Solve, using the correct order of<br> operations, when x = 7 and y = 3<br> (x – 3) + 2y
sweet [91]

Answer:

10

Step-by-step explanation:

<em>Since it given that:</em>

<em>x = 7 and y = 3</em>

<em>We can substitute x and y:</em>

<em>(7-3) + 2(3)</em>

<em>7 - 3 = 4</em>

<em>4 + 2(3)</em>

<em>2(3) = 6</em>

<em>4 + 6 =10</em>

<em>Thus the answer is 10.</em>

After working problems on the board for 55 minutes  or 11 / 12 hour.

He gave the students the rest of the class period to work on homework.

Then the number of hours that students have to work on homework will be

⇒ 1 + 1/4 - 11/12

⇒ 5 / 4 - 11/ 12

⇒ (15 - 11) / 12

⇒ 4/12

⇒ 1/3 hours
