X=skirt
y=sweater
z=shoes
x+y+z=165
y=8/7x
z=x+11
plug it in
x+(8/7x)+(x+11)=165
2x+8/7x=154
22/7x=154
x=49
y=56
z=60
a skirt cost $49, a sweater cost $56, and a pair of shoes cost $60
-14W + 35. Can’t simplify any further
Answer:
49n^2-70n+25
Step-by-step explanation:
(7n-5)(7n-5)
FOIL it: 49n^2-35n-35n+25
combine like terms: 49n^2-70n+25
Area = 200.96 cm^2
r = square root of area / 3.14
radius r = 7.9967778595084
