Answer:
Step-by-step explanation:
The equation to solve for "a" is:
The first step is to convert all of them to same bases.
9, 81, and 27, all can be expressed in base 3, lets do this:
We can use the property: to simplify further:
The right side has 2 same bases multiplied, we can simplify this using the property:
Thus, we have:
Now, both sides have same base, so exponents would be equal. Now lets equate and solve for "a":
So,
a = -4
This is not an equation because it lacks an equal sign....so the only thing we can do here is combine like terms.
4 - 2x - 12 - 2x + 1 =
-4x - 7
Answer:
Step-by-step explanation:
- Hoodies bought = x
- Shoes bought = y
- Sum = 250
- The cost difference 4 times
Let hoodies cost be k, then pit of shoes cost 4k
Equation to reflect the shopping scenario
Answer:
r = 2 units
h= 36 units
Step-by-step explanation:
Given That:
Cones A and B both have volume cubic 48π units
The volume of a cone =
So for cone A
Volume for cone B
Due to different dimensions;
Cone A has
radius = 6 units
height = 4 units
To determine the one possible radius and height for cone B;
we have
Therefore; the only possible way for this equation is :
If we are to check: we will realize that;
Therefore, the possible radius for the cone B = 2 units and height = 36 units. Hence from the question, we are told they both have the same volume of 48 π units.
