28/x = 40/100
Cross multiply
40x = 28(100)
40x = 2800
Divide both sides by 40
x = 70 students
I THINK ITS C.135 DEGREES
Answer:
x -2y -2=0
Step-by-step explanation:
using the formula, m= ( Y2 - Y1)/( X2-X1)
the gradient is found. the coordinates chosen are (2,0) and ( 0,-1)
the equation of the line is obtained using the formula
y -y1= m(x -x1)
46+19+54= 119, so the answer is 119
It looks like the first 3 are because they all are blank x2.5 but the last one would be 8x2.5=20..
