Answer:

a. Short-Sleeve = 35

b. Long-Sleeve = 27

Step-by-step explanation:

Given data:

Total shirts sold = 62

short sleeved cost = 11 each

Long sleeved cost = 17 each

Total receipts = 844

<em>Let the count of short sleeved be X  and Let the count of long sleeved be Y</em>

X + Y = 62 <em>(equation 1) from the total shirts sold</em>

11X + 17Y = 844 <em>(equation 2) from the total receipts</em>

<em>From equation 1</em>    X = 62 - Y <em>(Equation 3)</em>

<em>Substituting equation 3 into equation 2</em>

11(62 - Y) +17Y = 844

682 -11Y + 17Y = 844

-11Y + 17Y = 844-682

6Y = 162

Therefore Y = 27

<em>Substituting Y into equation 3</em>

X = 62 - Y

X = 62 - 27

X = 35

Answer: 35 short sleeve shirts and 27 long sleeve shirts were sold.

Step-by-step explanation:

Let x represent the number of Short-Sleeve shirts that were sold.

Let y represent the number of long-Sleeve shirts that were sold.

A department store sold 62 shirts one day. This means that

x + y = 62

All short-sleeved shirts cost $11.00 each and all long-sleeved shirts cost $17.00 each. Total receipts for the day were $844.00. This means that

11x + 17y = 844 - - - - - - - - - - - - -1

Substituting x = 62 - y into equation 1, it becomes

11(62 - y) + 17y = 844

682 - 11y + 17y = 844

- 11y + 17y = 844 - 682

6y = 162

y = 162/6

y = 27

x = 62 - y = 62 - 27

x = 35

PLEASE HELP!!!!!!!!!!!!1

A. Let x = cheese and
y = chocolate
2x + y = 25
x + y = 20

B. Subtract the second equation from the first.
2x + y = 25
-(x + y = 20)
-—————
x = 5

Plug 5 back in to the second equation and solve for y.
x + y = 20
5 + y = 20
Subtract 5 from both sides.
y = 15
5 cheese and 15 chocolate

Used elimination method because coefficients on the y values were both 1 so it was easy to subtract the equations and eliminate the y variable.

(10-P) Help please, thanks.
Anuta_ua [19.1K]
The formula of linear equation is:
y1  -  y2 = m(x1  -  x2)
Where
x1 and x2: x coordinates(-1 and 3)
y1 and y2: y coordinates(-2 and 10)
m is the slope

We can then choose a point from the line to find the eqaution.

We need to first find the slope:
\frac{y1 - y2}{x1 - x2}
In this case:
\frac{ - 2 - 10}{ - 1 - 3}   \\ =  \frac{ - 12}{ - 4}  \\  = 3

In this case, as the y2 is given as 1,put (-1,-2) , and the slope(3 )into the eqaution :

y-(-2) = 3(x-(-1))
y+2 = 3(x+1)

Therefore
y + 2 = 3x + 1
is the answer.

Hope it helps!
