Answer:

\frac{9}{5}

Step-by-step explanation:

\frac{4}{9} × \frac{45}{36}

= \frac{4}{9} × \frac{5}{4} ( cancel 4 on numerator/ denominator )

\frac{5}{9}

Given a number n then its reciprocal is \frac{1}{n}

Then the reciprocal of \frac{5}{9} is

\frac{1}{\frac{5}{9} } = \frac{9}{5}

A waitress sold 12 ribeye steak dinners and 39 grilled salmon totaling $575.53 on a particular day. Another day she sold 25 ribe
DedPeter [7]

Answer:

The cost of a ribeye steak dinner is $18.60.

The cost of a grilled salmon dinner is $9.03.

Step-by-step explanation:

let r be the cost of a ribeye steak dinner

let g be the cost of a grilled salmon dinner

Represent the two situations using equations:

12r + 39g = 575.53   (equation 1)

25r + 13g = 582.43   (equation 2)

The best method to use for this case is elimination, which is when you get rid of one of the variables by subtracting or adding.

Since the coefficients for "g" are 39 and 13, they can be eliminated if equation 2 was triple itself.

(25r + 13g = 582.43)  X 3

= 75r + 39g = 1747.29  (new equation 2)

Subtract "equation 1" from "new equation 2"

.   75r + 39g = 1747.29

<u>-   12r + 39g = 575.53</u>

.    63r + 0g = 1171.76    <=we only deal with "r" because 0g is nothing

.             63r = 1171.76    <=divide both sides by 63 to isolate r

.                 r = 18.60       <=rounded from 18.599...

The cost of a ribeye steak dinner is $18.60.

Use any one of the equations to solve for "g", the cost of grilled salmon dinners. I will use equation 1.

12r + 39g = 575.53

Substitute r = 18.6

12(18.6) + 39g = 575.53   <=only one variable now

223.2 + 39g = 575.53     <=subtract 223.2 from both sides

39g = 352.33             <=divide both sides by 39 to isolate g

g = 9.03  <=rounded from 9.0341...

The cost of a grilled salmon dinner is $9.03.

marin [14]

Answer:

4 feet of wall should be on each side of the painting.

Step-by-step explanation:

Given that a 4 foot wide painting should be centered on a 12 foot wide wall, to determine how many feet (X) should be on each side of the painting, the following equation must be solved:

(Total wide of the wall - wide of the painting) / 2 = X

(12 - 4) / 2 = X

8/2 = X

4 = X

Therefore, 4 feet of wall should be on each side of the painting.
