Answer:
a) Angle XBC = 55° because it's a corresponding angle
AXY = XBC
b) 180° - (55° × 2) = 70°
3/4 = x / 340....3 to 4 students = x to 340 students
cross multiply
(4)(x) = (3)(340)
4x = 1020
x = 1020/4
x = 255 <==
or this way.....
3 out of 4 students.....3/4 = 75%
so 75% of 340 = 0.75(340) = 255 <=
Answer:
y=-2x/3+3
Explanation:
2x+3y=9
-2x -2x
3y=-2x+9
3y/3= -2x/3+9/3
y=-2x/3+3
Hope this helps!!
