Let come up with a value to represent 7th graders and 6th graders.
7th=x
6th=y
Y= 0.25x
X+y=135
Plug in 0.25x for Y
X+0.25x=135
X=108 7th graders
Y=27 6th graders
-8, 21, 44
X+y+z=57
Z-x=52
X+y=13
Z=52+x
Y=13-x
X+52+X+13-X=57
X=-8
Z-(-8)=52
Z=44
Y+(-8)=13
Y=21
Answer:
Yes
Step-by-step explanation:
if it's a less than or equal to it goes from the left to the right and has a full dot
Answer:
Step-by-step explanation:
C=9P
P=2(L+W)
C=18(L+W)
C=18(8(12)+7(12))
C=18(96+84)
C=18(180)
C=$3240
So you do not have enough money to enclose the property.
