Answer:
24$
Step-by-step explanation:
96 x 2 =192
192$ made by 8 students
"If each of the students sold the same number of tickets,"
192/8=24
24$ per student
I would immediately reduce this by div. every term by -2:
x^2 + 8x + 22 = 0
Next, I'd "complete the square:"
x^2 + 8x + (4)^2 - (4)^2 + 22 = 0
(x + 4)^2 - 16 + 22 = 0, so that (x+4)^2 + 4 = 0.
Then sqrt( (x+4)^2 = sqrt(-4)
x+4 = plus or minus i*2
x = -4 plus or minus i*2 (answer)
Answer:
8
Step-by-step explanation:
1) let’s take the original number as “x”
So
3x=28-0.5x
Lol don’t worry I’ll show you how I got that
So it says 3 times a number. That tells me my number, X is multiplied by 3 so I have
3x so far
Next it says “is equal to”, this tells me my number 3x is equal to something so I have this now:
3x=
After that it says “half of a number” so I know I will have 0.5x subtracted from 28. Since it says subtracted from 28 that means my number will be subtracted from 28, not the other way around so
3x=28-0.5X
Now I can solve this by bringing “-0.5” to the left.
3x+0.5x=28
3.5x=28
Divide both sides by 3.5 and
X=8
1. 37 degree. A triangle has 180 there is a right angle 90 and then c is 53 which leaves 37 for a
Answer: b = 1850 - 120w
Step-by-step explanation:
Let w represent the number of weeks for which the books are purchased.
They are being purchased at a steady rate of 120 books per week. This means that the number of books purchased after w weeks would be 120w.
The total number of algebra textbooks that she had initially is 1850
If b represents the number of books left after w-weeks of sales, then the linear function that models the number of books left after w weeks would be
b = 1850 - 120w
