Is 12 a solution to the equation × - 8 = 20? Explain how you know.
jeyben [28]

We have the following:

x-8=20

solving for x

\begin{gathered} x=20+8 \\ x=28 \end{gathered}

The solution of x is equal to 28, therefore 12 is not a solution of the equation

PLEASE ANSWER
Olenka [21]

Answer:

x(1 - .4)

Step-by-step explanation:

x = regular price.

1 - .4 = .6 = 60%

The sale price is equal to the full price (aka x) minus the discounted price (40% of x = 40/100 times x =  .4x)

Therefore sale price = x - .4x or x(1 - .4)

The system of linear inequalities x + 10y ≤ 80, x ≥ 30 and y ≤ 4 is represented in a graph below

<h3>Graph of Linear Inequality</h3>

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.

To solve this problem, we would require the use of graph which can easily be done with a graphing calculator.

x + 10y ≤ 80

x ≥ 30

y ≤ 4

The graph of the inequalities is attached below

In 2015, an autonomous vehicle drove from the Golden Gate Bridge to New York City at an average speed of 15.7 miles per hour. Th
ivolga24 [154]

The speed is the distance covered by an object at a particular time. The distance that is covered by the vehicle is 3,391 miles.

<h3>What is speed?</h3>

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

Speed = Distance / Time

Given that the journey took 9 days. Therefore, the time in hours will be equal to,

Time = 24 hours/day × Number of days

        = 24× 9

        = 216 hours

Also, given that the speed of the vehicle is 15.7 miles per hour, the number of hours for which it travels is 216 hours.

Distance = Speed × Time

              = 15.7 miles/hour × 216 hours

              = 3,391.2 miles

Hence, the distance that is covered by the vehicle is 3,391 miles.
