LenKa [72]
We know that:

(+)+(-)=(-)

and:

(-)*(+)=(-)

8+(-3)[6+(-6a)]=8+(-3)*6+(-3)*(-6a)=8-18+18a=(-10)+18a

if you have solve for a then:

(-10)+18a=0
18a=10
a= \frac{10}{18}
a=\frac{5}{9}

Alexndra earns $125 from her paper route each month but she spends about $20 each month on personal expenses.To pay for a school
Andrei [34K]
It would take Alexandria 8 months to earn the money. 

125-20= 105 monthly earnings after personal expenses 
800/105= 7.6 which rounds to 8.

8x105= 840

Angle MNO is formed by segments MN and NO on the following coordinate grid:
Eva8 [605]

Answer:

I am 90% sure that the answer is M'N'O' is 90*

Step-by-step explanation:

A line segment MN is shown as M = -1,1 and N= -5,4 this makes a diagonal line across the grid. Another line segment NO is shown with O as ordered pair negative 1, 4. Angle MNO is rotated 90 degrees counterclockwise about the origin to form angle M′N′O′. this is where the angles meet, Rotating the shape (or the angles) does not change the degree of the angle of the shape. I am 99% sure that an 90* angle would be formed. but im just in middle school so what do i know?
