Amount of flour Helena accidentally poured =5\frac{1}{6} =\frac{31}{6} cups of flour.

Amount of flour the cake requires =3\frac{1}{2} =\frac{7}{2} cups of flour.

Amount of flour that Helena should take out =\frac{31}{6} - \frac{7}{2}

                                                                          =\frac{31}{6} - \frac{7 \times 3}{2\times 3}

                                                                          =\frac{31}{6} - \frac{21}{6}

                                                                          =\frac{31-21}{6}

                                                                          =\frac{10}{6}

                                                                          =\frac{5}{3}

                                                                          =1\frac{2}{3} cups of flour.

Answer:The system of equations to describe the situation are

c + y = 8

6c + 3y = 36

Step-by-step explanation:

Let c represent the number of shirts.

Let y represent the number of caps.

Eight friends started a business. They will wear either a baseball cap or a shirt imprinted with their logo while working. This means that

c + y = 8 - - - - - - - - - - -1

They want to spend exactly $36 on the shirts and caps. Shirts cost $6 each and caps cost $3 each. This means that

6c + 3y = 36 - - - - - - - - - - 2

Sylvie folds a large piece of paper in half. The fold divides the paper into two equal parts. She folds it in half again. When s
Nikolay [14]
Each time you fold a paper it will double the amount of parts. When you think about it, it's just multiplying by 2 a bunch of times.

One fold is 2 times 1, which is 2.
The second fold is 2 times 2, which is 4.
The third fold is 4 times 2, which is 8.

Using this process, we can simplify that into exponents. If the amount of times you fold is x and the parts double for each fold, then the amount of parts can be represented by:

2^{x}

So if the amount of parts is given and we need the amount of folds, just keep doubling until you get to 64. The amount of times you doubled is the number of times Sylvie folded.

Later you will learn that the opposite of an exponent is a logarithm, which would look like this:

log_{2}(64) = ?

But don't worry about that yet.
