Answer:

\left \{ {{x=2} \atop {y=2}} \right.

Step-by-step explanation:

Substitute the second equation into the first one:

4x+(2x-2)=10\\6x-2=10\\6x=12\\x=2

Substitute x=2 into the second equation:

y=2\times 2-2\\y=4-2\\y=2

\therefore \left \{ {{x=2} \atop {y=2}} \right.

as a contractor to make a hole 4 5/8 inches diameter. express the mixed number as an improper fraction.
san4es73 [151]

The mixed number as an improper fraction is 37/8

<h3>How to express the mixed number as an improper fraction?</h3>

The diameter is give as:

Diameter = 4 5/8

Next we convert the above number to an improper fraction

The numerator is calculated as

Numerator = 8 * 4 + 5

This gives

Numerator = 37

Hence, the mixed number as an improper fraction is 37/8

A students work to simplify a radical is shown below. Select the statemmebt which best applies to rhe sample mathematical work
Alik [6]

Answer:

D. The work shown above is correct, and y^5\sqrt[4]{y^3} may not be simplified further.

Step-by-step explanation:

If you add all the exponents of y in first line then we get

4+4+4+4+4+3=23

Which is same as the exponent in original problem.

So first line is good.

Since it is 4th root so each y^4 will turn into y when it moves out of the radical so final answer is correct.

Hence correct choice is "D. The work shown above is correct, and y^5\sqrt[4]{y^3} may not be simplified further." is the correct answer.
