X = -10.5

5-2(x+6)=14

Reorder the terms in parentheses
5+(-2x-12)=14

Remove unnecessary parentheses
+5-2x-12=+14

Move all terms containing x to the left and all other terms to the right.
-2x=+14-5+12

Simplify left and right side of the equation.
-2x=+21

Divide both sides of the equation by -2 to get x.

x=-10.5

Answer:

The value of <em> </em> $\frac{14}{8} + \frac{15}{12}$ = 3

Step-by-step explanation:

<u><em>Explanation</em></u>

<em>Given </em> $\frac{14}{8} + \frac{15}{12}$ <em></em>

<em></em>

<em>L.C.M 8 , 12 is 24</em>

<em> </em>

<em> </em> $\frac{14}{8} + \frac{15}{12} = \frac{14 X 3 + 15 X 2}{24}$ <em></em>

<em> = </em> $\frac{42 +30}{24} = \frac{72}{24} = 3$ <em></em>

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

The value of <em> </em> $\frac{14}{8} + \frac{15}{12}$ = 3

A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days). Assume that the number o

OLga [1]

We have that the graph will have a solution that is mathematically given as

y=12sin(6t-\pi)+2

<h3>Daylight time June trough to December</h3>

Question Parameters:

A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days).

Generally the equation for the Amplitude and vertical shift is mathematically given as

$A=\frac{Max+min}{2}\\\\A=\frac{10+14}{2}$

A=2

vertical shift = $\frac{Max-min}{2}$

vertical shift = $\frac{14-10}{2}$

vertical shift =1

Therefore, the time is given as

$t=\frac{2\pi}{b}$

Where

$b=\pi/6\\\\t=\frac{2\pi}{\pi/6}$

Hence,The graph will have a solution

y=12sin(6t-\pi)+2

Answer:

x = -6

Step-by-step explanation:

let's call the number x.

"five less than"

[expression] - 5

"the quotient of a number and 3"

x/3

x/3 - 5

"is -7"

x/3 - 5 = -7

<em>add 5 to both sides of the equation</em>

x/3 - 5 + 5 = -7 + 5

x/3 = -2

<em>multiply both sides of the equation by 3</em>

x/3 * 3 = -2 * 3

x = -6
