Tao wants to check that the expression 3(4x – 6) simplifies to 12x – 18. What is the value when 2 is substituted for x into both expressions? The value of each expression is 2. The value of each expression is 6. The value of one expression is 2, and the value of the other expression is 6. The value of one expression is 6, and the value of the other expression is –6.
Answer:
The value of each expression is 6.
Step-by-step explanation:
3 * 4 = 12 and 3 * 6 = 18
So 3(4x - 6) = 12x - 18
12(2) - 18 = 24 - 18 = 6

How far did each student run?
Answer:
Techincally it would be 5 miles, but if they split the distance and run part of the 5 miles, it would be 5/6 miles.
Step-by-step explanation:
Techincally it would be 5 miles, but if they split the distance and run part of the 5 miles, it would be 5/6 miles.
What is Distance?Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are.
Given, If 6 children run a 5 mile race. They each run the same distance then how far did each student ran.
As all the 6 students running with same distance, they would be far of 5 miles, if they split the distance and run part of the 5 miles, it would be 5/6 miles.
Therefore 5 miles, but if they split the distance and run part of the 5 miles, it would be 5/6 miles.

Two sisters bought together 14 books. One bought 9 books. Which of the following equation represent the number of books bought by the other sister (x)?
Answer:
9+x=14
Step-by-step explanation:
The x represents the other sister and all the books together would equal 14. The other sister got 5 books!
The equation that represents the number of books bought by the other sister is x + 9 = 14.
Here, we have,
given that,
Two sisters bought together 14 books. One bought 9 books.
To represent the number of books bought by the other sister (x) given that the two sisters bought together 14 books and one sister bought 9 books, we can use the equation:
x + 9 = 14
In this equation, x represents the number of books bought by the other sister.
The equation states that the sum of the number of books bought by the other sister (x) and the sister who bought 9 books is equal to the total number of books bought together, which is 14.
Therefore, the equation that represents the number of books bought by the other sister is x + 9 = 14.

Choose the slope-intercept form of 3x + 2y = 5
Answer:
y = -3/2x + 5/2
Step-by-step explanation:
slope intercept form is y = mx + b
so we have to solve the equation for y
2y = 5 - 3x
y = 5/2 -3/2x
or
y = -3/2x + 5/2

Is the sequence arithmetic? If yes, determine the common difference. *
(1 Point)
-14-9, -4, 1, 6, ...
O no, it does not increase or decrease the exact same amount
O yes, d = 5
O yes, d = -5
Answer:
Option 2: Yes, d= 5 is the correct answer
Step-by-step explanation:
An arithmetic sequence is a sequence where the common difference between the consecutive terms is same.
Given arithmetic sequence is:
-14, -9, -4, 1, 6
To check if it is an arithmetic sequence, we have to find the common difference d
[tex]a_1 = -14\\a_2 = -9\\a_3 = -4\\a_4 = 1[/tex]
Now,
[tex]d = a_2-a_1 = -9-(-14) = -9+14 = 5\\d = a_3 - a_2=-4-(-9) = -4+9 = 5\\d = a_4-a_3 = 1-(-4) = 1+4 = 5[/tex]
As the common difference is same, the given sequence is an arithmetic sequence.
Hence,
Option 2: Yes, d= 5 is the correct answer

Answer:
$180 in total!
Step-by-step explanation:
10 + 30 + 30 + 100 + 10 = 180
the uncle and aunt gave their money together, it didn't specify that they each gave 100
Answer:
The total amount of money i have is $180.
Step-by-step explanation:
Given information:
The money i have = $10
Mom gives = $30
Dad gives = $30
Aunt and uncle gives = $100
Now i had another $10
The total amount of money (x) i have is the sum of all money i receive.
x = 10+30+30+100+10
x = 180
Hence , the total amount of money i have is $180.

Which of the following points would be on the graph of the equation y=−4x+6?(−4, −10)(−4, 22)(1, −10)(1, −2)
Answer:
Only the point (-4, 22) is ON THE GRAPH of the equation. Please also check the attached graph.
Step-by-step explanation:
Given the equation
[tex]y=-4x+6[/tex]
Let us substitute all the given points to check which points satisfy the equation.
Substitute (-4, -10) in the equation
[tex]y=-4x+6[/tex]
[tex]-10=-4(-4)+6[/tex]
[tex]-10=16+6[/tex]
[tex]-10=22[/tex]
As the R.H.S ≠ L.H.S, hence (-4, -10) does not satisfy the equation.
Hence, (-4, -10) is NOT ON THE GRAPH of the equation
Substitute (-4, 22) in the equation
[tex]y=-4x+6[/tex]
[tex]22 = -4(-4)+6[/tex]
[tex]22 = 16+6[/tex]
[tex]22 = 22[/tex]
As the R.H.S = L.H.S, hence (-4, 22) satisfies the equation.
Hence, (-4, 22) is ON THE GRAPH of the equation. Please also check the attached graph.
Substitute (1, -10) in the equation
[tex]y=-4x+6[/tex]
[tex]-10=-4(1)+6[/tex]
[tex]-10=-4+6[/tex]
[tex]-10=2[/tex]
As the R.H.S ≠ L.H.S, hence (1, -10) does not satisfy the equation.
Hence, (1, -10) is NOT ON THE GRAPH of the equation
Substitute (1, -2) in the equation
[tex]y=-4x+6[/tex]
-2 = -4(1)+6
-2 = -4 + 6
-2 = 2
As the R.H.S ≠ L.H.S, hence (1, -2) does not satisfy the equation.
Hence, (1, -2) is NOT ON THE GRAPH of the equation
Therefore, from the above analysis, we conclude that only the point (-4, 22) is ON THE GRAPH of the equation. Please also check the attached graph.
3(6d - 24) = 6(12 + 3d)
pls solve i need
3D = 32 or D = (10 2/3)
Step-by-step explanation:
We want to make D only one side so we subtract 3D from the left
Then we slowly make the equation smaller and smaller by adding 24 to each side, multiplying the numbers, then finally getting our answers.
Answer:
No solutions
Step-by-step explanation:
Distribute the 3 to the first set of parentheses:
3(6d - 24) = 6(12 + 3d)
18d - 72 = 6(12 + 3d)
Distribute the 6 to the other set of parentheses:
18d - 72 = 72 + 18d
Subtract 18d from both sides:
-72 = 72
-72 [tex]\neq[/tex] 72
Since -72 and 72 are not equal, there are no solutions
