Answer:
y=3 you have to use PEMDAS
Answer:
y=3
Step-by-step explanation:
Combine multiplied terms into a single fraction
2.4y-3.2=4
12y/5 -3.2=4
Add 3.2 to both sides of the equation
12y/5- 3.2+3.2=4+3.2
Simplify
add the numbers 12y/5=7.2
Solution
y=3

What is the first step to solving the equation 12 - y = 18?
Answer:
subtract 12 from 18
Step-by-step explanation:
Answer:
No real "first step" as there are many ways to do it. If I were to do it, I would add the y to the other side to make it positive. This thus eliminates any negative variables in the equation

A car is purchased for £11 500 In its first year, the value of the car will depreciate by 15%. Each year after that, the value of the car will depreciate by 10%. What is the value of the car at the end of 3 years?
Answer:
Value of the car at the end of 3 years is £7917.75
Step-by-step explanation:
The car is purchased for £11500.
In the first year, 15% depriciation.
So, depreciation on first year =11500 *[tex]\frac{15}{100}[/tex] =1725
After first year depreciation the value of car =11500-1725 =£9775
Now, second year depreciation is 10%
So, 10% of 9775 =0.10*9775 =977.5
Value of car after 2 years = 9775 -977.5 =8797.5
Now, for third year depreciation is 10%.
So, depreciation on 3 year = 10% *8797.5
=0.10*8797.5
=879.75
So, value of car after 3 years = 8797.5 -879.75 =£7917.75
what can you double and then add -6 to get -16
Answer:
- 5
Step-by-step explanation:
let the number be n then double is 2n , so
2n + (- 6) = - 16
2n - 6 = - 16 ( add 6 to both sides )
2n = - 10 ( divide both sides by 2 )
n = - 5
The number is - 5

What is the volume???
Answer:
First find out the other side measurements. Then split the shape into seperate squares and find the area then add them all up.
Step-by-step explanation:
volume is length × width × height.
Answer:
240 cm cubed
Step-by-step explanation:
If you separate the shape into 2 figures, the first figures area is 180
and the second is 60.
180 + 60 = 240

What percent of 120 is 72?
Show the equation and all work. HELP ASAP
We already have our first value 120 and the second value 72. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
Y = [tex]\frac{72}{120}[/tex]
By multiplying both numerator and denominator by 100 we will get:
Y = [tex]\frac{72}{120}[/tex] × [tex]\frac{100}{100}[/tex] = [tex]\frac{60}{100}[/tex]
Therefore, we get y = 60
You can also find percent of 120 is 72, just by entering 72 ÷ 120 × 100 and you will get your answer which is 60.

Nakato Nobuki, a Japanese artist, intends to withdraw $ 24,000.00 from his savings at the end of 5 years. Mr. Nobuki deposits $ 1,500.00 in savings annually and today has a balance of $ 8,000.00. What should be the savings interest rate for Nobuki to achieve his goals?
Answer:
The savings interest rate of Nakato Nobuki is 3 %
Step-by-step explanation:
Given;
Final amount of Nakato Nobuki, A = $ 24,000.00
time period of his investment, t = 5 years
principla amount, P = $ 1,500.00
The savings interest rate of Nakato Nobuki can be calculated on a simple interest basis.
A = P(1 + rt)
r is the savings interest rate
Substitute the given values and solve for r
24,000 = 1,500(1 + 5r)
24,000 = 1,500 + 7,500r
7,500r = 24,000 - 1,500
7,500r = 22,500
r = 22,500/7,500
r = 3 %
Therefore, the savings interest rate of Nakato Nobuki is 3 %

The range of the given function from the given graph are: all values of y that are greater than or equal to -3. Therefore, the correct option is option D.
What is range of function?It is seen to be best practice to define the word "range" the first time it appears in a book or article because it might have several different meanings. When the word "range" is used in older literature, it frequently refers to what is today known as the codomain.
If more recent texts use the phrase "range" at all, they typically do so to refer to what is now known as the image. Several contemporary novels shouldn't use the term "range" at all to avoid any misunderstandings.
A function's range is the set of each of its potential outputs1,2,3,4. That's the output that the function generates when all of its inputs are used3,5. The range of the given function from the given graph are: all values of y that are greater than or equal to -3.
Therefore, the correct option is option D.

Answer:
53°
Step-by-step explanation:
ΔABC is a right triangle (one of the angles is 90°).
You can use SOH-CAH-TOA to find an angle:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
In this case, we want to find ∠A. We know the lengths of the opposite side and the hypotenuse. Therefore, we should use sine.
sin A = 12 / 15
m∠A = sin⁻¹(12/15)
m∠A ≈ 53°
Alternatively, you could use Pythagorean theorem to find the third side, then use either cosine or tangent to find m∠A.

53

Encontrar las coordenadas del centro y la longitud del radio de la circunferencia 9x²+9y²+18x-12+10=0
Answer:
Step-by-step explanation:
The standard form of equation of a circle is expressed as;
x^2+y^2+2gx+2fy+c = 0
The centre is at (-g, -f)
Given the equation'
9x²+9y²+18x-12+10=0
Divide through by 9
9x²/9+9y²/9+18x/9-12y/9+10/9=0
x^2+y^2+2x-4/3 y + 10/9 = 0
Compare
2gx = 2x
g = 1
2fy = -4/3 y
2f = -4/3
f = -4/6
f = -2/3
The centre is (-(-2/3), -1) = (2/3, -1)
for the radius
r = √f²+g²-c
r =√(-2/3)²+1²-10
r =√4/9 - 9
r = √(4-81)/9
r = √-77/9

Does the table below represents a linear function why or why not
Answer:
No, it's not linear function.
Step-by-step explanation:
The x value repeatedly adds 3.
So far its a linear function.
If you look at the y value, it does NOT have a pattern, therefore that means it is NOT a linear function.
why is y = 3.5 x proportional
Answer:
Step-by-step explanation:
A proportion is being directly related to something, meaning that there is just multiplication or division (just a coefficient in front of the x-coordinate, nothing more).
In a graph, a proportional graph is a graph that goes straight through the origin.

A basketball shaped like a sphere has a diameter of 8 inches. Which measurement is
to the volume of the basketball in cubic inches?
Answer:
268
Step-by-step explanation:
The volume formula for a sphere is: V= [tex]\frac{4}{3}\pi r^{3}[/tex]
We also know that [tex]\pi[/tex] is approximately 3.14.
You have to know these in order to solve the question..
Since we also know the diameter is 8 we can also find the radius (r) ,which is half of the diamater so 4.
Now all we need to do it plug in the numbers.
V= [tex]\frac{4}{3}[/tex](3.14)[tex]4^{3}[/tex]
Now solve for the equation.
V=267.94...
So rounded that is 268.

The chess club has a budget of at least $300 that the members can spend for the field trip. There are 20 people in the chess club. They get a discount of $60 for transportation for the field trip. What is the minimum that each member
of the chess club can spend on the trip?
Answer:
$12
Step-by-step explanation:
We are told that there are 20 people in the chess club and each got a discount of $60 for transportation on the field trip.
Let the amount spent by each member is x
Since there are 20 of them and the budget is at least $300 and they get a discount of $60, it means that;
20x ≥ 300 - 60
20x ≥ 240
Divide both sides by 20 to get;
x ≥ 12
Thus, minimum amount each member can spend is $12.
