<h3>Given Equation:</h3>
x = 7 + 3y
or, x - 3y - 7 = 0 ........ (i)
5x + 6y = 14
or, 5x + 6y - 14 = 0 .........(ii)
<h3>To Find:</h3>
The value of x and y.
<h3>Solution:</h3>
By dividing eq. ii by 2, we get
5/2x + 3y - 7 = 0 ........ (iii)
By adding eq. i and eq. iii, we get
15/2x = 0
or, <u>x = 0</u> ........(iv)
By putting eq.(iv) in eq. (i), we get
0 - 3y - 7 = 0
or, -3y = 7
or, <u>y = </u><u>-</u><u>7/</u><u>3</u>
<h2>Answer: ( 0, -7/3 )</h2>
The value of x and y is 0 and -7/3 respectively.
A.) 3/4 are plain
b.) 75% are plain
c.) 18 are plain and 6 are sesame. 2 dozen bagels is the same as 24 bagels. Since there are 4 total parts, you have to divide the number of bagels into 4 equal parts [24 / 4]. Since each part is 6 bagels, multiply 6 by 3 since the ratio of plain to sesame is 3:1. Yours should get 18 plain bagels. Then, since 3 of the 4 parts are plain, and each part is 6 bagels, there are 6 sesame bagels.
-5 is the answer I believe
The manager’s likely error was forgetting to add the $2 back to the $18. Because $2 is roughly 11% of $18 for a markup you need to add the $2 back into the $18 for a total of $20.
