Answer:

The operation that will cancel out division is multiplication.

Step-by-step explanation:

For example:

$\frac{2+5x}{2} \\$

*in order to solve for x, and get the upper equation without division, you must multiply by the negative reciprocal*

$2*(\frac{2+5x}2} )$

$4+10x\\$

*to get x alone, we must subtract 4 from both sides*

$10x = -4\\\\-4 / 10 = - 2/5$

$x=- 2/5$

Answer:

(a) Output = 37

(b) Input = 9

Step-by-step explanation:

Given

$y =x5 - 3$

Solving (a): Output, when input = 8

This means that, we solve for y when x = 8

So, we have:

$y =x5 - 3$

$y =8*5 - 3$

$y =40 - 3$

$y = 37$

Solving (b): Input, when output = 42

This means that, we solve for x when y = 42

So, we have:

$y =x5 - 3$

$42 = x5 - 3$

Collect like terms

$x5 = 42 + 3$

$x5 = 45$

Divide both sides by 5

$x = 9$

How could you find an even better estimate of the square root of 2

vodomira [7]

Answer:

First of all you need to know the $\sqrt {4}$ it's equal to 2 and

$\sqrt {1}$ which is the number is between 1 and 2 and between that number there maybe the possibilities of above 0.5 or under 0.5

After that Figure out which one was bigger? $\sqrt {2}$ or $\sqrt {3}$ ? The answer is $\sqrt {3}$ and $\sqrt {3}$ also near to $\sqrt {4}$ so it should be above 0.5 .

So we know that $\sqrt {2}$ is between 1 and 1.5.

Hopes that information was help you a lot
