Answer:
17 hours
Step-by-step explanation:
Rachel has already written 10pages, and she expects to write 1page for every additional hour spent writing. How many hours will Rachel have to spend writing this week in order to have written a total of 27pages?
The illustration can be modelled using the equation
y = 10 + 1(x)
y = 10 + x
Where,
y = total number of pages
x = number of hours
10 = pages already written
If y = 27 pages, find x
y = 10 + x
27 = 10 + x
27 - 10 = x
17 = x
x = 17 hours
Rachel have to spend 17 hours writing this week in order to have written a total of 27pages
Answer:
st = 30 or 270
Or, if assume these are line segments on a straight line, then our answer would be: ST = 3
Combine like terms so combine -2x and x which gives you x=143
Answer: 1 or -1
Step-by-step explanation:
X could equal 1 or -1 because the absolute value makes everything positive.
Answer:
x = 10
Step-by-step explanation:
Sum of all the angle of triangle = 180
71 + 50 + 6x - 1 = 180
71 + 50 -1 + 6x = 180
120 + 6x = 180
6x = 180 - 120
6x = 60
x = 60/6
x = 10
