Answer:
y = 31
Step-by-step explanation:
2y-5+123=180
123 - 5 = 118
2y+118=180
subtract 118 from both sides
2y+118 - 118 = 180 - 118
180 - 118 = 62
2y = 62
divide 2 by both sides
2y/2 = 62/2
y = 31
Answer:
Step-by-step explanation:
2y+−5+123=180
Step 1: (Combine Like Terms)
(2y)+(−5+123)=180
Step 2: (Subtract 118 from both sides)
2y+118−118=180−118
2y=62
Step 3: Divide both sides by 2
2y/2= 62/2
y=31
In your own words, tell me the difference between a geometric and an arithmetic sequence.
As several differences are there between them and is differentiated below.
What is Sequence?
A list of numbers in a specific order is called a sequence. The terms of the sequence are the various numbers that appear in it.
Let a sequence's terms be a1, a2, a3,..., an,..., etc.
The term's position is indicated by the subscripts. That implies,
Initial phrase = a1
term two = a2
term three Equals a3
….
The nth term, indicated by an, is the number that appears in the sequence at the nth place. This phrase is also known as the sequence's general phrase.
Geometric Sequence:
It is a sequence of numbers in which each new term is calculated by multiplying by a non-zero and fixed number.Multiplication or Division is done in every step.A common ratio between 2 successive terms is the common ratio.It is of the Exponential Form.Arithmetic Sequence:

during basketball season josh made 3 out of every 7 free throw attempts in the last game josh attempted 28 free throws how many free throws would he have been expected to make
There are 12 free throws would he have been expected to make.
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.
Given that;
During basketball season josh made 3 out of every 7 free throw attempts in the last game.
Now,
Since, During basketball season josh made 3 out of every 7 free throw attempts in the last game.
Hence, Let number of free throws would he have been expected to make for attempted 28 free throws = x
So, We can formulate;
⇒ 3/7 = x/28
Solve for x as;
⇒ 3 × 28 / 7 = x
⇒ x = 3 × 4
⇒ x = 12
Thus, There are 12 free throws would he have been expected to make.

Jordan is helping his dad build a doghouse. The floor is rectangle-shaped with a width of 5 feet and an area of 36.25 ft2. What is the length of the rectangular floor?
The length is 7.25 feet
Here the detail
The formula for rectangled-shaped area is multiply length and width
Area = Length x Width
In this case, we know that the area is 36.25 ft2 and the width is 5 feet
so we can divided the area and the width to solve the length
Area = Length x Width
36.25 = Length x 5
Length = 36.25 : 5
Length = 7.25 feet
Hence the length of the rectangular floor is 7.25 feet

Find the present value (the amount that should be invested now to accumulate the following amount) if the money is compounded as indicated.
$6800 at 4% compounded quarterly for 3 years
The present value the amount that should be invested now to accumulate is $7662.24.
What is meant by compound interest?Compound interest is the adding of interest to the principal amount of a loan or deposit, or interest on interest + principal. It is the outcome of reinvesting interest, or adding it to lent capital, rather than paying it out or requesting payment from the borrower, so that interest is received on the principle sum plus previously accumulated interest in the next month. In finance and economics, compound interest is common.
Compound interest differs from simple interest in that previously collected interest is not added to the current period's main amount, resulting in no compounding. The simple annual interest rate is calculated by multiplying the interest amount per period by the number of periods in a year.
Given,
Principle P=$6800
T=3 years
And also given that the money is compounded quarterly.
Present value=P[tex](1+(R/4)^{4t}[/tex]
=6800[tex](1+(4/400)^{12}[/tex])
=6800[tex](1+(1/100))^{12}[/tex]
=6800[tex](101/100)^{12}[/tex]
=6800[tex](1.01)^{12}[/tex]
=6800×1.1268

Susan has a collection of 60 nickels and dimes. If the number of nickels is four times the number of dimes, how many nickels and how many dimes does she have?
Answer: 12 dimes, 48 nickles.
Step-by-step explanation:
Let x = the number of dimes
Let 4x = the number of nickels
x + 4x = 60
5x = 60
x = 12 dimes
4x = 48 nickles
She has 48 nickels and 12 dimes.
Equation
At first, we have to express the sentence into equation:
Given:
x = nickels
y = dimes
Susan has a collection of 60 nickels and dimes --> x + y = 60 ............. (1)
the number of nickels is four times the number of dimes --> x = 4y ......(2)
then we must input the equation (2) into the equation (1):
x + y = 60
4y + y = 60
5y = 60
y = 60/5
y = 12
As we know the value of y, we can calculate the value of x from the equation (2):
x = 4y
x = 4 * 12
x = 48
Thus, Susan has 48 nickels and 12 dimes

One rectangle is "framed" within another. Find the area of the shaded region if the "frame" is 2 units wide. 7 and 2
24 units is the area of the shaded region if the "frame" is 2 units wide.
What is Area of Rectangle?The area of Rectangle is length times of width
We know that the frame is 2 units wide, and the measure of the rectangle and the frame are:
width = 7 units
length = 12 units
Now, if we remove the frame, we will remove 2×2 units = 4 units for each measure (because for each measure we have the frame in both sides).
So the measures for the shaded rectangle are:
width = 7 units - 4 units = 3 units
length = 12 units - 4 units = 8 units.
And the area of a rectangle is given by the product between the width and length, then we have:
A = (3 units)*(8 units) = 24 square units.
Hence, 24 units is the area of the shaded region if the "frame" is 2 units wide.

Your car has a 15 gallon tank and can run on fuel with added
ethanol. The fuel contains either 13 percent ethanol or 69 percent
ethanol. How much of 69% percent ethanol fuel should you use so
that your tank is 40 percent ethanol?
Answer: 7.5
Step-by-step explanation:
the tank is 15 gallons and you can get 13 percent ethanol or 69 percent ethanol, so you simply just get 7.5gallons of 69 percent and then 7.5 gallons of 13 percent
.69 divided by 15 is .046
.13 divided by 15 is .008
The amount of 69% percent ethanol fuel should you use so that your tank is 40 percent ethanol is equivalent to 4.35 gallons.

ethanol. The fuel contains either 13 percent ethanol or 69 percent
ethanol.
The amount of 69% percent ethanol fuel should you use so that your tank is 40 percent ethanol is given by -
{x} = 69% of 15 - {40% of 15}
{x} = (69/100 x 15) - (40/100 x 15)

A fence is to be built to enclose a rectangular area of 1250 square feet. The fence along three sides is to be made of material that costs $6 per foot. The material for the fourth side costs $18 per foot. Find the dimensions of the rectangle that will allow for the most economical fence to be built
The dimensions of the rectangle for the most economical fence are length, L = 50 feet and width, W = 25 feet
How to find the dimensions of the rectangle for the most economical fence?Given: Area = 1250 square feet, , cost of material along three sides = $6 per foot, cost of material for fourth sides = $18 per foot
In order to calculate the dimension of the fence
Let L and W represent the length and width of the fence respectively
Thus, the area of the fence can be represented as:
A = L × W = 1250 ---- (1)
L = 1250/W
Let the total cost to construct the fence be 'C' can be obtained if we construct the shorter side with material with a cost of $18 per foot
C = 6×(2W + L) + 18×L
C = 12W + 24L ---- (2)
Substituting the value of L from equation 1 into equation 2 we have:
C = 12W + 24×(1250/W)
To minimize the cost we differentiate both sides with respect to W and equate the result to zero:
C = 12W + 24×(1250/W)
dC/dW = d/dW (12W + 30000/W)
0 = 12 - 30000/W²
12W² = 30000
W² = 2500
W = 50 feet
Since L = 1250/W
L = 1250/50
L = 25 feet
Therefore, the dimensions of the rectangle are length of 25 feet and width of 50 feet
