If 4(n−3)+2n=12, what is the value of n?
Answer:
n=4
Step-by-step explanation:
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]4(n - 3) + 2n = 12[/tex]
[tex]4n - 12 + 2n = 12[/tex]
[tex]6n - 12 = 12[/tex]
Add sides 12
[tex]6n - 12 + 12 = 12 + 12[/tex]
[tex]6n = 24[/tex]
Divide sides by 6

17=−13−8x
Answer:
x=-15/4 or -3.75
Step-by-step explanation:
17=−13−8x
30=-8x
x=30/-8 --> -15/4 or -3.75
Answer:
0.5
Step-by-step explanation:
It's simple really,
What you do is first add -13 from 17 and you get 4
17+-13=4
then you divide by 8 and you get 0.5.
4(divided by)8=0.5
Hope that helps you!

Evaluate the double integral. 4y2 dA, D is the triangular region with vertices (0, 1), (1, 2), (4, 1)
Answer:
44/3
Step-by-step explanation:
Let A be the line joining the vertices (0, 1) and (1,2) while B be the equation of the line joining (1, 2) and (4, 1).
The equation of a line joining points [tex](x_1,y_1) \ and\ (x_2,y_2)\ is:\\\\[/tex]
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
The equation of line A joining (0, 1) and (1,2) is:
[tex]y-1=\frac{2-1}{1-0} (x-0)\\\\y-1=x\\\\x=y-1[/tex]
The equation of line D joining (1, 2) and (4,1) is:
[tex]y-2=\frac{1-2}{4-1} (x-1)\\\\y-2=-\frac{1}{3} (x-1)\\\\3y-6=-x+1\\\\x=-3y+7[/tex]
Therefore the change in y is: 1 ≤ y ≤ 2, while change in x is: y-1 ≤ x ≤ -3y + 7. Hence the double integral is:
[tex]\int\limits^2_1\int\limits^{-3y+7}_{y-1} {4y^2} \, dx dy\\\\=4\int\limits^2_1\int\limits^{-3y+7}_{y-1} {y^2} \, dx dy\\\\=4\int\limits^2_1y^2dy[x]^{-3y+7}_{y-1} \\\\=4\int\limits^2_1y^2dy(-3y+7-(y-1))\\\\=4\int\limits^2_1y^2dy(-4y+8)\\\\=4\int\limits^2_1(-4y^3+8y^2)dy\\\\=4[-y^4+\frac{8}{3}y^3 ]^2_1\\\\=4(\frac{11}{3} )\\\\=\frac{44}{3 }[/tex]
To answer this question, we need, first get the equations for the lines that enclosed the surface, and integrate according to the limits obtained from these equations give.
The solution is:
A = 44/3 square units
Let´s call points:
P ( 0 , 1 ) Q ( 1 , 2 ) and R ( 4 , 1 )
The equation for the line between, P and R is:
y = 1
The equation for the line between, P and Q is:
Slope-intercept equation is y = m×x + b
The slope m₁ = ( 2 - 1 ) / ( 1 - 0 ) m₁ = 1
and the line passes over the point x = 0 y = 1 ; then
1 = 0 +b b = 1
y = x + 1 ⇒ x = y - 1
The equation for the line between Q and R is:
m₂ = ( 1 - 2 ) / ( 4 - 1) m₂ = - 1/3
y = ( -1/3)× x + b
when x = 1 y = 2
2 = ( - 1/3)×(1) + b
2 + 1/3 = b
b = 7/3
y = - (x/3) + 7/3 ⇒ x = 7 - 3×y
The double integral becomes:
A = 4×∫∫ y² dx dy ⇒ A = 4 ×∫₁² y²dy ∫dx | (y - 1 ) y ( 7 - 3y)
A = 4×∫₁² y²dy × x | ( y - 1 ) y ( 7 - 3y)
A = 4 ×∫₁² y²dy × [ 7 - 3×y - ( y - 1 )]
A = 4 ×∫₁² y²dy × (8 - 4×y ) ⇒ A = 4 ×∫₁² (8×y² - 4×y³ ) dy
A = 4 × [ (8/3)×y³ - y⁴ | ₁²
A = 4 × [ 64/3 - 16 - (8/3) + 1 ]
A = 4 × ( 56/3 - 15 )
A = 4 × ( 56 - 45 /3)
A = 4 × 11/3
A = 44/3 square units

f(x) = 2x3 + 3x2 – 7x + 2
g(x) = 2x – 5
Find (f + g)(x).
Answer:
(f + g)(x) = 2x³ + 3x² - 5x - 3 ⇒ B
Step-by-step explanation:
Let us solve the question
∵ f(x) = 2x³ + 3x² -7x + 2
∵ g(x) = 2x - 5
→ (f + g)(x) means add f(x) and g(x)
∴ (f + g)(x) = (2x³ + 3x² - 7x + 2) + (2x - 5)
→ Add the like terms
∵ (f + g)(x) = 2x³ + 3x² + (-7x + 2x) + (2 - 5)
∴ (f + g)(x) = 2x³ + 3x³ + (-5x) + (-3)
→ Remember that (+)(-) = (-)
∵ 2x³ + 3x³ + (-5x) + (-3) = 2x³ + 3x² - 5x - 3
∴ (f + g)(x) = 2x³ + 3x² - 5x - 3

A flower vase has a volume of 1480 cubic centimeters (cm3). Use the fact
that 1 inch is equal to 2.54 cm to convert this volume to cubic inches (in).
Round your answer to the nearest tenth. Do not type the units in the space
below.
Answer:
The volume of the flower vase is 90.3 cubic inches.
Step-by-step explanation:
Dimensionally speaking, volume [tex][V][/tex] is equivalent to the product of length [tex][L][/tex], length [tex][L][/tex] and length [tex][L][/tex]. That is:
[tex][V] =[L]\times [L]\times [L][/tex]
In this case, an inch equals 2.54 centimeters and we proceed to convert the given volume of the flower vase as follows:
[tex]V = 1480\,cm^{3}\times \frac{1\,in\times 1\,in\times 1\,in}{2.54\,cm\times 2.54\,cm\times 2.54\,cm}[/tex]
[tex]V = 90.3\,in^{3}[/tex]
The volume of the flower vase is 90.3 cubic inches.
What percent of 16 is 50% of 50% of 48?
Answer:
150
Step-by-step explanation:
x %* 16 = 50% * 48
[tex]\frac{x}{100} = \frac{0.5 *48}{16} = \frac{24}{16} = \frac{6}{4} = \frac{3}{2} \\x = \frac{300}{2} = 150\\[/tex]
I guessed 50% is typed wrongly twice so I solved once with 50%
75% of 16 is equal to 50% of 50% of 48.
Percentage of 16 equivalent to 50% of 50% of 48 to be evaluate.
Percentage is the matter of composition per unit whole composition.
Let x% of 16 = 50% of 50% of 48
x/100 *16 = 1/2*1/2*48
x/100*16 = 12
x = 12/16 * 100
x = 75%
Thus, 75% of 16 is equal to 50% of 50% of 48.

Mrs. Peterson makes ceramic figurines. She recently made 25 figurines. Of those figurines, 16 are animals. What percent of the figurines are NOT animals?
Answer:
Depends on how many digits the question wants. If rounded, 38%. Or just 37%
Step-by-step explanation:
She made 25 in all.
16 of them are animal figures. The question is asking what percent is NOT animal figure, so we need to subtract 25 by 16. That gives us 9. To find the percent, we need to divide 9 by the whole, which is 24. 9/24=0.375
The answer is 37% or 37.5% (It depends on how many digits the question is asking for. Also try rounding (38%).
