Please solve this question asap

disa [49]

Step-by-step explanation:

$y = \sqrt{4x + 6}$

${y}^{2} = 4x + 6$

${y}^{2} - 6 = 4x$

$\frac{1}{4} ( {y}^{2} - 6) = x$

Swap x and y

$\frac{ {x}^{2} - 6 }{4} = y$

80% of what number is 64

Thepotemich [5.8K]

Make an equation.

80% = 0.8

'of' is multiplication

'what number' is 'x'

'is' is an equal sign

0.8 * x = 64

0.8x = 64

Divide 0.8 to both sides:

x = 80

The mean of five numbers is 8. when another number is added the mean is 7. find the number added

sasho [114]

Answer:

$\large \boxed{\sf \ \ 2 \ \ }$

Step-by-step explanation:

Hello,

<u>The mean of five numbers is 8</u> so we can write

$\dfrac{x_1+x_2+x_3+x_4+x_5}{5}=8$

<u>When another number is added the mean is 7</u>, let s note x the another number we can write

$\dfrac{x_1+x_2+x_3+x_4+x_5+x}{6}=7$

From the first equation we can say

$x_1+x_2+x_3+x_4+x_5=8*5=40$

So the second equation becomes

$\dfrac{x_1+x_2+x_3+x_4+x_5+x}{6}=7\\\\ \dfrac{40+x}{6}=7\\\\40 + x = 6*7=42\\\\ x = 42-40 = 2\\$

The solution is then 2

Hope this helps
