Answer:
It will take her 10.5 hours to read the book
Step-by-step explanation:
She averages 16 pages every 30 minutes. If you take 336 and divide it by 16, you get 21 hours. But since she is reading 16 pages every half hour, that wouldn be correct. If it is asking how many hours it will take her to read the book, you have to take 16 and multiply it by 2. Then you get 32. Then, do the equation again. 336 divided by 32 is 10.5. So, if she reads the entire book in one go, it will take her 10 and a half hours to read the entire book, or 10.5.
Answer:
infinite solutions
Step-by-step explanation:
4x+4(3x+7) = 8(2x-3) +52
Distribute
4x+12x+28 = 16x-24+52
Combine like terms
16x+28 = 16x +28
Subtract 16x from each side
16x-16x+28 = 16x-16x +28
28=28
This is true, so there are infinite solutions
Answer:
C) 14
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 6 to both sides:
3x - 6 (+6) = 36 (+6)
3x = 36 + 6
3x = 42
Next, divide 3 from both sides:
(3x)/3 = (42)/3
x = 42/3
x = 14
c) 14 is your answer.

Answer:
Step-by-step explanation:
Given: Perimeter of base of a pyramid = 12.8 m
Height of the pyramid = 12.5 m
To find: volume of a pyramid
Solution:
Perimeter of base of a pyramid = 12.8 m
As base of the pyramid is a square,
12.8 = 
side of a square = 
Area of a square (A) = 
Height of the pyramid (h) = 12.5 m
Volume of the pyramid = 
Answer:
Slope is 2/15.
Step-by-step explanation:
To find slope, equation should be written in y- intercept form.
y=mx + b, m is a slope.
(2/3)x -5y =10
5y = (2/3)x - 10
y=(2/15)x -2
Slope is 2/15.
