Convert feet to inches
100ft=12*100 =1200 inches
convert 24 and 3/8 to improper fraction
24 and 3/8=24+3/8=192/8+3/8=195/8
195/8 times number of pieces=1200
times bothsides by 8/195 to clear fraction (195/8 times 8/195=1560/1560=1)
number of pieces=9600/195
number of pieces=49.23someting
she can cut 49 complete pieces and 1 partial piece

she cut 49 pieces
Answer:
neither, would technically be intersecting lines tho
Step-by-step explanation:
So to begin, substitute all of the variables in for their corresponding value.
X=3
Y=-5
Z=-1
2XY+6YZ^2
2(3)(-5)+6(-5)(-1^2)
-30+-30
-60
Hopefully this is what they're asking for!
