There are 10 kids that want ice cream. Each one can choose between chocolate, vanilla or strawberry. You'll collect their choice
1 answer:
Answer: There are 30 possible orders that can be made.
Step-by-step explanation:
Given : Number of kids that want ice cream= 10
Choices for flavors : chocolate, vanilla or strawberry.
i.e. Number of choices for flavors = 3
Then by Fundamental principle of counting , the number of possible orders can be =(Number of kids ) x (Choices for flavors)
Therefore , the total number of possible orders that can be made = 30.

Answer:
The ordered pair is indeed a solution to the system:
.
Step-by-step explanation:
Consider a system of equations about variables and
. An ordered pair
(where
and
are constant) is a solution to that system if and only if all equations in that system hold after substituting in
and
.
For the system in this question, would be a solution only if both equations in the system hold after replacing all
in equations of the system with
and all
with
.
The of the equation
would become
. The
of that equation would become
. The two sides are indeed equal.
Similarly, the of the equation
would become
. The
of that equation would become
. The two sides are indeed equal.
Thus, and
simultaneously satisfy both equations of the given system. Therefore, the ordered pair
would indeed be a solution to that system.
We need to solve for x, we need to get x alone
Lets start by removing -5
Add 5 on both sides
Now to isolate x , we need to remove the square from x
To remove square , take square root on both sides
square and square root will get cancelled
So and
