Answer:
Step-by-step explanation:
1/4x + 1/2x + 1/4x = 360
4(2/4x + 1/2x = 360)
2x + 2x = 1440
4x = 1440
x = 360
1/4(360)= 90 Clermonth
1/2(360)= 180 Central
1/4(360)= 90 other schools
9,6^2+18,8^2=X^2
92,16+353,44=X^2
X^2=445,6
X=21
Answer:

Step-by-step explanation:
since
,

4 is a coefficient and X and Y are variables so the -110 is the constant so there for the answer is D
