Answer:
a = 27
b = 38
c = 19
Step-by-step explanation:
a + b + c = 84
b = 2c
a = 8+c
8+c +2c+c = 84
4c + 8 = 84
4c = 76
c = 19
b = 2(19) = 38
a = 8 + 19 = 27
Answer:$1.33
Step-by-step explanation: What I did is I subtracted the 46 dollars in donations from the total they raised on day 1 to get the amount for just the cookies $150. Then I added the amount of the 2 total of cookies sold = 200. Then, I took the amount of cookies sold and divided it by the amount they made selling the cookies = 1.33. 200 ÷ 150 = 1.33

4000 divide by 160 to get the cost of each book
4000 / 160 = 25
So that's £25 per book, multiply that by two because they gave two away which is £50 so they lost £50
Answer:
d = 3(h - 2)
Step-by-step explanation:
h = d/3 + 2
taking 2 to the right hand side
h - 2 = d/3
multiplying both sides by 3
3(h - 2) = d
therefore
d = 3(h - 2)
