Answer:

Step-by-step explanation:
You can see the attached picture
If О is the center of a circle then:
<span>
OA = OB = OC = OD [radii]
AB = AH + HB = 15 + 15 = 30 </span>⇒ AB = CD
<span>
So </span>ΔAOB ≅ ΔCOD [SSS rule] ⇒ x = OH = 16 units.
Answer:
f = 100 + 0.133d
Step-by-step explanation:
For each trip, they charge an initial fee of 100 in addition to a constant fee for each vertical meter climbed.
For example, for 3000 meters of climbing, they charged the additional constant fee of 400.
Therefore, per meter climbing they charges
.
Therefore, if f represents the fee in dollars of a trip they climbed d vertical meters then we can model the situation as
f = 100 + 0.133d (Answer)
Answer:
x = -3
Step-by-step explanation:
3x + 2 = x + 4(x + 2)
Get rid of the parentheses by using distribution
4 * x = 4x
4 * 2 = 8
3x + 2 = x + 4x + 8
Combine like terms
x + 4x = 5x
3x + 2 = 5x + 8
Isolate the x
3x + 2 = 5x + 8
-2 -2
3x = 5x + 6
-5x -5x
-2x = 6
Now, simplify it
-2x = 6
---- -----
-2 -2
x = -3
