Answer:
Stephanie needs 220ft² of more soil to cover the rest of her yard.
Step-by-step explanation:
First add the bags she already has:125ft²+65ft²+<em>x</em>=410ft² --> 190ft²+<em>x</em>=410ft²
Second use the subtraction property of equality: 190ft²-190ft²+<em>x</em>=410ft²-190ft² ---> <em>x</em>=220ft²
25 students participate in after school activities and get home after 7pm
There are a total of 448 students at the Westover Middle school
Out of this 448 students a total number of 38 students participate in after school activities
Out of this 38 students that participate in school activities 13 students do not get home till after school
Therefore the number of students that participate in after school activities and get home after 7pm can be calculated as follows
= 38-13
= 25 students
Hence 25 students participate in after school activities and get home after 7pm

Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=
Also y=
We can not divide with zero.
k-12=0
k=12For k= 12 equations have no solutions.
