Hannah took six quizzes in math. She scored 4 twice, 6 once, and 8 three times. What ja Hannah’s average for the six math quizzes?
Answers
Answer:
Option H. 6⅓
Step-by-step explanation:
Let X be the score.
Let F be the number of scores (i.e the frequency)
From the question given above, the following data were obtained from:
X >>>>>>>>> F
4 >>>>>>>>> 2
6 >>>>>>>>> 1
8 >>>>>>>>> 3
Thus, we can obtain the average as follow:
X >>>>>>>>> F >>>>>>> FX
4 >>>>>>>>> 2 >>>>>>> 8
6 >>>>>>>>> 1 >>>>>>> 6
8 >>>>>>>>> 3 >>>>>>> 24
Summation (FX) = 8 + 6 + 24
Summation (FX) = 38
Summation (F) = 2 + 1 + 3 = 6
The average = summation (FX) /Summation F
The average = 38/6
The average = 6⅓
Therefore, Hannah's average for the six math quizzes is 6⅓.

Answers
Given :
Area of room excluding closet is , [tex]a=235.675\ ft^2[/tex] .
Area of closet is , [tex]b=10.45\ ft^2[/tex] .
To Find :
Area of max's room including the closet .

M is the midpoint of RT. RM = 5x + 9 and MT = 8x - 36. Find x, RM, MT, and RT. = .
Answers
The values of x, RM, RT, and MT are 15, 84, 168, and 84 respectively.
What is a System of equations?simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given a system of equations Where RM = 5x + 9 and MT = 8x - 36.
Since,
M is the midpoint of RT
Thus,
RM = MT
5x + 9 = 8x - 36
3x = 45
x = 15
So,
1) RM = 5x + 9
RM = 75 + 9 = 84
2) MT = 8x -36
MT = 120 - 36 = 84
3) RT = RM + MT
RT = 84 +84 = 168
Therefore, The values of x, RM, RT, and MT are 15, 84, 168, and 84 respectively.

Step-by-step explanation:

Explain how you can write an equation for the given situation in standard form. One number is 5 more than a second number. The product of the two numbers is 891.
A) Let x be the smaller number, and then x+5 is the larger number. This means that x(x+5)=891, which can be rewritten as x^2+5x-891=0
B) Let x be the smaller number, and then x+5 is the larger number. This means that x+(x+5)=891, which can be rewritten as 2x-886=0
C) Let x be the smaller number, and then x+5 is the larger number. This means that x(x+5)=891, which can be rewritten as x^2+5x+891=0
D) Let x be the smaller number, and then x+5 is the larger number, This means that x+5/x=891, which can be rewritten as 890x-5=0
Answers
Answer:
you figure it out
Step-by-step explanation:
Number one is going to be N1
Number two is going to be N2
Product of the two numbers combined is going to be 891
N1= N2 +5
N1 + N2 = 891
(N2+5) + N2 = 891
N2 +5 +N2 =891
2N2 + 5 =891

To find the value of s, you want ot use your algebraic properties to isolate s.
4(2s - 1) = 75 + 12 [distribute by FOIL]
8s-4=75+12 [add]
8s-4=87 [add both sides by 4]
8s=91 [divide both sides by 8]

Use the figure and find PT.
PT = 7x - 24 and TQ = 6x-2
Answers
Answer:
PT= 130
Step-by-step explanation:
Since T is the midpoint of segment PQ,
PT = TQ
7x - 24 = 6x-2
Subtract 6x both sides and add 24 both sides
7x -6x - 24 = 6x -6x -2
x - 24 + 24 = -2 + 24
x= 22
Substitue x into PT
7(22) - 24
154 - 24
PT= 130

How do u write 0.57 repeating as a fraction in simplest form explain the steps please!
Answers
Answer:
57/99
Step-by-step explanation:
let's set up an equation:
x = 0.5757...
set up a second equation so the numbers after the decimal places are equal
100x = 57.5757...
subtract
100x = 57.5757...
- x = 0.5757
99x = 57
divide by 99
x = 57/99
0.57 repeating can be expressed as the fraction 19/33 in simplest form.
We have,
Let x = 0.575757... (with 57 repeatings)
Multiplying x by 100,
100x = 57.575757...
Subtracting the original x from 100x,
100x - x = 57.575757... - 0.575757...
99x = 57
To obtain x, divide both sides by 99:
x = 57/99
Dividing both the numerator and denominator by 3,
x = (57/3) / (99/3)
x = 19/33
Therefore,
0.57 repeating can be expressed as the fraction 19/33 in simplest form.
