Answer:
Step-by-step explanation:
1. x = y-4
0 = y - 4 -x
4 = y - x
2. 2x+4y = 10
x+4y = 5
x+y = 5/4
Answer:

Step-by-step explanation:
<u>Let </u>
x = 3.777....... (1)
<u>Then </u>
10x = 37.777..... (2)
Subtracting (1) from (2)
10x - x = 37.7777..... - 3.77777.......
9x = 34
Dividing both sides by 9
x = 34 / 9
x =

Answer:
$1.72 per cookie.
Step-by-step explanation:
First things first, subtract the amount of cupcake cost (2.75)
44.03 - 2.75 = 41.28.
Next we add up the amount of cookies he ordered.
8 + 16 = 24
Now we divide 41.28 (the cost minus the cupcake) by 24 (the amount of cookies) to get the amount per cookie.
41.28 ÷ 24 = 1.72
Therefore the answer is 1.72 per cookie.
