Step-by-step explanation:
2w+3(2w)=30
8w=30
w=3.75
l=11.25
Her avarage speed in miles per hour is 54
How i solved this was by 135/2.5 and i got 54
I hope this helps!
Aida did not correctly divide by the common factor to get (4+8).
Since this is an improper fraction, you simplify it into a mixed number.
4 goes into 6 1 time. 2 left left over, resulting in 1 2/4. Simplify that into
1 1/2
Given:


To find:
The quadrant in which
lie.
Solution:
Quadrant concept:
In Quadrant I, all trigonometric ratios are positive.
In Quadrant II, only
and
are positive.
In Quadrant III, only
and
are positive.
In Quadrant IV, only
and
are positive.
We have,


Here,
is negative and
is also negative. It is possible, if
lies in the Quadrant IV.
Therefore, the correct option is D.
