Answer:

-4y + 20

Step-by-step explanation:

4(-y+5)

What we need to do here is get rid of the parentheses, which can be achieved through multiplication.

This is another way of saying 4 times -y plus 4 times 5.

Let's break the the parentheses down into 2 separate formulas.

4(-y) and 4(5)

Now we can multiply these two together to get -4y and +20. When combined, we get -4y +20.

James bought 5 boxes of cookies and 2 cakes at the store for his party. The cakes cost $4 each and his total bill was $28.50, ho
maxonik [38]
Number of cookie boxes bought by James = 5
Number of cakes bought by James = 2
Cost of each cakes = $4
Total bill paid by James = $28.50
Let us assume the cost of the each boxes of cookies = x
Then
5x + (2 * 4) = 28.50
5x + 8 = 28.50
5x = 28.50 - 8
5x = 20.50
x = 20.50/5
   = 4.10
So we can see from the above deduction that the cost of each boxes of cookies bought by James is $4.10

A self-serve frozen yogurt restaurant charges its customers according to the weight of their filled frozen yogurt cup. So, the a
jeyben [28]
If the price of the yogurt is directly proportional to the weight of the purchase, then it can be expressed as:

Price of yogurt = weight of purchase

With the given above, it can be further expressed as:
$5.04 = 12 oz

These can be expressed in ratio form, which is:

5.04/12

Thus, if the cup weighs 8 oz and we don't know how much it costs, then the ratio should be:

n = 8 oz, or in fractions:
n/8

After this, simply equate the two and cross multiply. 
5.04 / 12 = n/8
5.04(8) = 12n
40.32 = 12n

Then solve for n:
40.32 /12 = 12n/12
n = 3.36. 

Thus, the 8 oz. cup of yogurt costs $3.36.
