac{8^4}{10^4} )^{-\frac{1}{4} }[/tex]

By using algebra formulas

  [tex](\frac{a}{b} )^{m} = \frac{a^m}{b^n}[/tex]

[tex](\frac{8^4}{10^4} )^{-\frac{1}{4} } = \frac{(8^{4})^{\frac{-1}{4} } }{(10^{4} )^{\frac{-1}{4} } }[/tex]

[tex](a^{m} )^{n} = a^{mn}[/tex]

[tex]\frac{(8^{4})^{\frac{-1}{4} } }{(10^{4} )^{\frac{-1}{4} } } = \frac{8^{4X\frac{-1}{4} } }{10^{4 X\frac{-1}{4} } }[/tex]

          = [tex]\frac{8^{-1} }{10^{-1} }[/tex]

           [tex]= \frac{10}{8} \\= \frac{5}{4}[/tex]

Answer:

100/3 yards

Step-by-step explanation:

36 inches=1 yard, so 1200/36 will equal how many yards 1200 inches is.

Simplify:

1200/36

divide numerator and denominator by 12 and you get 100/3

100/3 yards

Tracey kicks the ball for 100/3 yards.

Given that, at soccer practice, Tracey's best kick travelled a distance of 1,200 inches.

We need to find out for how many yards did she kick the ball.

Inch-to-yard conversion explanation

So to convert from a value in inches to one in yards, we need to divide by 36. To convert a value in yards to inches, we need to multiply by 36.

Now, the number of yards =1200/36=100/3

Hence, Tracey kicks the ball for 100/3 yards.
