Answer:

x = -9

Step-by-step explanation:

-5 = \frac{x}{3} - 2

add 2 to both sides:

\frac{x}{3} = -3

multiply both sides by 3:

x = -9

Answer:

Width = 59

Step-by-step explanation:

Given

The above data

Required

The class width

To do this, we simply calculate the difference between the class limits of any one of the classes.

Taking 1187–1246 as a point of reference, the class width is:

Width = 1246 - 1187

Width = 59

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
