45 + 35x = 40x
45 = 40x - 35x
45 = 5x
45/5 = x
9 = x <=== they are the same cost at 9 nights
The answer is 24.5
Remember to follow P.E.M.D.A.S
14+2+3(4)-(6.5-3)=
14+2+12-(3.5)=
28-(3.5)=
24.5
Hope it helps
Start by taking the information we know, and write equations to represent the realationships:
1) "1/8 lbs less flour to make bread than to make cookies"

2) "1/4 lb more flour to make cookies than to make brownies:

3) "she used 1/2 lb of flour ro make bread"

From here you can solve for

using back substitution.
Answer:
15.31
Step-by-step explanation:
solve both sides separately
6x+78/67-78x
x cancles out
becomes 84/-11
becomes -7.64 rounded
180+270-567
becomes -117
moves -7.64 to other side (divide by other side)
-117/-7.64
becomes 15.31
Hello,
x= amount of flour that she poured in the canister
there was 5,026 grams of flour, and now: 5,026+x
In the bag there was 4,158, now: 4,158
I says that as a result the mass of the flour in the canister is twice the mass of the flour left in the bag, so:

So, she poured 1,096.67 grams, we subtract this from the initial amount in the bag and we have the answer:
Answer: there is 3,061.33 grams of flour in the bag
