1. (4,1) is not a solution because when u sub it into the equation, it does not come out correct. It would be correct if it was (1,4).
2. C = 2.50d.....where C is the cost and d is the number of drinks bought. And if u pick any number for d, then u can solve for the cost (C).

Answer:
A =315 cm^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) *h
where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 13+29) *15
A = 1/2 (42)* 15
A =315 cm^2
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
~~~~~~~~Next page~~~~~~~~~~
(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!!
