solve 12x + k = c for x and what are the steps?
Answer:
[tex] \huge \orange { \boxed{x = \frac{c - k}{12} }}[/tex]
Step-by-step explanation:
12x + k = c
Step 1: transfer k on right side
12x = c - k
Step 2: Divide both side by 12
[tex] \frac{12x}{12} = \frac{c - k}{12} \\ \huge \red{ \boxed{x = \frac{c - k}{12} }}[/tex]

14) ¿Cuántos cubos de 1 cm por lado caben dentro de otro cubo que mide por lado 2cm?
Answer: 8
Step-by-step explanation:
Ok, el volumen de un cubo de lado L es:
V = L^3
Entonces, el volumen de un cubo de 1cm por lado es:
V = (1cm)^3 = 1cm^3
Y el volumen de cubo cuyos lados miden 2cm es:
V' = (2cm)^3 = 8cm^3.
Ahora, la cantidad de cubos chicos que van a entrar en el cubo grande es igual al cociente entre sus volúmenes:
V'/V = (8cm^3)/(1cm^3) = 8
Entran 8 cubos de 1 cm por lado en un cubo de 2cm por lado.
using appropriate properties, find the value of 249² - 248²
Answer:
[tex]\boxed{\bold{\huge{\boxed{497}}}}[/tex]
Step-by-step explanation:
=> [tex]\sf 249^2 - 248^2[/tex]
Using Formula [tex]\sf a^2 - b^2 = (a+b)(a-b)[/tex]
Where
a = 249
b = 248
=> [tex]\sf (249+248)(249-248)[/tex]
=> [tex]\sf (497)(1)[/tex]
=> 497

Its pitcher is shaped like a cylinder with a radius of 1 centimeter and a height of 7.8 cm. What's this pitcher plant's approximate volume?
Answer:
The pitcher plant's approximate volume is 24.492 [tex]\text{cm}^{3}[/tex].
Step-by-step explanation:
We are given that a pitcher is shaped like a cylinder with a radius of 1 centimeter and a height of 7.8 cm.
Let the radius of a cylinder = r = 1 cm
and the height of a cylinder = h = 7.8 cm
As we know that the volume of a cylinder is given by;
The volume of a cylinder = [tex]\pi r^{2}h[/tex]
= [tex]3.14 \times 1^{2} \times 7.8[/tex] {taking approximate value of [tex]\pi[/tex] to be 3.14}
= [tex]3.14 \times 7.8[/tex]
= 24.492 [tex]\text{cm}^{3}[/tex]
Hence, this pitcher plant's approximate volume is 24.492 [tex]\text{cm}^{3}[/tex].

Write an equation of a line in point-slope and slope intercept form that passes through the point (1, -8) and is perpendicular to the line: 2x-4y = -11
Answer:
11y-2x= -90
Step-by-step explanation:
for the point (1,-8)
x=1 and y= -8
for the equation,
2x -4y= -11
x= -1/m
m= -1/x
x = -1/ (-11/2 )
m= 2/11
so for the equation,
y-y1= m(x- x1)
y- -8=2/11(x-1)
11(y+8)= 2(x-1)
11y +88= 2x-2
11y-2x= -90
Does anyone know how to do this one
Which of the following ordered pairs is not a solution of the system of inequalities? y > x2 – 4x – 5 y < –x2 – 5x + 6 Question 62 options: A) (1, 7) B) (1, –7) C) (1, –5) D) (–1, 6)
Answer:
a) (x, y) = (1, 7)
Step-by-step explanation:
Let be the following system of inequalties:
[tex]y > x^{2}-4\cdot x -5[/tex]
[tex]y < -x^{2}-5\cdot x +6[/tex]
We can find the right option by evaluating each option in the system of inequalities:
a) (x, y) = (1, 7)
[tex]7 > 1^{2}-4\cdot (1) -5[/tex]
[tex]7 < -1^{2}-5\cdot (1) +6[/tex]
Then,
[tex]7>-8[/tex] (TRUE)
[tex]7<0[/tex] (FALSE)
(1, 7) is not a solution of the system of inequalities.
b) (x, y) = (1, -7)
[tex]-7 > 1^{2}-4\cdot (1) -5[/tex]
[tex]-7 < -1^{2}-5\cdot (1) +6[/tex]
Then,
[tex]-7 > - 8[/tex] (TRUE)
[tex]-7< 0[/tex] (TRUE)
(1, -7) is a solution of the system of inequalities.
c) (x, y) = (1, -5)
[tex]-5 > 1^{2}-4\cdot (1) -5[/tex]
[tex]-5 < -1^{2}-5\cdot (1) +6[/tex]
Then,
[tex]-5 > - 8[/tex] (TRUE)
[tex]-5< 0[/tex] (TRUE)
(1, -5) is a solution of the system of inequalities.
d) (x, y) = (-1, 6)
[tex]6 > (-1)^{2}-4\cdot (-1) -5[/tex]
[tex]6 <(-1)^{2}-5\cdot (-1)+6[/tex]
Then,
[tex]6>0[/tex] (TRUE)
[tex]6 < 12[/tex] (TRUE)
(-1, 6) is a solution of the system of inequalties.
Therefore, we conclude that correct answer is A.

Step-by-step explanation:
Is the following relation a function ? S = {(1,2),(2,2),(-2,2)} justify your answer
Answer:
YESStep-by-step explanation:
relation is a function if we have y for every x from domain and for one x we have one and only one y
x = 1 --> y = 2
x = 2 --> y = 2
x = -2 --> y = 2
no x-es without y-es
and no two the same x-es with one y
so this relation is a function

Esme buys jacketsfor 500 each and prices them for 700 each.If the selling price is reduced by 20%. how much profitdoes Esme make on each items .
Answer:
($) 60 is the profit per item when the selling price is reduced by 20%
Step-by-step explanation: 20% of 700 is 140.
The original profit is 700 - 500 = 200. The selling price is 140 less, Subtract 140 from 200. That leaves a profit of 60. (Not necessarily dollars, as the currency was not given in the question.)

I think it may be 31%
Answer:
50%
Step-by-step explanation:
There are a total of 640 fries.
40% of them are crispy. Therefore, let C be the amount of crispy fries:
[tex]C=0.4(640)=256[/tex]
Thus, the amount of soggy fries S would be:
[tex]S=640-256=384[/tex]
The total of the crispy fries and the soggy fries is the sum of the fries not on the floor and on the floor. Let F denote on the floor and let NF denote not on the floor. Thus:
[tex]C=C_F+C_{NF}[/tex]
C is 256:
[tex]256=C_F+C_{NF}[/tex]
Same thing for soggy fries S:
[tex]S=S_F+S_{NF}\\[/tex]
S is 384, thus:
[tex]384=S_F+S_{NF}[/tex]
We are told that 80% of the soggy fries are on the floor. Therefore:
[tex]S_F=0.8(384)=307.2[/tex]
This means that the amount of soggy fries not on the floor is:
[tex]S_{NF}=S-S_F\\S_{NF}=384-307.2=76.8[/tex]
We are given that 32% of all the fries are not on the floor. Therefore:
[tex]NF=0.32(640)=204.8[/tex]
The total amount of fries not on the floor is the sum of the amount of crispy fries and soggy fries not on the floor. Thus:
[tex]NF=C_{NF}+S_{NF}[/tex]
We know that NF is 204.8 and that S(NF) is 76.8. Substitute:
[tex]204.8=C_{NF}+76.8[/tex]
Subtract 76.8 from both sides:
[tex]C_{NF}=128[/tex]
This means that out of the 256 crispy fries, only 128 of them are not on the floor.
This means that the amount on the floor is 256-128, or also 128.
Thus, the percentage of crispy fries on the floor is:
[tex]=\frac{128}{256}=50%[/tex]

Caleb is at the grocery store and plans on buying cans of soup and frozen dinners, but
is concerned about their sodium content. Each can of soup has 500 mg of sodium and
each frozen dinner has 650 mg of sodium. How many milligrams of sodium are there
in 3 cans of soup and 4 frozen dinners? How many milligrams of sodium are there in
c cans of soup and f frozen dinners?
Answer:
Look at the step by step
Step-by-step explanation:
3 cans of soup: 1500 mg of sodium
4 frozen dinners: 2600 mg of sodium
together they are 4100 mg of sodium
How many milligrams of sodium are there in c cans of soup: [tex]500c[/tex]
How many milligrams of sodium are there in f frozen dinners: [tex]650f[/tex]
There is 4100 mg of sodium together in 3 cans and 4 frozen dinner. 500c milligrams of sodium is there in c cans of soup and 650f milligrams of sodium is there in f frozen dinners
What is Expression?An expression is combination of variables, numbers and operators.
Each can of soup has 500 mg of sodium and
each frozen dinner has 650 mg of sodium
1 can =500mg
frozen dinner = 650 mg
3 cans=3(500)=1500 mg
4 frozen dinner = 4(650) mg=2600 mg
Together there is 1500+2600= 4100 mg of sodium
500c milligrams of sodium is there in c cans of soup
650f milligrams of sodium is there in f frozen dinners
Hence, there is 4100 mg of sodium together in 3 cans and 4 frozen dinner. 500c milligrams of sodium is there in c cans of soup and 650f milligrams of sodium is there in f frozen dinners
