X= y(d-b) over a-c would be the answer
Its saying that every 2 years the students decreases by 30 such as in 1990 the number of students in an large urban high school is 3490.In 1992 the number of students was 3460 and keep decreasing every 2 years 30 comes off.
The easiest way to move faster is to:
Years=The Number Of Students
2006=2200
2008=2170
2010=2140
2012=2110
2014=2080
2016=2050
But here is the tricky part the question said 2017 it an odd number so we have half of 30 because 30 comes of every 2 years but its the 1st year so it half of the 2 years and half of 30 students so this equals to:
2017=2035
The definition of the interior angles of a triangle states that
interior angles of a triangle add up to 180º.
This means we can find the measure of <CED:
<C
ED + <E
CD + <C
DE = 180º
<C
ED = 180º - <E
CD - <C
DE
<C
ED = 180º - 43º - 35º
<CED = 102º
By the definition of vertical angles states that a pair of vertical angles are congruent.
This means <C
ED = <A
EB
If <C
ED = 102º
Then
<AEB = 102º
By definition of the interior angles of triangles:
<AEB + <EBA + <BAE = 180º
<AEB = 102º
<EBA = 18º
102º + 18º + <BAE(<A) = 180º
<BAE = 180º - 102º - 18º
<BAE = 60º
<BAE is another way to say <A
<span>
m∠A = 60º</span>
First you would subtract 2 to get d/3 by itself. On the left side you would have h-2 and one the right d/3 (h-2=d/3). Then you divide by 3 to get d by itself. So the answer is h/3-2/3=d
