!!!HELP AS SOON AS POSSIBLE!!!<br><br> Simplify: -2/9 divided by 3 1/4
ohaa [14]
<h3>Answer: the fraction -8/117</h3>

----------------

First, convert to an improper fraction

3 & 1/4 = 3 + (1/4)

3 & 1/4 = (12/4) + (1/4)

3 & 1/4 = 13/4

The mixed number 3&1/4 turns into the improper fraction 13/4

---------------

-2/9 divided by (3&1/4) = -2/9 divided by 13/4

To divide two fractions, you flip the second one and then you multiply

"-2/9 divided by 13/4" turns into "-2/9 times 4/13" after this happens

Then you multiply straight across. The numerators stick together. The denominators stick together.

numerators: -2*4 = -8

denominators: 9*13 = 117

We end up with the fraction -8/117

This cannot be reduced as there are no common factors (other than 1) between 8 and 117.

egoroff_w [7]
<h2>(x, y) = (x, 2 + 5/6 x)</h2>

Step-by-step explanation:

-5x + 6y = 12

y = 5/6x + 2

<h2>_______________</h2>

-5x + 6y = 12

-5x + 6(5/6x + 2) = 12

Mr and Mrs Smith buy tickets for hemselves and their four children.
Nookie1986 [14]

Answer:

Cost of an adult ticket is £10.75

Step-by-step explanation:

Given:-

Cost of 1 adult ticket is £6 more that the cost of a child ticket.

Total cost of 6 tickets = £40.50

c is cost of a child ticket and a is the cost of an adult ticket.

To find:- Cost of 1 adult ticket =?

Solution:-

For 2 adults and 4 children, and the total cost of tickets is £40.5, we get the following equation,

2a+4c=40.5                 -----------------(1)

As the Cost of 1 adult ticket is £6 more than the cost of a child ticket, we can the following equation,

a=c+6                          -----------------(2)

Now, substituting the value of a from equation 2 in equation 1 we get,

2a+4c=40.5

2(c+6)+4c=40.5

2c+12+4c=40.5

6c=40.5-12

6c=28.5

c=\frac{28.5}{6}

c=4.75                        --------------------(3)

Now substituting the value of c from equation 3 in equation 2,

a=c+6

a=4.75+6

a=10.75

As a is the cost of 1 adult ticket,

Therefore Cost of an adult ticket is £10.75
