Plz help need step by step

Ratling [72]

Answer: X would equal -8

Step-by-step explanation: Starting off, you would cross multiply, so 414 times 1 = (x-10) times -23. It's similar to the one I answered before, just with different numbers. 414 = -23 (x-10). After that, distribute to get: 414 = -23x +230. Then subtract 230 from both sides and divide by -23 to get x. Hope that helps.

Work out the area of this semicircle.Take pie to be 3.142 and give your answer to 2 decimal places 10cm

rosijanka [135]

Answer:

The area of the semi circle $A = 157.1 cm^2$

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<em>Given radius of circle 'r' = 10 cm</em>

<em>The area of the circle formula </em>

<em> </em> $A = \pi (r)^{2}$ <em></em>

<em>The area of the semi circle formula </em>

$A = \frac{\pi (r)^{2} }{2}$

taking π =3.142

$A = 3.142 X \frac{(10)^2}{2}$

On calculation , we get

$A = 157.1 cm^2$

<u><em>Final answer</em></u>:-

<em>The area of the semi circle </em> $A = 157.1 cm^2$ <em></em>

Solution to the inequality 16x−33x<37x+27.

astra-53 [7]

<em><u>The solution to the inequality is:</u></em>

$x>\frac{-1}{2}$

<em><u>Solution:</u></em>

Given inequality is:

$16x-33x$

We have to find the solution to given inequality

$\mathrm{Add\:similar\:elements:}\:16x-33x=-17x$

$-17x$

$\mathrm{Subtract\:}37x\mathrm{\:from\:both\:sides}$

$-17x-37x$

Simplify the above inequality

$-54x$

$\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}$

Remember that, change the inequality sign if you divide or multiply both sides by a negative number

If you divide or multiply both sides by a positive number,the inequality sign will not change

$\left(-54x\right)\left(-1\right)>27\left(-1\right)\\\\54x>-27$

$\mathrm{Divide\:both\:sides\:by\:}54$

$\frac{54x}{54}>\frac{-27}{54}\\\\x>-\frac{1}{2}$

Thus the solution to inequality is found
