Answer:

5 hours and 40 minutes would be class

Step-by-step explanation:

We know that the total time is 7 hours, which in minutes would be:

7 * 60 = 420

420 minutes would be class, now, we subtract the other times that are not to be in class and it would be:

420 - 30 - 50 = 340

So we could say that in class it takes 340 minutes, and if we spend hours it would be:

340/60 = 5.67 hours or also 5 hours and 40 minutes would be class.

110 + 3x +11 = 16x + 4 solve for x
sashaice [31]

Answer:

x = 9

Step-by-step explanation:

110 + 3x + 11 = 16x + 4

121 + 3x = 16x + 4

<u>        -3x    -3x</u>

121 = 13x + 4

<u>-4             - 4</u>

117 = 13x

117 ÷ 13 = x

9 = x

Check:

110 + 3(9) + 11 = 16(9) + 4

121 + 27 = 144 + 4

148 = 148

Hurry I am being timed!!!
igomit [66]

Answer:

<h2>First graph.</h2>

Step-by-step explanation:

The given function is

y=\sqrt[3]{x-3}

Observe that the three units are a translation in horizontal direction. Specifically, indicates a 3 units translation rightwards, because negative units added to x means rightward movement. So, we need to a curve moved 3 units to the right.

Notice that the first graph is the only one moved three units rightwards. We deduct this because the function showed by the first graph is the only which crosses x=3.

Therefore, the right answer is the first graph.
