Answer:
x = 18.
Step-by-step explanation:
x / 1.2 = 15
To isolate x we multiply both sides of ther equation by 1.2:
x = 15 * 1.2
x = 18 (answer).
Answer:
3/4
Step-by-step explanation:
The distance between the ship and the light house is 139.28 km.
Solution:
The given image shows, it is right triangle.
Height = 50 km
Base = 130 km
Hypotenuse = ?
Using Pythagoras theorem,
<em>In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.</em>



Taking square root on both sides, we get
Hypotenuse = 
Hypotenuse = 139.28 km
The distance between the ship and the light house is 139.28 km.
Answer:
11, 15
Step-by-step explanation:
They both occur two times so they are tied for mode so both numbers is the answer
Answer:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
Step-by-step explanation:
For this case we assume the following equation:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
