Alenkinab [10]3 years ago
5 0

\text {Hello! Let's Solve this Equation!}

\text {\underline {The First Step is to Subtract 3p}}

\text {24p-66-3p=3p+43-3p}

\text {Your New Problem Is: 21p-66=43}

\text {\underline {The Next Step Is to Add 66}}

\text {21p-66+66=43+66}

\text {Your New Problem Is: 21p=109}

\text {\underline {The Final Step is to Divide 21}}

\text {21p/21=109/21}

\text {Your Answer Would Be:}

\fbox {p=109/21}

\text {Best of Luck!}

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.

andrew11 [14]

Answer:

<u>There are 380 ways that 1st and 2nd place can be determined in the race</u>

Step-by-step explanation:

There are 20 possibilities for determine the 1st place

There are 19 possibilities for determine the 2nd place

Number of ways that 1st and 2nd place can be determined = 20 * 19

Number of ways that 1st and 2nd place can be determined = 380

In basketball, baskets are worth either 2 or 3 points. A missed shot, of course, is worth 0 points. During the 2007-2208 season,
rosijanka [135]

Answer:

1.15

Step-by-step explanation:

Multiply each shot by its point value. Then add. Divide this sum by the total number of shots taken.

288*2 + 79*3 + 340*0 = 813

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

288 + 79 + 340 = 707

813 / 707 = 14.992

The weighted average is approximately 1.15 points per shot.
