$16 was only for the layer.
$52-$16= cost of the cupcakes in total.
$36=cost of all cupcakes
36/24= cost of one cupcake
1.5= cost of one cupcake

each cupcake costs $1.50

Your equation is 24x + 16 = 52 where x is the cost of each individual cupcake.

First step is to take away the 16 from each side so that we only have the cupcakes to deal with the overall cost without the cake.

52 - 16 = 36.

Your new equation is 24x = 36

Divide both sides by 24 to isolate the variable x.

x = 36/24 = 1.5 or 1.50

The cost of each cupcake is $1.50.

Whats the answer to these? (These are called Proper fractions.)
Darya [45]

Answer to the first question: 7/10ths of a mile

Explaination: When adding fractions, you need to have a common denominator. Since dividing 3/10 by 2 to get a denominator of 5 makes 3 a decimal, it's easier to multiply 2/5 by 2 to get a denominator of 10. You do the same to the top that you do to the bottom: \frac{2*2}{5*2} = \frac{4}{10}. From there, just add 4/10 and 3/10 to get the answer: 7/10ths of a mile.

Answer to the second question: Daniel read three (3/10) more books

Explaination: Since you can't evenly multiply 5 or 2 to get the opposite number, it's easier to multiply to the lowest common multiple. The easiest way to find that is to multiply both denominators (5*2=10). You'll have to multiply the numerator by the same amount you multipled the denominator by. For Daniel, that would mean: \frac{4*2}{5*2} = \frac{8}{10}. For Edgar, that would mean: \frac{1*5}{2*5} = \frac{5}{10}. So, Daniel read 3 more books than Edgar.

Answer to the third question: 2/4 mile (or 1/2 a mile)

Explaination: 2/8 can be simplified, by dividing the top and bottom by 2, resulting in 1/4. Since both fractions have the same denominator (/4), you can add them to get 2/4ths. This can be simplified further to half (1/2) a mile.

prisoha [69]

Answer:

A company produces electric insulators. The strength of the insulators is important since a broken insulator may cause a short circuit. Unfortunately, the strength varies significantly due to the material. Because of the expense, only a limited number of insulators could be tested. The engineers sampled 25 insulators (From a production run of 200), and conducted a destructive test to determine the force that was required to break the insulators. The mean value of this force was 1723 lbf with a sample standard deviation of 90 lbf. You may approximate the population standard deviation with the sample standard deviation for the following questions. a. Determine if the population is large enough or if a finite population correction (FPC) factor is needed. If so, what is the FPC factor? b. For 95% confidence, determine the margin of error (+ lbf) c. For these conditions, estimate the range of the probable population mean. Provide lower and upper values. For 95% confidence, determine the margin of error ( Assume the same mean and sample standard deviation. What is one advantage and one disadvantage of using 50 insulators instead of 25 insulators? d. lbf) if 50 insulators were tested.

Can you help me<br>I don't really know this question very good so can you help me please
amid [387]

Answer:

1.92 miles

Step-by-step explanation:

she had walked 10 miles so that is where you start

Monday she had walked 2.38 so you subtract that from her total

Tuesday she had walked 2.4 so you subtract that from your new total

Wednesday she had walked 3.3 and you subtract that from the new total also

Thursday she had not walked anything so your remaining total is the amount she had walked on Friday

What is 4 x what = 97
ikadub [295]

If you mean, what is 4x = 97......

4x = 97                   -Divide both sides by 4

4x / 4 = 97 / 4

x = 24.25

Hope this helps you! Have a happy Thanksgiving, here's a turkey!
