÷ by the amount of numbers
45÷5=9
Ansser: mean=9
So if p then q
the converse is if q then p
so
if x is odd then 2x+1 is odd
converse is
if 2x+1 is odd, then x is odd
4th option
Alright my friend so if she ran 1/4 a mile in just 3 minutes then her overall time will be 12 minutes because she still has 3 more to go so basically it'll be 3 x 4 = 12
Answer:

Step-by-step explanation:
+6x-5=0
we divide the coefficient of the X by half :
in this case: 6/2 = 3 , then we do the following
The result obtained is raised to square power: 3^2=9
we sum and subtract by 9 to maintain the balance of the equation:
+6x+9-9-5=0
we have:
-9-5=0
= 14
lets apply square root on both sides of the equation:

we know:

so we have:
abs(x+3)=
from where two solutions are obtained

finally we have:

Let's call the distance from the beach to the playground x.
Let's call the distance from the stand to the parking lot z.
Let's call the base of the biggest triangle in the picture (from the parking lot to the left) y.
Recall the pythagorean theorem: the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.
There are three right triangles we can work with.
Triangle with sides 48, x and z. Here z is the hypotenuse so we get the equation

Triangle with sides 27, x and y. Here y is the hypotenuse so we get

Triangle with sides z, y and (48+27). Here (48+27) is the hypotenuse so we get

. That is,

We have 3 equations and 3 unknowns (x, y and z). So let's take the last equation:

and replace

and

using expressions that contain an expression in terms of x from the first two equations we came up with.
That gives us:

which we solve for x as follows:

Now that we know x we can substitute 36 for x into the equation

and solve for z as follows:

This means that the distance from the beach to the parking lot is 36 m and the distance from the stand to the parking lot is 60 m.
