*brainliest for best answer thank you* Solve for b.

vekshin1

Hello from MrBillDoesMath!

Answer:

The fourth choice, b = +\- sqrt( sg + a^2)

Discussion:

s = (b^2 - a^2)/g => multiply both sides by "g"

sg = b^2 - a^2 => add a^2 to both sides

sg + a^2 = b^2 => take the square root of each side

b = +\- sqrt( sg + a^2)

which is the fourth choice.

Thank you,

MrB

Which of the following is not a way to represent the solution of the inequality 2(x − 1) greater than or equal to −12?

lesya [120]

Let us solve the inequality first

$2(x-1)\ge -12$

Dividing through by 2 gives

$(x-1)\ge -6$

Grouping like terms gives

$x\ge -6+1$

This implies that;

$x\ge -5$

This corresponds to option A in words

If we rewrite as

$-5\le x$

it will correspond to option C in words

Representing on diagram corresponds to option D (See attachment)

All are correct ways to represent the solution except B.

The correct answer is option B

On easter morning 20 eggs were hidden kyla found 1/2 of them kevin found 1/4 of them what fraction of eggs were left to find

kotykmax [81]

$\frac{1}{2}*20= 10 
$ and $\frac{1}{4}*20= 5$
This means that Kayle found 10 eggs while Kevin found 5 eggs.
so 20-(10+5)= 5 eggs left.
To find the fraction, divide the number of eggs left over the number of total eggs.
$Fraction= \frac{5}{20}= \frac{1}{4}$

Hope this helps!
