Naysha listens to the radio for five-sixths of an hour each day. which expressions represent the time naysha spends listening to
Yakvenalex [24]

The time Natasha listens to the radio can be represented as 7 times five sixths, 35/6 or 5/6 + 5/6 + 5/6 + 5/6 + 5/6.

<h3>How to find out the time Natasha listens to the radio in one week?</h3>
  • Time per day: 5/6 of an hour
  • Time per week: 5/6 + 5/6 + 5/6 + 5/6 + 5/6 = 35/6

or 5/6 x 7 = 35/6

<h3>How to represent this?</h3>

There are three options:

  • 5/6 + 5/6 + 5/6 + 5/6 + 5/6
  • 35/6
  • 5/6 x 7

Solve for x - PLEASE NEED HELP, this is my 3rd time posting it.
mafiozo [28]

Answer:

x=58

Step-by-step explanation:

First, remember that the maximum degree of an angle totals 360°.

Since we already have 294°, this means that what is left must total 360\textdegree - 294\textdegree= 66\textdegree.

Therefore, this means that our two smaller angles must equal 66°. So:

(36)+(x-28)=66

Solve for x. Add on the left:

x+8=66

Subtract 8 from both sides. Therefore, the value of x is:

x=58
