Answer:
12
Step-by-step explanation:
you subtract the ordered pairs on the sides. then the ones on the top and bottom. then you add all of the sides
<u>27 = 6x + 4y </u>= 1 7/20 = 3 4/5<u>
</u>20 = 2x + 5y<u>
</u>
For 33 Hours, It is = $252.45
Now, for 1 Hour, It is 252.45 / 33 = 7.65
Now, For 36 hours, It would be: 7.65 * 36 = 275.4
In short, Your Answer would be: $275.4
Hope this helps!
Answer is A. first one...
P = -3
G = 3
P = -G = -(3) = -3
1y - 1/x = 1/60 = x*y =60 = x=60/y
3y - 2(60/y) = 6
3y^2-120=6y
3(y^2-40-2y) =0
y^2-40-2y=0
y = 7.4
3(7.4)-2x=6
22.2-2x = 6
2x = -16.2
x = -8.1
