Let y = the number of standard strings.

x + y = 80,

4.50x + 1.50y = 225

He ordered
premium strings.
He ordered
standard strings.

So we know that Tara ran 2670,  and Henry ran half of this ( 2670 ÷ 2 = 1335). We also know that the race is 5000, This makes the equation 5000 - 1335 = 3665. I hope this helps you in some way.

Evaluate the following expression when a = 5 and b = 1. Then, plot the resulting value on the provided number line.

Answers

Answer:

-1

Step-by-step explanation:

The solution to the expression using the values a = 5 and b = 1 is - 1

The equation given :

12 + [2 - (4 × a²)] ÷ 7 + b

The given values of a and b are ; 5 and 1 respectively

Substitute the values of a and b into the equation 12 + [2 - (4 × 5²)] ÷ 7 + 1

Using BODMAS :

solve the expression in the bracket first :

12 + [2 - 100] ÷ 7 + 112 + [-98] ÷ 7 + 1

Solve the division next :

12 - 14 + 1

Solve the addition next :

12 - 13-1

Therefore, the solution of the expression with the given values of a and b is - 1

Describe the work of art. Make detailed notes about what you see in the artwork. Notice what type of medium was used to make the piece. This is where you would look at the elements of art (Line, Color, Shape, Texture, Value, Space, and Form) and how they are used. 2. Analyze the work of art. This is where you look at how the piece is put together. This is where you look at how the artist used the principles of design (Balance, Proportion, Harmony, Contrast, Emphasis, Movement, Pattern, Rhythm, Variety, and Unity) in the piece of art. 3. Interpret the work of art. This is where you assign meaning to the artwork. Sometimes it is helpful to know more about the artists life when working on this portion of a critique. It may help you to understand what the artist intended you to feel. What do you think was the artists goal with this work? Whether you have that information or not, you still can get a sense of what the artwork is telling you. 4. Judge the artwork. At this point you decide if the work is successful or not. In order to do this you must decide if the artist achieved the goal that you think they had in creating the art. Some art is art for the sake of art, while other art is clearly telling a story or making a point Which expression is equivalent to 2x + 2x + 2y + 2y? Solve the inequality: -2z - 3 < 5
