15x = 500-50
15x = 450
x = 450/15
x =30
Thus, x is equal to 30.

Charlie is at a small airfield watching for the approach of a small plane with engine trouble. He sees the plane at an angle of

Lera25 [3.4K]

Check the picture.

Let the given points represent the following:

F : Charlie's feet
E: Charlie's eyes
P: location of the plane
G: the foot of the perpendicular drawn from P to the ground
A: a point on PG, such that |GA|=|FE|=5.2 feet.

Clearly EAP is a right triangle, with m(AEP)=32°, side PA=1,700-5.2=1694.8 feet.

the ground distance from Charlie to the plane is |FG|=|EA|

from right angle trigonometry, we know that:

 $tan32= \frac{PA}{AE}$

 $0.625= \frac{1694.8}{AE}$

 $AE= \frac{1694.8}{0.625}=2711.68$ feet


Answer: 2711.68 feet

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. Note that PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

& is the order of operation.

Also note, that you are solving for x, in all instances.

1) x + c = d

Note the equal sign, subtract c from both sides:

x + c (-c) = d (-c)

x = d - c

2) x - p = g

Note the equal sign, add p to both sides:

x - p (+p) = g (+p)

x = g + p

3) FX = S

Note the equal sign, divide F from both sides:

(FX)/F = (S)/F

X = S/F

4) 3x - q = p

Note the equal sign, first, add q to both sides:

3x - q (+q) = p (+q)

3x = p + q

Next, divide 3 from both sides. Note that when you divide 3 from the right side, you are dividing from all terms:

(3x)/3 = (p + q)/3

x = (p + q)/3

5) cx - d = 4

Note the equal sign, first, add d to both sides:

cx - d (+d) = 4 (+d)

cx = 4 + d

Next, divide c from both sides.

(cx)/c = (4 + d)/c

x = (d + 4)/c

6) FX - S = M

Isolate the variable, x. First, add S to both sides:

FX - S (+S) = M (+S)

FX = M + S

Next, divide F from both sides:

(FX)/F = (M + S)/F

X = (M + S)/F

-6x + 3 ≥ 21

Subtract 3 from both sides.

-6x ≥ 21 - 3

Simplify.

-6x ≥ 18

Divide both sides by -6.

Remember, when dividing or multiplying by a negative number, you must switch the signs.

x ≤ 18 / -6

Simplify.

x ≤ -3

So, your answer is D) x ≤ -3

Simplify 5(81/3 + 241/3)1/4

madreJ [45]

Answer:

$214\frac{2}{3}$

Step-by-step explanation:

$8\bigg(\frac{81}{3}+\frac{241}{3}\bigg)\frac{1}{4} \\\\= 8\bigg(\frac{81+241}{3}\bigg)\frac{1}{4} \\\\= 8\bigg(\frac{322}{3}\bigg)\frac{1}{4} \\\\= 8\times\frac{322}{3}\times\frac{1}{4} \\\\= 2\times\frac{322}{3}} \\\\= \frac{644}{3}} \\\\= 214\frac{2}{3} \\$
