Answer:
Undefined
Step-by-step explanation:
This is horizontal line, so the slope is undefined.
The formula for the area of a trapezoid is A = a+b/2 * h. So just plug in the dimensions.
A = 5 + 3/2 * 5
A = 8/2 * 5
A = 4 * 5
A = 20 units²

Go over the x axis up 5 and over the y axis left 1
the parallel line is 2x+5y+15=0.
Step-by-step explanation:
ok I hope it will work
soo,
Solution
given,
given parallel line 2x+5y=15
which goes through the point (-10,1)
now,
let 2x+5y=15 be equation no.1
then the line which is parallel to the equation 1st
2 x+5y+k = 0 let it be equation no.2
now the equation no.2 passes through the point (-10,1)
or, 2x+5y+k =0
or, 2*-10+5*1+k= 0
or, -20+5+k= 0
or, -15+k= 0
or, k= 15
putting the value of k in equation no.2 we get,
or, 2x+5y+k=0
or, 2x+5y+15=0
which is a required line.
SO from what I did was...
Since 24 x 3 = 72 , I did the same to 16.
16 x 3 = 48
But because instead of their being 3 teachers there is 1... What I did is just was to divide 48 / 2 which gave me the answer of 24...
So what I think the answer is...
There are 72 boys, 24 girls, and 1 teacher...
Unless I am just dumb and it would be 48 girls, but I think I did it right.
I hope I was able to help out.
