The required simplest form is:
Step-by-step explanation:
We have been given Kyle has 125 marbles.
And 50 out of total 125 are red and rest of them are other colours
that means other colour marble are 125-50=75
we need to find ratio of the number of red marbles to the total of marbles
The ratio is:
The required simplest form is:
Answer:
Step-by-step explanation:
2/5
Answer:
11²= 121
5³= 125
2⁷= 128
Step-by-step explanation:
The whole numbers can be multiplied with themselves to get numbers between 120 and 130 .
For example
11*11= 121
This can be written in the exponent form as
11²= 121 which is between 120 and 130.
Also
5*5*5= 125 or
5³= 125 which is also between 120 and 130.
and
2*2*2*2*2*2*2= 128
2⁷= 128 which is between 120 and 130 as required.
We see that as the powers or exponent increases the whole number is decreased.
1) The substitution method. This method is best utilized when one of the variables in one of the equations has a coefficient of 1 or -1, otherwise you will introduce fractions. Substitution can also be used for nonlinear systems of equations.
(2) Linear combinations also called the elimination method, multiplication and addition method, etc... My personal favorite as it can be done efficiently. It generalizes well to larger systems and is the underpinning of various other solution methods.
As the name implies it requires the equations to be linear.
You need to know both and be comfortable switching between them.
Can we get one for the elimination method too?
Also, can you solve the same problem using either of the two techniques?
B. C(n)=0.75n-0.25
C. C(n)=1.0n
D. C(n)=0.75n
Answer:
B. C(n)=0.75n-0.25
Step-by-step explanation:
Given : Cost of one candy = $0.75
There is a coupon of $0.25 off on total purchase .
To Find : Write a function rule for the cost of n pieces of candy.
Solution :
Since we are given that total candies bought = n
Cost of one candy = $0.75
Cost of n candy = $0.75n
So, cost of total purchase = $0.75n
Since on total purchase there is a off of $0.25
So, cost of total purchase after off will be $0.75n -$0.25
⇒C(n)= 0.75n-0.25
Where C(n) denotes the total cost after getting off
Hence Option B is correct.
A function rule for the cost of n pieces of candy is C(n)= 0.75n-0.25
