Mariana solved the equation below. Identify her ERROR and EXPLAIN what she did wrong. -3(2x-4)=-12 -6x-12=-12 -6x=0 x=0
Answer:
Her error was multiplying -3 and -4 which gives +12 but she wrote -12 instead
Step-by-step explanation:
Mariana workings:
-3(2x - 4) = -12
-6x - 12 = -12
Her error was multiplying -3 and -4 which gives +12 but she wrote -12 instead
-6x = 0
x=0
Correct workings:
-3(2x - 4) = -12
-6x + 12 = - 12
-6x = -12 - 12
-6x = -24
x = -24/-6
x = 4

Answer:
x = 11
y = 2
n = 4
Step-by-step explanation:
Three equations
Look for x
Look for y
Look for n
__________________
Note that all of these are questions can be answered through isolating the variable.
Let's start with x :
Get x alone :
2(x + 5) = 3x + 1
Distribute :
(2(x) + 2(5))
2x + 10 = 3x - 1
Add 1 to both sides of the equation :
2x + 11 = 3x
Subtract 2x from both sides :
11 = x
x = 11
Next is y :
Isolate y :
3y - 4 = 6 - 2y
Add 4 to both sides :
3y = 10 - 2y
Add 2y to both sides :
5y = 10
Divide 5 from both sides to get y by itself :
y = 2
Lastly is n :
Isolate n :
3(n + 2) = 9(6 - n)
Distribute :
(3(n) + 3(2)) = (9(6) - 9(n))
3n + 6 = 54 - 9n
Subtract 54 from both sides :
3n - 48 = -9n
Subtract 3n from both sides :
-48 = -12n
-12n = -48
Divide -12 from both sides :
n = 4

First, you have to find the relationship between the large triangle and the smaller triangle. 72 is three times as much as 24, so to find x, you would have to find the relationship between 120 and x. So, 120/3 = 40.

Step-by-step explanation:
the line containing the points (-3,k) and (4,8) is parallel to the line containing the points (5,3) and (1,-6) what is the value of k ?
Answer:
The value of k is:
[tex]k=-\frac{31}{4}[/tex]
Step-by-step explanation:
Given
The line containing the points (-3,k) and (4,8) is parallel to the line containing the points (5,3) and (1,-6).
To determine
what is the value of k?
To determine the value of k, the first step we need to do is to find the slope of the line containing the points (5,3) and (1,-6) using the formula
[tex]\mathrm{Slope}=m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here:
[tex]\left(x_1,\:y_1\right)=\left(5,\:3\right)[/tex][tex]\left(x_2,\:y_2\right)=\left(1,\:-6\right)[/tex]now substituting (x₁, y₁) = (5, 3) and (x₂, y₂) = (1, -6) in the formula
[tex]m=\frac{-6-3}{1-5}[/tex]
[tex]m=\frac{-9}{-4}[/tex]
Apply the fraction rule: [tex]\frac{-a}{-b}=\frac{a}{b}[/tex]
[tex]m=\frac{9}{4}[/tex]
Thus, we conclude that the slope of the line containing the points (5,3) and (1,-6) will be:
[tex]m=\frac{9}{4}[/tex]
Importing Tip:
We know that the parallel lines have the same slopes, so the slope of the line containing the points (-3,k) and (4,8) will also be 9/4.Thus, using the slope formula for the line containing the points (-3,k) and (4,8).
[tex]\mathrm{Slope}=m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here:
[tex]\left(x_1,\:y_1\right)=\left(-3,\:k\right)[/tex][tex]\left(x_2,\:y_2\right)=\left(4,\:8\right)[/tex]As we know that the parallel lines have the same slopes.
Thus, the second step we need to do is to substitute m = 9/4 in the slope formula
[tex]\frac{9}{4}=\frac{y_2-y_1}{x_2-x_1}[/tex]
now substituting (x₁, y₁) = (-3, k) and (x₂, y₂) = (4, 8) in the formula
[tex]\:\:\:\frac{9}{4}=\:\frac{8-k}{4-\left(-3\right)}[/tex]
switch sides
[tex]\frac{8-k}{4-\left(-3\right)}=\frac{9}{4}[/tex]
Multiply both sides by 7
[tex]\frac{7\left(8-k\right)}{4-\left(-3\right)}=\frac{9\cdot \:7}{4}[/tex]
Simplify
[tex]8-k=\frac{63}{4}[/tex]
Subtract 8 from both sides
[tex]8-k-8=\frac{63}{4}-8[/tex]
Simplify
[tex]-k=\frac{31}{4}[/tex]
Divide both sides by -1
[tex]\frac{-k}{-1}=\frac{\frac{31}{4}}{-1}[/tex]
Simplify
[tex]k=-\frac{31}{4}[/tex]
Therefore, the value of k is:
[tex]k=-\frac{31}{4}[/tex]
VERIFICATION:
As the value of k = -31/4.
So the first line will contain the points:
(-3, -31/4)(4, 8)Finding the slope between (-3, -31/4) and (4, 8) using the slope formula
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here:
[tex]\left(x_1,\:y_1\right)=\left(-3,\:-\frac{31}{4}\right)[/tex][tex]\left(x_2,\:y_2\right)=\left(4,\:8\right)[/tex]so substituting (x₁, y₁) = (-3, -31/4) and (x₂, y₂) = (4, 8) in the formula
[tex]m=\frac{8-\left(-\frac{31}{4}\right)}{4-\left(-3\right)}[/tex]
Apply rule: [tex]-\left(-a\right)=a[/tex]
[tex]m=\frac{8+\frac{31}{4}}{4+3}[/tex]
Add the numbers: [tex]4+3=7[/tex]
[tex]m=\frac{8+\frac{31}{4}}{7}[/tex]
[tex]m=\frac{\frac{63}{4}}{7}[/tex] ∵ [tex]8+\frac{31}{4}=\frac{63}{4}[/tex]
Apply fraction rule: [tex]\frac{\frac{b}{c}}{a}=\frac{b}{c\:\cdot \:a}[/tex]
[tex]m=\frac{63}{4\cdot \:7}[/tex]
[tex]m=\frac{63}{28}[/tex]
Cancel the common factor: 7
[tex]m=\frac{9}{4}[/tex]
So, the slope of the line containing the points (-3,k) and (4,8) is m = 9/4. It means both lines have the same slopes. Hence, they are parallel.
Therefore, we conclude that the value of k = -31/4 is true.

Apple, carrot, and celery juices are mixed in a ratio 3 : 1 : 2. The amount of appe juice is 33 millimeters.
a) How much more apple juice is used in the mixture than carrot juice?
b) What is the total amount of the mixture?
Answer:
A) 3 times more apple juice is used than carrot juice aka 22 more millimeters
B) 66 millimeters
Step-by-step explanation :
3 : 1 : 2 aka 33 : 11 : 22
You have the ratio, so you just have to divide 33/3 and you know you have to multiply that awnser times the other ratios.
So...
33/3 = 11
3 x 11 = 33
1 x 11 = 11
2 x 11 = 22
So the ratio is 33 : 11 : 22
Then, A is asking you how much more apple juice than carrot juice, so subtract ( amount of apple juice - amount of carrot juice )
33 - 11 = 22 millimeters more apple juice than carrot juice
Then, B is asking you how much juice is there in total. So just add all the juices together....
33+22+11 = 66
So 66 milimeters of juice all together
(a) The apple juice is 22 ml more than the carrot juice.
(b) The total amount of the mixture is 66 ml.
Ratio:Important information:
The ratio of Apple, carrot, and celery is 3 : 1 : 2.Amount of apple juice is 33 ml.(a)
Let the quantity of Apple, carrot, and celery is 3x, x, 2x respectively.
[tex]3x=33[/tex]
[tex]x=11[/tex]
Difference between Apple and carrot juice is:
[tex]3x-x=2x[/tex]
[tex]3x-x=2(11)[/tex]
[tex]3x-x=22[/tex]
Therefore, the apple juice is 22 ml more than the carrot juice.
(b)
The total amount of the mixture is:
[tex]3x+x+2x=6x[/tex]
[tex]3x+x+2x=6(11)[/tex]
[tex]3x+x+2x=66[/tex]
Therefore, the total amount of the mixture is 66 ml.
