Which inequality represents the solution to the inequality below? 2/3m + 3 < m - 4 A. m < 21. B. m < 18. C. m > 21. D. m > 18.
Answer:
m > 21
Step-by-step explanation:
Given the inequality expression
2/3m + 3 < m - 4
Multiply through by 3
2/3 m * 3 + 3(3) < 3(m-4)
2m+9 < 3m-12
Collect the like terms
2m - 3m < -12 - 9
-m < -21
Multiply through by -1
-1(-m)>-1(-21)
m > 21
Hence the required solution is m > 21

AB is a midsegment of trapezoid DEFG what is x?
Answer:
D. 2
Step-by-step explanation:
DEFG is a trapezoid and AB is its Midsegment.
Therefore,
[tex]AB =\frac{1}{2}(DG + EF) \\ \\ 12 = \frac{1}{2} (5x - 4 + 8x + 2) \\ \\ 12 \times 2= (13x - 2) \\ \\ 24 = 13x - 2 \\ \\ 24 + 2 = 13x \\ \\ 26 = 13x \\ \\ x = \frac{26}{13} \\ \\ x = 2[/tex]
Model with mathematics. Hamid has read 60 pages of the book
he will be using for a book report. If he reads 45 pages per hour, how
many hours will it take him to read at least 375 pages of the book?
Define a variable, and then write and solve an inequality to represent
this situation. Graph the solution on a number line.
Answer:
Hamid will take 8 hours and 20 minutes to read 375 pages of the book.
Step-by-step explanation:
Given that Hamid has read 60 pages of the book he will be using for a book report, if he reads 45 pages per hour, to determine how many hours will it take him to read at least 375 pages of the book the following calculation must be done:
375/45 = X
8.3333 = X
0.333 x 60 = 20
Thus, Hamid will take 8 hours and 20 minutes to read 375 pages of the book.
The vertex of this parabola is at (2,-4). When the x value is 3, the y value is -1. What is the coefficient of the squared expression in the parabolas equation?
A.1
B.-2
C.5
D.3
Answer:
the coefficient of the squared expression in the parabolas equation: D. 3
Step-by-step explanation:
y = a (x-h)² + k parabola equation
y=-1 and x=3 vertex(h,k): (2,-4)
-1 = a * (3-2)² + (-4)
-1 = a - 4
a = -1 + 4 = 3
equation: y = 3 * (x-2)² -4

Solve the equation for the value of x,
-4x=36
Please show your work, thank you.
Answer:
x = -9
Step-by-step explanation:
First,Add 4 to both sides
-4x-4+4=36-4+4
Then,simplify
-4x=36
divide both sides by -4
-4x/-4 = 36/-4
Lastly simplify it to get your answer!

When solving -1/8 (x + 35) = - 7, what is the correct sequence of the operations?
1. multiply each side by -1/8, add 35 to each side
2. multiply each side by -1/8, subtract 35 from each side
3. multiply each side by -8, subtract 35 from each side
4. multiply each side by -8, add 35 to each side
Answer:
The correct option is 3.
Step-by-step explanation:
By multiplying each side by -8, you can get rid of the fraction. Then by subtracting 35 from both sides, you get what is x.

The heights, in inches, of five players on a basketball
team are 68, 70, 76, 71, and 70. What is the mean
height, in inches, of these players?
A)76
B)72
C)71
D)70
Answer:
C) 71
Step-by-step explanation:
To find the mean you must first add all the numbers:
68 + 70 + 76 + 71 + 70 = 355.
After that you divide the number you got by how many numbers are in the set.
There are five players so we divide the number by 5
355/5 = 71
Therefore, it is 71.
