Lol, this is pretty simple (sorry if me saying simple makes you feel stupid, if it makes you feel any better I'm rlly stupid lol). Well just look at is normally as 8+8= which would equal 16 :) I really hope this helps.

The |x| operator means 'absolute value' or the positive value of the negative values. To help this make sense, here's a visual representation:
$|-8| = 8$

But,
$|8| = 8$

Do you see what I mean? BTW, your answer will just be 8 + 8 or 16.

Find the value of x.

nadya68 [22]

Answer:

127 degrees

Step-by-step explanation:

1. Find the angle next to "x" using the fact that all the angles in a triangle add to 180 degrees.

180-30-97 = 53

2. Angle X and the angle that is 53 degrees are supplementary meaning they will add to 180 degrees since it's on a line

180-53=57

Hope this helped :)

For altitudes up to 36,000 feet, the relationship between ground temperature and atmospheric

Verizon [17]

Answer:

The equation for a is $a=-\frac{2000}{7}*(t-g)$

The altitute is 101,428.57 feet

Step-by-step explanation:

You know that the relationship between ground temperature and atmospheric temperature can be described by the formula

t = -0.0035a +g

where:

t is the atmospheric temperature in degrees Fahrenheit
a is the altitude, in feet, at which the atmospheric temperature is measured
g is the ground temperature in degrees Fahrenheit.

Solving the equation for a:

-0.0035a +g=t

-0.0035a= t - g

$a=\frac{t-g}{-0.0035}$

$a=-\frac{2000}{7}*(t-g)$

<u><em>The equation for a is </em></u> $a=-\frac{2000}{7}*(t-g)$ <u><em></em></u>

If the atmospheric temperature is -305 °F and the ground temperature is 50 °F, then t= -305 °F and g= 50 °F

Replacing in the equation for a you get:

$a=-\frac{2000}{7}*(-305-50)$

$a=-\frac{2000}{7}*(-355)$

a= 101,428.57

<u><em>The altitute is 101,428.57 feet</em></u>

Find the midpoint of the segment with the following endpoints. (10, 7) and (5, 4)

KatRina [158]

Answer:

$\frac{15}{2} , \frac{11}{2}$

Step-by-step explanation:-

To find the midpoint, the equation we use is:-

$\frac{x1 +x2}{2} , \frac{y1 + y2}{2}$

x1 = 10

x2 = 5

y1 = 7

y2 = 4

Substituting the values in the equation, we get:-

$\frac{10+5}{2} , \frac{7+4}{2}$

Coordinates of the midpoint---> $\frac{15}{2} , \frac{11}{2}$

5(x+3)(x+2)-3(x2+2x+1)

mr Goodwill [35]

[ Answer ]

$\boxed{5x^{2} \ + \ 13x \ + \ 27}$

[ Explanation ]

Simplify: 5(x + 3)(x + 2) - 3(x2 + 2x + 1)

--------------------------------------

Add Similar Elements: 2x + 2x = 4x

5(x + 3)(x + 2) - 3(4x + 1)

Expand: 5(x + 3)(x + 2) - 3(4x + 1): $5x^{2}$ + 25x + 30

$5x^{2}$ + 25x + 30 - 3(4x + 1)

Expand: - 3(4x + 1): -12x - 3

$5x^{2}$ + 25x + 30 - 12x - 3

Simplify: $5x^{2}$ + 25x + 30 - 12x - 3: $5x^{2}$ + 13x + 27

= $5x^{2}$ + 13x + 27

$\boxed{[] \ Eclipsed \ []}$
