Answer:
she spends 9 hours
Step-by-step explanation:
32
3x+1=8x-24
25=5x
x=5
3 times 5 plus 1 is 16 and so the length is 32
comment section:
XM=MY because MN is segment bisector
XM=3x+1=3*5+1=16=MY and since XM+MY=XY 16+16=32
#11
Perimeter:
P = 2(W + L)
P = 2(3.5 + 6.5)
P = 2(10)
P = 20 units
Area:
A = WL
A = 3.5 * 6.5
A = 22.75 square units
x-y =8
x/y=3
=> 3y-y=8
=> 2y = 8
=> y = 4
=> x = 4+8 =12
