Answer:
Yes
Step-by-step explanation:
"data includes which problems where attempted, the time at which each problem was attempted, the answers the student submitted and whether they were correct, the duration the student was working on each problem, whether each assignment was completed on time and the completion percentage for each assignment" (paragraph 4).

1. -18 +15x = 3(4x-6) + 3x
-18 + 15x = 12x - 18 + 3x
-18 + 3x = -18 + 3x
3x = 3x
x = All Real Numbers (because we don't know what x is since the equation is 3x = 3x, we can assume that it is all "real" numbers)
2. -10 + 5x = 5(x - 3) + 5
-10 + 5x = 5x - 15 + 5
-10 = -10
Answer Undefined (because the x coefficients canceled out, we don't know what x even is, so we can claim it as undefined.)
Answer: 14
Step-by-step explanation:
We want the smallest value so:
we know 5n is the square of a number, so
n = 5a^2, so a > 1
we know 75np is the cube of a number, so
p= 3^2a = 9a
Now, n+p = 5a^2 + 9a = a [5a+9]
The smallest value would be when a=1
Therefore when you plug it in , n+p = 5+9 = 14
Hopefully that helped :)
Answer:
B
Step-by-step explanation:
This is pretty easy because you'll only have one variable.
First draw a box and label your width as 12 cm, your length as 2w (because it is twice the length of the width), and your height as 2w+10(beacuse it twice the width{2w} plus 10cm)
Then, substitute 'w' for the widths measurement(12)
So, 2w becomes 2 x 12 or 24cm and 2w+10 becomes (2 x 12) +10 or 24+10 which is 34 cm
then just simply use the volume formula of a box which is V=lwh or length x width x height, so its 12 x 24 x 34 which equals 9,792 cm^3
Answer: y= 2x + 3
Step-by-step explanation:
Point slope formula: y = mx + b
Since the given point is (8,19), 19 is our y, and 8 is our x. Since the slope is 2, our m is 2.
Sub in values.
y = mx + b
19 = 2(8) +b
19 = 16 + b
b = 19-16
b = 3
Now that we have m and b, we can make the equation.
y = mx + b, sub in 2 for m and 2 for b
y = 2x + 3
19 = 2(8) + 3
19 = 16 + 3
19 = 19
So the answer is y = 2x+3
