The equations are e = 18+12t and a = 45+9t
Adrian will be father along in the book after 4 days. She will be 15 pages ahead of Ethan
Ethan's page number at the beginning of the month = 18
Adrian's page number at the beginning of the month = 45
Pages read by Ethan each day = 12 pages
Pages read by Adrian each day = 9 pages
Let e represent the page of the book that Ethan is on at the end of t days into the month. Let a represent the page of the book that Adrian is on at the end of t days into the month.
Formulating the equation we get the following:
e = 18 + 12t
a = 45 + 9t
Finding the page number of both Ethan and Adrian after 4 days by substituting the values in the equations we get:
e = 18+12(4)
e = 66
a = 45 + 9(4)
a = 81

A successful basketball player has a height of 6 feet 66 inches, or 198 cm. based on statistics from a data set, his height converts to the z score of 3.38. how many standard deviations is his height above the mean
Answer: z-score tells us how many standard deviations either above or below the mean a particular data value is.
There the z-score of the height of basketball player is 3.38. It means his height is 3.38 standard deviation's above the mean.
Set Abe as x
set Bella as y
set Carlos as z
<span>Bella has earned 10 less credits than Abe
y=x-10
</span><span>Carlos has earned two less than double the number of Abe’s credits
</span><span>z=2x-2
</span><span>Altogether, they have earned a total of 136 credits
</span><span>x+y+z=136
replace y with x-10
replace z with 2x-2
x+(x-10)+(2x-2)=136
solve for x
4x-12=136
4x=148
x=37
We now know Abe earned 37 credits
To find how much Bella earned plug in 37 for y=x-10
y=27
To find how much Carlos earned plug in 37 for z=2x-2
z=72
Therefore,
Abe earned 37 credits
Bela earned 27 credits
Carlos earned 72 credits

Answer:
This vector make an angle of 141° with the positive x axis
Step-by-step explanation:
Refer the attached figure
Components of vector :
We are supposed to find What angle does this vector make with the positive x axis
Now ,
So, this vector make an angle of 141° with the positive x axis
Answer:
Step-by-step explanation:
First of all, you have to set up the equation
2x^2 + x -1 = 2 Subtract 2 from both sides
2x^2 + x - 1 - 2 = -2+2 Combine
2x^2 + x - 3 = 0 This factors.
(2x + 3)(x -1 ) = 0
Either
2x + 3 = 0 Subtract 3 from both sides
2x = - 3 Divide by 2
2x/2 = - 3/2
x = - 3/2 which you already know
or
x - 1 = 0 Add 1
x - 1 + 1 = 1
x = 1
the other answer is x = 1
