Answer: lisa's sister is 3
Step-by-step explanation:12-6 is 6 then 6/2 is 3 so the check lets do it backwards 3*2 is 6 +6 because Lisa is 6 years older than twice her sister's age
The equation is y = 2x + 6. Then the age of her sister will be 3 years old.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Lisa is six years older than her younger sister. Lisa is twelve years old.
Let y be the age of Lisa and 'x' be the age of her sister. Then the equation is given as,
y = 2x + 6
If the age of Lisa is 12. Then the age of her sister is calculated as,
12 = 2x + 6
2x = 12 - 6
2x = 6
x = 6 / 2
x = 3
The equation is y = 2x + 6. Then the age of her sister will be 3 years old.

Solve The Two Equations for x.
Answer:
x = 7, x = 5
Step-by-step explanation:
[tex]\frac{3x+3}{8}[/tex] = 2x - 11 ( multiply both sides by 8 to clear the fraction )
3x + 3 = 16x - 88 ( subtract 3x from both sides )
3 = 13x - 88 ( add 88 to both sides )
91 = 13x ( divide both sides by 13 )
7 = x
--------------------------------------------------------------
[tex]\frac{4x-6}{7}[/tex] = 2 ( multiply both sides by 7 )
4x - 6 = 14 ( add 6 to both sides )
4x = 20 ( divide both sides by 4 )
x = 5
3x + 3 / 8 = 2x - 11
Multiply both sides by 8
8 × ( 3x + 3 / 8 ) = 8 × ( 2x - 11 )
3x + 3 = 16x - 88
Add both sides 88
3x + 3 + 88 = 16x - 88 + 88
3x + 91 = 16x
Subtract both sides 3x
3x - 3x + 91 = 16x - 3x
91 = 13x
Divide both sides by 13
91 ÷ 13 = 13x ÷ 13
7 = x
x = 7
_________________________________
4x - 6 / 7 = 2
Multiply both sides by 7
( 4x - 6 / 7 ) × 7 = 2 × 7
4x - 6 = 14
Add both sides 6
4x - 6 + 6 = 14 + 6
4x = 20
Divide both sides by 4
4x ÷ 4 = 20 ÷ 4
x = 5

some patients participated in a clinical trial for a new drug to treat osteoporosis. A patient is selected at random. The probability that the patient had no change in his bone mass density is 7/13, the probability that he had a slight reduction in his bone mass density is 1/k and the probability that he had a significant reduction in his bone mass density is 1/2k. Find the value of k
Answer:
k = 3.9
Step-by-step explanation:
Since the three possible outcomes are given. Therefore, the sum of all the probabilities of the three possible outcomes will be equal to one:
[tex]\frac{7}{13} +\frac{1}{k}+ \frac{1}{2k} = 1 \\\\\frac{1}{k} \frac{1}{2k} =1-\frac{7}{13}\\\\\frac{3}{2k} \frac{5}{13}\\\\2k = \frac{(13)(3)}{5}\\\\k = \frac{39}{(5)(2)}\\[/tex]
k = 3.9

Describe the trend/correlation
shown in the scatter plot below
Answer:
Negative correlation.
Step-by-step explanation:
Negative correlation means that as x increases, y decreases
Positive correlation means that as x increases, y also increases.
No correlation means that neither of the two above cases happens.
In the graph, we can see that on the right (when x is negative) the general y values are larger.
As x increases, the y-values decrease.
(Particularly, we could adjust these data with a linear equation with a negative slope)
Then this is a negative correlation.

A cube has edge lengths of 11 ft. What is the volume of the cube?
Answer:
1331 ft³
Step-by-step explanation:
The volume of a cube = (edge length)³
From the above question,
Edge length = 11 ft
The volume of the cube = (11 ft)³
= (11 ft × 11 ft × 11 ft)
= 1331 ft³
The volume of the cube = 1331 ft³
 A set of measurements is taken and recorded and the table shown.
does the data in the table have a constant rate of change or a constant multiplier, and what is its value?
A.
Constant rate of change of 1.2
B.
Constant multiplier of 1.2
C.
Constant rate of change of 1.5
D.
Constant multiplier of 1.5
Answer;
The correct answer here is constant multiplier of 1.5
Step-by-step explanation:
To get the constant multiplier, we have to take a look at the y values
subsequent y values were obtained by multiplying the preceding y value with a term
So we have it that;
3.6/2.4 = 5.4/3.6 = 8.1/5.4 = 1.5
The correct answer here is constant multiplier of 1.5

The volume of a cylinder is 117.1 cubic feet, and its height is 15 ft. Find the diameter of the base of the cylinder.
Answer:
3.15 ft
Step-by-step explanation:
V
Volume of a cylinder: πr²h. Solving for r², we get r² = ---------
πh
Here, we get r² = (117.1 ft³) / (3.14·15 ft) = 2.48 ft² and r = √(2.48 ft²), or
1.58 ft, so that the diameter is 2r, or 3.15 ft
The diameter of the base of the cylinder is 3.15 ft.

The two triangles are similar, so [tex]\triangle{NPO} \sim \triangle{YZO}[/tex].
Vertex N matches up with vertex Y.
Vertex P matches up with vertex Z.
Vertex[tex]\frac{NO}{YO}=\frac{1}{4}\\\\\frac{x}{124}=\frac{1}{4}\\\\4x=124\\\\x=31[/tex] O matches up with itself.
Corresponding sides are in proportion. To find the proportion between the two triangles, you use known sides from each.
[tex]\frac{NP}{YZ}=\frac{23}{92}=\frac{1}{4}[/tex] meaning the small triangle is 1/4 the size of the large one.
To find x , notice that it is side NO which corresponds to side YO from the large triangle.
