Answer:
28.21 = 4x + 4.61
Step-by-step explanation:
Since x equals the bags of apples and he bought 4 of them, we would multiply x by 4 like this: 4x
$4.61 were already added to the total cost of $28.21
If we wanted to find out how much each bag cost, we subtract 4.61 from both sides
28.21 = 4x + 4.61
- 4.61. - 4.61
23.6 = 4x
Then, divide both sides by 4
23.6/4 = 4x/4
x = 5.9
Each bag of apples cost $5.90
-2*4=-8
-8 is the correct answer
Answer:
1/15 gal / mile if your numbers are correct
Step-by-step explanation:
1/5 / 15/4 = 1/5 * 4 / 15 = 4/60 = 1/15
Answer:
4). (x + 2)^2 + (y - 1)^2 = 25.
Step-by-step explanation:
x^2 + y^2 + 4x - 2y - 20 = 0
x^2 + 4x + y^2 - 2y = 20
Completing the square on the x and y terms:
(x + 2)^2 - 4 + (y - 1)^2 - 1 = 20
(x + 2)^2 + (y - 1)^2 = 20 + 4 + 1
(x + 2)^2 + (y - 1)^2 = 25.
