Answer:
5n = $10.25
Step-by-step explanation:
We know that the tub is 5 pounds, and costs $10.25. We also know that n is in dollars per pound. Dollars per pound can be written as the product of dollars, divided by pounds, so we can plug that in being n = $10.25/5, next we want to make the equation contain an integer on both sides and not contain any fractions, so we multiply both sides by 5, resulting in 5n = $10.25

solve this question
a=7+3
Answer:
10Step-by-step explanation:
The answer is 10 because 7 + 3 equals 10!
This can be proven by adding 7 + 3 or by subtracting in a certain way.
7 + 3 = ?
7 + 1 = 8
7 + 2 = 9
7 + 3 = 10
You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.
If you subtract 7 by 10, ( 10 - 7 ) then you get 3
If you subtract 3 by 10, ( 10 - 3 ) then you get 7
If the number you subtracted matches the number that you didn't subtract, then your answer is correct.

How much should be added to the sum of 25 1/6 and 7 2/5 to get 60?
Answer:
3.77 should be added
hope it helps.
Answer:
823/30
or 27 13/30
decimal: 27.43
Step-by-step explanation:
(25+7)+ (1/6 + 2/5)
32+ (5/30 + 12/30)
32+ 17/30
= 32 17/30
60- 32 17/30
= 1800/30 - 977/30
= 823/30
= 27 13/30
Jordan is buying plastic plates for a party.The plates usually cost $2.40 per 10 plates,but they are on sale for 30% off usual price.If jordan buys 50 plates,how much will they cost
30% off means they are paying 70% of the original price.
Sale price = 2.40 x 0.70 = $1.68 for 10 plates
50 plates / 10 = 5
They buy 5 packages of plates.
1.68 x 5 = $8.40
Total price = $8.40
Answer:
Step-by-step explanation:
2.40 X 5 =$12
12 X 0.3=$3.6 off
12-3.6=$8.40
Therefore it'll cost $8.40
Which graph represents the solution to the compound inequality?
-6<3x-12 s9
1 2
O
o3 6 9 12 15
O 30 369 12 15
Step-by-step explanation:
-6 < 3x - 12 <= 9
6 < 3x <= 21 (add 12)
2 < x <= 7 (divide by 3)
The graph that correct represents this solution set is the 2nd graph.
Given the function f(x) = 2-4, determine the slope of the tangent line of f at
x = -1 using the limit shown below. You do not have to simplify your answer.
Answer:
Slope of the tangent line at x=-1
[tex](\frac{dy}{dx})_{x=-1} = e^{-5}[/tex]
Step-by-step explanation:
Explanation:-
Given function
y = f(x) = e ˣ⁻⁴ ...(i)
Differentiating equation (i) with respective to 'x' , we get
[tex]\frac{dy}{dx} = e^{x-4} \frac{d}{dx} (x-4)[/tex]
[tex]\frac{dy}{dx} = e^{x-4} (1)[/tex]
Slope of the tangent line
[tex](\frac{dy}{dx})_{x=-1} = e^{-1-4} = e^{-5}[/tex]
Can someone please help me with this question!!! Pick The correct layout
Answer:
B
Step-by-step explanation:
x + y = 90
Your x and y will give you a sum of 90
y= 4x + 6
Your y will be 6+ more then 4 TIMES x
therefore you would do 4 times x plus 6 equals y
Can some one help me?
Answer:
W = 10 cm
Step-by-step explanation:
Area of a Triangle and a Rectangle
The area of a triangle of base B and height H is:
[tex]\displaystyle A_t=\frac{BH}{2}[/tex]
The area of a rectangle of width W and length L is:
[tex]A_r=WL[/tex]
We are given the base of the triangle B=6 cm and the height H=8 cm, thus the area is:
[tex]\displaystyle A_t=\frac{6*8}{2}= 24\ cm^2[/tex]
The area of the rectangle is 5 times the area of the triangle, thus:
[tex]A_r=5*24\ cm^2=120\ cm^2[/tex]
If we know the area of the rectangle and its length, we can find the width by solving for W:
[tex]\displaystyle W=\frac{A_r}{L}[/tex]
The rectangle has a length of L=12 cm, thus:
[tex]\displaystyle W=\frac{120}{12}=10\ cm[/tex]
W = 10 cm

Explain it too and what specific polynomial subject.
Answer:
C
Step-by-step explanation:
Expand the factors and compare the coefficients of like terms.
Given
(mx + 2)(3x - 5) ← expand using FOIL
= 3mx² - 5mx + 6x - 10
Compare to 12x² - 14x - 10
For the 2 to be equal, then the coefficients of like terms must be equal.
Compare coefficients of x² terms
3m = 12 ( divide both sides by 3 )
m = 4 → C

Riley buys ice cream and oranges at the store.
She pays a total of $37.15.
She pays a total of $3.62 for the ice cream.
She buys 7 bags of oranges that each cost the same amount.
How much does each bag of oranges cost?
Answer:
4.79 dollars.
Step-by-step explanation:
7x + 3.62 = 37.15
7x= 37.15-3.62
7x=33.53
x= 33.53/7=4.79 dollars.
Identify the like terms:
4x - 7+ 6y + 2x + x + 16 - 3x
Answer:
4x−7+6y+2x+x+16−3x

The graph of g is the graph of translated horizontally 5 units to the right. If f(x) = 3x + 2 , what is the equation of the function g?
Answer:
f(x) = 3(x-5) + 2
Step-by-step explanation:
The x coordinates are all shifted to the right, which is the positive direction. Subtracting 5 from the x coordinate is a horizontal right shift.
If f(x)=4x-2 and g(x)=-8x+7, find h(x)=f(x) - g(x)
Please help and explain.
Thank you. :)
Answer:
[tex]h(x)=12x-9[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=4x-2\text{ and } g(x)=-8x+7[/tex]
And we want to find:
[tex]h(x)=f(x)-g(x)[/tex]
So, by substitution:
[tex]h(x)=(4x-2)-(-8x+7)[/tex]
Simplify. Distribute:
[tex]h(x)=(4x-2)+(8x-7)[/tex]
Rearrange:
[tex]h(x)=(4x+8x)+(-2-7)[/tex]
Combine like terms. Hence:
[tex]h(x)=12x-9[/tex]

R holdA company claims that their new bottle holds 25% more laundry soap. If their original container held 53 fluid ounces of soap, how much does the new containe?
Answer:
66.25 fluid ounce
Step-by-step explanation:
Given that :
Capacity of original container = 53 fluid ounces
Percentage addition of new container = 25%
Capacity of new container :
Capacity of original container * ( 1 + percentage addition)
53 * ( 1 + 0.25)
53 * (1.25)
= 66.25 fluid ounce

Answer: (2) (-8,10]
Step-by-step explanation:
Answer:
(2) (-8, 10]
Step-by-step explanation:
First, note that a bracket (“[“ and “]”) is inclusive and a parentheses ( “(“ and ”)” ) are exclusive.
For -8< x <= 10, -8 is excluded in the interval because x must be GREATER THAN (since -8 isn’t greater than -8) and 10 is inclusive in the interval because x must LESS THAN OR EQUAL TO 10 (since 10 is greater than or equal to 10).
So, using what we know, we put it together into interval notation: (-8, 10]
