Answer: a package of cookies cost $ 5 and each bag of chips cost $5
Step-by-step explanation:
Let x represent the cost of a package of cookies and y represent the cost of a bap of chips ,then from the first statement :
4x + 4y = 40
dividing through by 4 , we have
x + y = 10 ........................... equation 1
From the second statement
3x + 5y = 40 ..................... equation 2
Solving the system of linear equation by substitution method , from equation 1 , make x the subject of the formula , that is
x = 10 - y ................... equation 3
substitute x = 10 - y into equation 2 , we have :
3 (10 - y ) + 5y = 40
30 - 3y + 5y = 40
30 + 2y = 40
subtract 30 from both sides
2y = 40 -30
2y = 10
y = 5
substitute y = 5 into equation 3 , equation 3 becomes
x = 10 - 5
x = 5
Therefore ; a package of cookies cost $ 5 and each bag of chips cost $5
The garden is 24 ft by 14 ft
The walkway stretches all the way around the garden
The walkway is 4 ft wide
Perimeter is found by adding the length of the four sides so this would be 24 + 14 + 24 + 14 = 76
24 + 24 = 48
14 + 14 = 28
48 + 28 = 76
I don't know for sure but I think the length would be 34 using the length formula
p / 2 - w
so 76 / 2 - 4
38 - 4
34
I have no clue though. A picture would make it easier

Answer:
x = 8/5
Step-by-step explanation:
first multiply both side by -1, it makes both side positive
1x/2 = 4/5
now multiply both sides by 2 to get the x by itself
x = 8/5
if they want improper fraction x = 1
Answer:
3/6 or 1/2
Step-by-step explanation:
⇒ out of 6 blocks 3 are shaded so, it will be 3/6
⇒ out of 6 blocks 3 are shaded (3 is half of 6) so, it will be 1/2
