35 years
1year=365 days, 35/4= 11.xx. Since its under 36, add 11 days because of the leap year every 4 years. (35x365)+11.
=12786. Now since these are the total days, divide it by 3 since 8hours/24 hours is 1/3. And you get 4262 hours of sleep in her 35 years of life.

8*365= 2920
2920*35= 102200
102200/24= approx. 4,258.33 days

For this case we have the following equation:

$\frac {5} {6} (2x + 12) -8 = 4- (x + 1)$

We apply distributive property on the left side of the equation:

$\frac {5 * 2} {6} x + \frac {5 * 12} {6} -8 = 4- (x + 1)\\\frac {10} {6} x + \frac {60} {6} -8 = 4- (x + 1)$

We simplify the left side of the equation:

$\frac {5} {3} x + 10-8 = 4- (x + 1)$

Different signs are subtracted and the major sign is placed.

$\frac {5} {3} x + 2 = 4- (x + 1)$

On the right side we must take into account that:

$- * + = -$

So:

$\frac {5} {3} x + 2 = 4-x-1\\\frac {5} {3} x + 2 = 3-x$

We add x to both sides of the equation:

$\frac {5} {3} x + x + 2 = 3\\\frac {5 * 1 + 3 * 1} {3} x + 2 = 3\\\frac {5 + 3} {3} x + 2 = 3\\\frac {8} {3} x + 2 = 3$

We subtract 2 from both sides of the equation:

$\frac {8} {3} x = 3-2\\\frac {8} {3} x = 1$

We multiply by 3 on both sides of the equation:

$8x = 3$

We divide by 8 on both sides of the equation:

$x = \frac {3} {8}$

Thus, the solution of the equation is:

$x = \frac {3} {8}$

Answer:

$x = \frac {3} {8}$

Denis examined the records of the clients who had joined his gym more than six months ago, and he found these statistics: \begin

drek231 [11]

Answer:

Step-by-step explanation:

This is a conditional probability question. So it's asking you to find the probability that a client remained a member for more than 6 months, given that the client joined in January - which is formatted as P = (.5 | .12). You would then divide the chance of being over 6 months AND in January over the chance of being a member for over six months. ( .024 / .12) There, you would get .2 as your answer.

Answer:

9 sheep and 5 goats

Step-by-step explanation:

s + g = 14

125s + 75g = 1500

125( 14 - g ) + 75g = 1500

1750 - 125 g + 75g = 1500

50g = 250

g = 5 goats

s = 9 sheep

What is 5-6x=2+7x step by step?

HACTEHA [7]

The first thing you do is subtract 2 from both sides to move the 2 to the left side
3-6x=7x
now add 6x to both sides to move -6x to the right
3=13x
divide by 13 to eliminate the 13 on the right side
