Answer:
B: 15 hours
Step-by-step explanation:
Since Dara spends 2 hours reading 72 pages, we can conclude that she spends 1 hour reading 36 pages.
Since we are finding how long it would take for her to read 540 pages, we would divide 540 by 36, which is 15.
Answer:
c. 4y -x = 8
Step-by-step explanation:
Each of the equations can be put into slope-intercept form (solved for y) as follows:
a: y = 4x +9
b: y = 4x -8
c: y = (1/4)x +2
d: y = 4x -4
___
The equations containing the term "4x" all describe parallel lines. The equation containing (1/4)x describes a line that intersects the given line. It is not parallel to the others.
Answer:
u take the 3.0 and then x it by 3 that should be the answer
Step-by-step explanation:
It is important because it is more easy to do your work of math
