Answer:
The answer would be B.) 5x - 3y = 30
Answer:
1 ) 180 - 71 = 109
2) 5x +x = 180 ; 6x = 180 ; x = 180/6 = 30
3) 90
4) x + 6x+8 + x+12 = 180 ; 8x + 20 = 180 ; 8x = 160/8= 30
5) 180 -110 = 70
6) m = 180- 119 = 61
7) 90
8) 11y - 36 = 63 ; y = 99/11 = 9

(Q7) 180
(Q8) 2x+x = 3x = 90 ; x = 90/3 = 30
(Q15) 157
(Q16) 5x + 4 + (x-2) + (3x+7) = 180
9x +9 = 180 ; x = 171 / 9 = 19
I hope im right!!

Answer:
Dylan delivered 140 parcels on Wednesday.

On Wednesday:
On Wednesday, he delivered x parcels.
Thursday:
10% more than Wednesday, so 100 + 10 = 110% of x = 1.1x
Friday:
50% pless than on Thursday, so 100 - 50 = 50% of 1.1x = 0.5*1.1*x.
THis is equals to 77. So
