What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The number of quarters = 1
So , the value of quarters = $ 0.25
The number of cents = 2
So , the value of cents = $ 0.20
The number of nickels = 2
So , the value of nickels = $ 10
And , the equation will be
A = value of quarters + value of cents + value of nickels
On simplifying , we get
A = 0.25 + 0.20 + 0.10
A = $ 0.55
Therefore , the value of the coins is A = $ 0.55
Hence , the equation is A = $ 0.55

Are 2(x - 3) + 1 and 2x + 6 equivalent expressions
Answers
Answer:
No.
Step-by-step explanation:
2(x-3) + 1 = 2x - 6 + 1 = 2x - 5
2x + 6 ≠ 2x -5, so no, they aren't equivalent.
The expression 2(x - 3) + 1 and 2x + 6 are not Equivalent.
What is Equivalent Expression?Equivalent expressions are expressions that perform the same function notwithstanding their appearance. If two algebraic expressions are equivalent, they have the same value when the same value(s) for the variable are used (s).
We have two expressions to compare 2(x- 3) + 1 and 2x +6 .
Now, simplifying the first expression as
= 2(x -3) + 1
= 2x - 6 +1
= 2x - 5
and, the second expression is 2x + 6.
Thus, both of expression are not Equivalent.

Answers
Answer:
mean
Step-by-step explanation:
The method to summarize the data will be mean
The mean of the laps of swim team is 84.1 laps
What is Mean?
The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the data be represented by the set A
Let the mean of the data set be M
The value of set A = { 77 , 79 , 80 , 82 , 84 , 85 , 86 , 87 , 90 , 91 }
The total number of data elements in the set = 10
Now , since all the data elements are distributed normally and does have a central point
So , it follows normal distribution
Therefore , the mean of the data will be
Mean M = Sum of Values / Number of Values
Mean = ( 77 + 79 + 80 + 82 + 84 + 85 + 86 + 87 + 90 + 91 ) / 10
Mean = 841 / 10
Mean M = 84.1 laps
Therefore , the value of M is 84.1
Hence , The method to summarize the data will be mean
The mean of the laps of swim team is 84.1 laps

aₙ = 224(1/2)ⁿStep-by-step explanation:
Given GP with:
a₅ = 7a₆ = 3.5We can find the common ratio:
r = 3.5/7 = 1/2Using the nth term formula we can work out the first term:
aₙ = a₁rⁿ⁻¹a₅ = a₁(1/2)⁴7 = a₁ (1/16)a₁ = 7*16a₁ = 112So the explicit rule is:
aₙ = 112(1/2)ⁿ⁻¹ = 224(1/2)ⁿ
