OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.
The correct answer is D) 192.
Hope this helps

26 x 3.14 = 81.64 in. The circumference can by found by multiplying pi by the diameter of the circle.
Answer:
x = 2
Step-by-step explanation:
Any lower base angle is supplementary to any upper base angle, then
51x + 3 + 75 = 180
51x + 78 = 180 ( subtract 78 from both sides )
51x = 102 ( divide both sides by 51 )
x = 2
