How do I solve this algebraically?
2-6lnx= 10
Answer:
Work it like a normal algebra problem to get ln x on one side. Then use a calculator or log tables.

Hadley earned 8 more points on her test than Adam earned. Their points add up to 162. How many points did each student earn ?
Answer:
Adam - 77 / Holly - 85
Step-by-step explanation:
x + (x + 8) = 162
2x + 8 = 162
2x = 154
x = 77
x = Adam
x + 8 = Holly
Therefore, Adam - 77 / Holly - 85.

Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 – 0.2x = 9.1 9.1 – 10 = 0.2x To prepare for his mountain biking trip, Rhyan bought four tire patches. Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining. Which equations could you use to find the price of one tire patch? Select all that apply. 4x – 1.9 = 22.2 4x – 22.2 = 1.9 4x + 1.9 = 22.2 4x + 22.2 = –1.9 22.2 – 4x = 1.9
Given:
Different equations are given.
Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.
To find:
The equation which gives a different value of x than the other three.
To find the equations that could you use to find the price of one tire patch.
Solution:
In option A,
[tex]9.1 = -0.2x + 10[/tex]
[tex]0.2x= 10-9.1[/tex]
[tex]0.2x= 0.9[/tex]
Divide both sides by 0.2.
[tex]x=\dfrac{0.9}{0.2}[/tex]
[tex]x=4.5[/tex]
Similarly,
In option B,
[tex]10 = 9.1 + 0.2x[/tex]
[tex]0.9= 0.2x[/tex]
[tex]4.5=x[/tex]
In option C,
[tex]10-0.2x = 9.1[/tex]
[tex]-0.2x = -0.9[/tex]
[tex]x = 4.5[/tex]
In option D,
[tex]9.1 – 10 = 0.2x[/tex]
[tex]-0.9 = 0.2x[/tex]
[tex]-4.5 = x[/tex]
Since option D has difference solution, therefore the correct option is D.
Let price of one tire patch be x.
So, price of 4 tire patches = 4x
Remaining amount in Rhyan's gift card = $1.90
Total amount = $22.20
Price of 4 tire patches + Remaining amount in gift card = Total amount
[tex]4x+1.9=22.2[/tex]
It can be written as
[tex]4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9[/tex]
Therefore, the correct options are C and E.
Answer:
c and e the last and second to last one

Answer:
w(15)=112.5
Step-by-step explanation:
All you have to do is put the number in the parentheses in the place of the variable, which in this case is h, and perform the prescribed operation.
In this case, you make the equation w(15)=7.5(15) which you can rewrite as
w(15)= 7.5×15, which gives . you 112.5 as the product.

HURRY Nora tracked variations in temperature for five days to show how much above or below average the actual temperature was. A 5-column table with 1 row titled Degrees Above/Below Average (Fahrenheit). Column 1 is labeled Monday with entry 2.2. Column 2 is labeled Tuesday with entry negative one-half. Column 3 is labeled Wednesday with entry negative 1 and one-half. Column 4 is labeled Thursday with entry negative 0.9. Column 5 is labeled Friday with entry 1. A number line going from negative 3 to positive 3. Graph the data on the number line. On which day was the temperature the farthest below average?
Answer:
Wednesday
Step-by-step explanation:
1. First find the position of each variable on the number line.
2. The average temperature is 0 because it is in the center.
3. The answer cannot be Monday because it is above so it is Wednesday.
