on average the number of electric guitars sold in texas each year is $91,399, which is seven times the average number of guitars sold each year in Wyoming. How manu electric guitars, on average, are sold each year in Wyoming?

What is Multiplication?

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

Given that,

on average the number of electric guitars sold in Texas each year is $91,399, which is seven times the average number of guitars sold each year in Wyoming.

Average number of guitars sold each year in Texas = 91,399

This number is seven times the average number of guitars sold each year in Wyoming.

Let x be the average number of guitars sold in Wyoming each year.

7x = 91,399

Dividing both sides of the equation by 7,

x = 91399 / 7

x = 13,057

Hence 13,057 electric guitars are sold each year in Wyoming.

Your friend grace needs help to find the values of x,y and z in the figure below

Answers

Answers:

x = 57

y = 86

z = 37

=================================================

Work Shown:

x+123 = 180 .... since x and 123 form a straight line

x = 180-123

x = 57

y = 86 since the y and 86 angles are vertical angles

-------

For any triangle, the three angles always add to 180. So,

x+y+z = 180

57+86+z = 180

143+z = 180

z = 180-143

z = 37

As a check,

x+y+z = 57+86+37 = 180

which confirms the value of z

Is the opposite of an opposite number always going to be positive?

Answers

No, the opposite of an opposite will not always be positive. the opposite of -4 is 4, and the opposite of that is -4, so the opposite of the opposite of the number -4 is -4, which is not positive. On the other hand, it CAN be positive. The opposite of 7 is -7, and opposite of that is 7, which is positive.
yes it is because if you reflect for a min, the opposite (which is a negative) of the opposite is always going to be a positive.
