The work of a student trying to solve the equation 2(2x − 3) = 6 + 2x + 4 is shown below:
Step 1: 2(2x − 3) = 6 + 2x + 4
Step 2: 4x − 3 = 10 + 2x
Step 3: 4x − 2x = 10 + 3
Step 4: 2x = 13
Step 5: x = 6.5
In which step did the student first make an error and what is the correct step? (4 points)
Group of answer choices
Step 3: 4x + 2x = 10 + 3
Step 2: 4x − 3 = 2 + 2x
Step 3: 4x − 2x = 10 - 3
Step 2: 4x − 6 = 10 + 2x
Answer:
Step 2: 4x - 6 = 10 + 2x
Step-by-step explanation:
2 needs to be distributed to all terms inside the parentheses.
Answer:
Step 2 is wrong, and the right step 2 is 4x − 6 = 10 + 2x
Step-by-step explanation:
The student didn't multiply 2(3) in step 2

Parents of students at a middle school
were randomly selected to participate
in a survey. Forty-two out of 60 parents
who were surveyed support a proposal to
buy new computers. There are a total of
456 parents with students at the middle
school. Which is the best estimate of the
number of those parents likely to support
the new proposal?
A. 182
B. 319
C. 365
D. 438
Answer:
(B). 319
Step-by-step explanation:
[tex]\frac{42}{60}[/tex] = [tex]\frac{x}{456}[/tex]
[tex]\frac{7}{10}[/tex] = [tex]\frac{x}{456}[/tex]
x = [tex]\frac{7*456}{10}[/tex] ≈ 319
The best estimate of the number of those parents likely to support the new proposal is 319. So the option is (B) 319.
What is constant of proportionality?Firstly, there is proportional relationship.
Two values x and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.
The constant k is called constant of proportionality.
Parents of students at a middle school were randomly selected to participate in a survey.
42 out of 60 parents who were surveyed support a proposal to buy new computers.
There are a total of 456 parents with students at the middle-school.
[tex]\dfrac{42}{60} = \dfrac{x}{456} \\\\\\x = \dfrac{42}{60} \times 456\\\\x = \dfrac{7}{10} \times 456\\\\x = 319[/tex]
Therefore, the best estimate of the number of those parents likely to support the new proposal is 319.

How do u solve this?
Answer:
? = 2 Full Answer: 1/2
Step-by-step explanation:
A regular die has only 6 numbers: 1, 2, 3, 4, 5, & 6.
In those numbers, there are 3 odd numbers, and 3 even numbers. This would mean that the probability of getting an odd number would be 3/6.
But to simplify it, 3/6 ALSO equals 1/2
Answer:
1/2 is the answer
Step-by-step explanation:
A die has 6 possible outcomes: 1, 2, 3, 4, 5, 6
Out of these numbers 3 are odd numbers.
P(Event) = Number of favourable outcomes/ Total number of outcomes
P(odd) = 3/6
= 1/2

5x-y=-6
y=-7x+6
find y and x and show work
Answer:
5x-y=-6.............1
y=-7x+6...........2
substituting value of y in equation 1
5x-(-7x+6)=-6
5x+7x-6=-6
12x=0
x=0/12=0
substituting value of x in equation 1
5×0-y=-6
y=6
Consider the quadrilateral shown below that has vertices A, B, C, and D.
Suppose we know the following measurements:
¯¯¯¯¯¯¯¯AB=5.8 cm
¯¯¯¯¯¯¯¯BC=5.4 cm
¯¯¯¯¯¯¯¯¯CD=3.3 cm
¯¯¯¯¯¯¯¯¯AD=6.2 cm
m∠A=27∘
What is the degree measure of ∠C?
m∠C= °
Answer:
C = 25.94°
Step-by-step explanation:
By applying cosine rule in ΔABD,
BD² = AB² + AD² - 2(AB)(BD)cosA
BD² = (5.8)² + (6.2)² - 2(5.8)(6.2)(cos27°)
BD² = 33.64 + 38.44 - 64.08
BD² = 8
BD = √8
By applying cosine rule in ΔBCD,
BD² = BC² + CD²- 2(BC)(CD)cosC
(√8)² = (5.4)²+ (3.3)² - 2(5.4)(3.3)cosC
8 = 29.16 + 10.89 - 35.64cosC
35.64cosC = 32.05
cosC = 0.89927
C = [tex]\text{cos}^{-1}(0.89927)[/tex]
C = 25.94°
By using cosine formula of triangles we got that measure of ∠C is 25.94 °
What is a quadrilateral ?Quadrilateral is a closed shape with 4 sides and 4 corners.
Here given that
AB=5.8 cm
BC=5.4 cm
CD=3.3 cm
AD=6.2 cm
and [tex]\angle A=27[/tex] °
in [tex]\triangle \mathrm{ABD}[/tex]
Applying cosine formula
[tex]$$\begin{aligned}&\mathrm{BD}^{2}=\mathrm{AB}^{2}+A D^{2}-2(\mathrm{AB})(\mathrm{BD}) \cos A \\\\&\mathrm{BD}^{2}=(5.8)^{2}+(6.2)^{2}-2(5.8)(6.2)\left(\cos 27^{\circ}\right) \\\\&\mathrm{BD}^{2}=33.64+38.44-64.08\\ \\&\mathrm{BD}^{2}=8 \\\\&\mathrm{BD}=\sqrt{8}\end{aligned}$$[/tex]
Now in [tex]\triangle B C D[/tex]
Applying cosine formula
[tex]$$\begin{aligned}&\mathrm{BD}^{2}=\mathrm{BC}^{2}+\mathrm{CD}^{2}-2(\mathrm{BC})(\mathrm{CD}) \cos \mathrm{C} \\\\&(\sqrt{8})^{2}=(5.4)^{2}+(3.3)^{2}-2(5.4)(3.3) \cos \mathrm{C} \\\\&8=29.16+10.89-35.64 \cos \mathrm{C}\\ \\&35.64 \cos \mathrm{C}=32.05\\ \\&\cos \mathrm{C}=0.89927 \\\\&\mathrm{C}=\cos ^{-1}(0.89927) \\&\end{aligned}$$[/tex]

Answer:
59°
Step-by-step explanation:
The law of cosines tells you ...
h² = f² +g² -2fg·cos(H)
Solving for angle H gives ...
H = arccos((f² +g² -h²)/(2fg)) = arccos(725/1400) ≈ 58.811°
