For part A add up all your students then add up all your students that like bike riding and skating (80+90) divide that by the total number of students who took the survey
For Part be put 20+40 over the toatl number of student then simplify
Each edge is 4 feet. To find volume, you do length x width x height. A cube has all equal sides. 4x4x4=64
Answer:
2y-4-6y-12=4
-4y=20
y= -5
Step-by-step explanation:
because (y+2)(y-2)=y^2-4
so we have the step to let the every part have the same denominator y^2-4
2(y-2)/(y+2)(y-2) -6(y+2)/(y-2)(y+2)=4/(y-2)(y+2)
the denominators are the same so the equality .we just need the part over be the same 2y-4-6y-12=4
y= -5
Answer:
3/-2
Step-by-step explanation:
The third table is the answer.
x=-5 => y=-5-6=-11
x=-8 => y=--8-6=-14
y=-7 => y=-7-6=-13
