Answer:
the equation to use would be D (255-20(5) = ?). To solve, first multiply 20 and 5 and you would get 100 so the equation would be 255 - 100 = ? Then you would subtract 100 from the 255 to get $155 left. To solve for 7 weeks you would replace the 5 in the equation with 7 so your equation would be 255 - 20(7) = ? Next you would multiply 20 and 7 to get 140. the equation would then be 255 - 140 = ? Subtract 140 from 255 and you would get 115. So after 7 weeks she would have $115 left in her account.
A= 3,3
B= -2,3
C=-1,-1
D=1,-3
Answer:
Their houses are apart by 
i.e. 
.
Step-by-step explanation:
We have that,
Omari and Daisy lives on the same street as their school.
It is given that,
Omari lives 
= 
= 
blocks west of the school.
Dasiy lives 
= 
blocks east of the school.
Thus, the number of blocks by which their houses are apart = + = 
=
Hence, their houses are apart by i.e. .
Of course not! Imagine a rectangle with sides 3ft by 6ft. It is not a square, since its sides are unequal.
