The variables x and y have their values to be 50 degrees and 20 degrees, respectively

<h3>How to determine the values of the variables?</h3>

The triangle, the lines and the angles represent the given parameters

On the triangle, we have the following corresponding angles

Angle 5y and angle 2x

Corresponding angles have equal measure

So, we have the following representation

2x = 5y

Divide both sides by 2

x = 2.5y

The angle on a straight line is 180 degrees

So, we have the following representation

5y + 180 - 2x - (x - y) + 30 = 180

Remove the bracket

So, we have

5y + 180 - 2x - x + y + 30 = 180

Subtract 180 from both sides

This gives

5y - 2x - x + y + 30 = 0

Substitute x = 2.5y in 5y - 2x - x + y + 30 = 0

5y - 2(2.5y) - 2.5y + y + 30 = 0

So, we have

5y - 5y - 2.5y + y + 30 = 0

Evaluate the like terms

1.5y = 30

Divide both sides by 1.5

y = 20

Recall that x = 2.5y

So, we have

x = 2.5 * 20

Evaluate

x =50

Hence, the measures of the variables are x = 50 and y = 20

Marcus is skiing. He is 869 1/10 get up the mountain. He descends to 450 7/10 feet. What is his change in elevation

MatroZZZ [7]

Answer:

418 4/10

Step-by-step explanation:

To answer this we subtract 450 7/10 from 869 1/10.

We must borrow a '1' from 869 1/10: 868 11/10

Now subtract 450 7/10 from 868 11/10:

418 4/10 (CHANGE IN ELEVATION)

This reduces to 418 2/5.

djverab [1.8K]

Answer:

There are 1.25 days in 30 hours or 1 1/4 days in 30 hours

Step-by-step explanation:

As we know one day is 24 hours. So if we divide 30 hours by 24 hours (or one whole day) then we get 1.25 days or also known as 1 1/4 days

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
