The value of x in the linear equation 4(x + 5) = 9x + 4x − 34 is 6 after applying the property.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have linear equation in one variable:

4(x + 5) = 9x + 4x − 34

4x + 20 = 9x + 4x − 34   (Distributive Property)

4x + 20 -4x + 34= 9x + 4x − 34 -4x +34    

(Subtraction Property of Equality and Addition Property of Equality)

54 = 9x

x = 6   (Division Property of Equality)

Thus, the value of x in the linear equation 4(x + 5) = 9x + 4x − 34 is 6 after applying the property.

The margin of error is ±2%

<h3>What is Margin error?</h3>

A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample.

Let x be margin of error and y be the percentages of the population.  

So,

y-x =33%

y +x = 37%

Solving above equations

2y= 70

y= 35%

and x= 2%

Hence, the margin of error is ±2%.

Deffense [45]

Answer:

1.4 hour, or 1 hr 24 min

Step-by-step explanation:

The trains separate at the rate (80 + 90) mph.

Recall that distance = rate times time, or time = distance / rate.

                                            238 mi

Here, the elapsed time is  -------------- = 1.4 hr, or 1 hr 24 min

                                             170 mph
