Each deli sandwich made uses 1/4 pound of roast beef. Marisa started with 5 pounds of roast beef and now has 3/4 pounds left.
Iteru [2.4K]
Let us assume the number of sandwiches made by Deli = x
Amount of roast beef required for making 1 sandwich = (1/4) pound
Total amount of beef that Marisa started with = 5 pounds
Amount of beef that was left = (3/4) pounds
Then
[(1/4) * x] + (3/4) = 5
(x/4) + (3/4) = 5
(x + 3)/4 = 5
x + 3 = 5 * 4
x + 3 = 20
x = 20 - 3
   = 17
So we can see from the above deduction that 17 Deli sandwiches was made by Marisa. I hope the procedure is clear enough for you to understand.

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

How do I find csc (13pi/6) using the unit circle or calculator? Either way is fine.
Alex777 [14]
We are asked in the problem to find csc (13pi/6). first we can convert the radians angle first to degrees that is equal to 390 degrees. The terminal angle is 30 degrees. csc is the reverse of sin. sin 30 is equal to 1/2, positive since in the first quadrant.  hence the answer is 2.
