If youre writing an exprssion all you need to do is make variables and multiply by the given number A, C, and S will be our variables.
2A + 3C + 1S = Total cost for andrews family
4A + 2C = Total cost for Spencers family
Now, Does 2A + 3C + 1S = 4A + 2C
lets say A = 5 , C = 3 , and S = 2
2(5) + 3(3) + 1(2) = 4(5) + 2(3)
10 + 9 + 2 = 20 + 6
21 = 26
if this is your example then No, the spencers family spent more than the andrews family, youll have to do the math differently and may come up with a different answer if you were given values that you didn't give us, but this is how its done :)
Hope this helps!
Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The perimeter of the rectangle will be : 
The perimeter will be : 
The perimeter will be : 
As per given question, the perimeter is given as 146 unit.
So,
Subtracting 6 on both sides
Plugging the value x in sides, the sides will be 
and
Hence the length of the longer side is 45 units. : Answer
Hope it will help :)
The equation would be
x - 18 = collection left
X = how much was your collection before you gave your brother 13 cards
Since we don't know how big was your collection before, this would be the equation to solve it.
Answer:
18%
Step-by-step explanation:
The computation of the percentage of the total fixed costs per unit is shown below:
= Total fixed cost ÷ Total cost
where,
Total fixed cost = Fixed manufacturing overhead + administrative salaries
= $12 + $24
= $36
And, the total cost is $200
So, the percentage of the total fixed costs per unit is
= $36 ÷ 200
= 0.18 or 18%
