Nine over negative six is three times the five gives me fifth teen and six over negative three gives me three so therefore they are not the same but 15+9=24

5x +9/-6=3x+6/-3 Note: you have to get rid of one of the numbers with variables 2x +9/6=6/-3 ×6. ×6 ____________ 2x+9=36/-3 -9. -9 ___________ 2x = 36/-12 Note: divide 36 and negative 12 2x = -3 ÷2. ÷2 ________ X= -3/2

Step-by-step explanation:

$third \: term = ( \frac{1}{2} \times coefficient\: of \:x)^{2} \\ \\ = ( \frac{1}{2} \times \frac{ - 2}{7} )^{2} \\ \\ = ( \frac{ - 1}{7} )^{2} \\ \\ = \frac{1}{49}$

So, you need to add $\frac{1}{49}$ on both sides of the quadratic equation.

In a thunderstorm, the wind velocity in meters per second can be described by the function v(p) = 5.7 √998 - p, where p is the a

Answer:

923.1927 millibars

Step-by-step explanation:

The wind velocity is given by the function:

$v(p)=5.7\sqrt{(998-p}$

#We make p the subject of the formula:

$v(p)=5.7\sqrt{(998-p}\\\\v=5.7\sqrt{(998-p}\\\\\frac{v}{5.7}=\sqrt{(998-p}\\\\\frac{v^2}{5.7^2}=998-p\\\\p=998-\frac{v^2}{5.7^2}$

#Substitute the given values in the function above to solve for p;

$p=998-\frac{v^2}{5.7^2}\\\\=998-\frac{49.3^2}{5.7^2}\\\\=923.1927\ millibars$

Hence, the air pressure is 923.1927 millibars.

The time it takes runners to complete a certain marathon are normally distributed with a mean of 4.6 hours and a standard deviat

Yuki888 [10]

The time for this z-score is 3.28.

The formula for z-scores is

z = (X-μ)/σ

Using our information, we have

-1.2 = (X-4.6)/1.1

Multiply both sides by 1.1:
-1.2(1.1) = X - 4.6
-1.32 = X - 4.6

Add 4.6 to both sides:
-1.32 + 4.6 = X - 4.6 + 4.6
3.28 = X

You have 88 love hearts and decide to share them with your friend . For every 5 love hearts you keep ,you give 3 to your friend

aliya0001 [1]

You keep 5, and give 3 away: 5 +3 = 8

88 hearts / 8 = 11

11 *3 = 33 hearts given away
