Some members of the cooking club are making cakes which they will sell at a street fair for $10 apiece. It costs $10 for a booth
Alika [10]

Answer:

The cooking club sales covers the expenditure when 2 piece of cakes are sold.

Step-by-step explanation:

Given:

Selling price of each piece of cake = $10

Cost for booth at fair = $10

Ingredients for each piece of cake = $5

We need to find the number of pieces of cake sold when the sales cover the expenditures.

Solution:

Let the number of pieces be 'x'

So We can say that the point at which the sales cover the expenditures can be calculated as Selling price of each piece of cake multiplied by number of pieces will be equal to Cost for booth at fair plus Ingredients for each piece of cake multiplied number of piece of cakes.

framing in equation form we get;

10x =10+5x

Now Subtracting both side by '5x' using Subtraction property we get;

10-5x=10+5x-5x\\\\5x=10

Now Dividing both side by 5 we get;

\frac{5x}{5}=\frac{10}{5}\\\\x=2

Hence The cooking club sales covers the expenditure when 2 piece of cakes are sold.

Use the commutative law of addition to write a equivalent expression ab+c
Scilla [17]

Answer:

c + ab

Step-by-step explanation:

The way an expression is written is the given you have presented to us.

The commutative law of addition would turn it around as

c + ab.

It just means change the order when adding. Not all systems allow this. It matters which way you put it in some systems.

Select Proportional or Not Proportional to correctly classify each pair of ratios. Proportional Not Proportional 12/30 and 18/45
Zinaida [17]
12/30 = 18/45....cross multiply
(30)(18) = (12)(45)
540 = 540...proportional

another way to tell is to see if they are equivalent...because proportions are nothing but equivalent fractions.
12/30 = 2/5
18/45 = 2/5
so yes, they are proportional
