The answer is y = 100
To get this answer, you add 17 to both sides to undo the "minus 17" that is happening on the right side.
83 = y-17
83+17 = y-17+17 ... add 17 to both sides
100 = y
y = 100
Step-by-step explanation:
a) gradient= y2-y1/x2-x1
gradient of AB:
gradient=-4-1/2-3
=-5/-1
=5
gradient of BC:
=-5+4/7-2
=-1/5
b) as the priduct of both gradient is -1 ,both lines are perpendicular.
c) as we have seen lines are perpendicular so it is a right angled triangle.
Answer:
Step-by-step explanation:
all you have to is 8x12 multiplied by 2 since there is 2 rooms which is 192
Must be in the same units
6 ft/ 24 ft (8yds x 3 = 24 ft)

Let's use yards instead
6 ft = 2 yds
so
2 yds/8 yds again is 1/4
