The simplest simplified form of the given expression is 3 9/10.
First, let us understand the mixed number;
A mixed number is made up of three components: a whole number, a numerator, and a denominator. The numerator and denominator are both components of the appropriate fraction that results in the mixed number.
Change all the given terms to improper fractions, we will get;
6 1/2 = (6 * 2 + 1) / 2 = 13 / 2
1 2/3 = (1 * 3 + 2) / 3 = 5 / 3
We are given;
13/2 ÷ 5/3
= 13/2 × 3/5
= 39/10
Change to mixed fraction, we will get;
39/10 = 3 9/10
Thus, the simplest simplified form of the given expression is 3 9/10.

Answer:
Step-by-step explanation:
3b(2x - z^3) = 2h - 7gx Distribute 3b
6bx - 3bz^3 = 2h - 7gx Add 3bz^3 to both sides
6bx = 3bz^3 + 2h - 7gx Add 7gx to both sides
6bx + 7gx = 3bz^3 + 2h Factor left side, factor out a gcf of x
x(6b + 7g) = 3bz^3 + 2h Divide both sides by (6b + 7g) to isolate x
x = (3bz^3 + 2h)/ (6b + 7g)

The complete question has been attached here.
What is the equation of the line that passes through the point (-4, 3) and slope of 3/4
The equation of the line that passes through the point (-4, 3) and slope of 3/4 is y = 3x/4+6.
According to the question,
We have the following information:
We have the point (-4,3) and a slope of 3/4.
We know that the following formula is used to find the equation passing through any point:
(y-y') = m(x-x') where m is the slope and in this case, y' = 3 and x' = -4
y-3 = 3/4{x-(-4)}
y-3 = 3/4 (x+4)
Multiplying 3/4 into the bracket:
y-3 = 3x/4 + 3
Moving -3 from the left hand side to the right hand side:
y = 3x/4+3+3
y = 3x/4+6
Hence, the equation of the line that passes through the point (-4, 3) and slope of 3/4 is y = 3x/4+6.

The value varies from 0 to one. Probability has just been introduced in mathematics to predict the likelihood of occurrences occurring.Probability (event) = favorable outcome / total outcome
Total primary color designers = 400.
The number of opinions for red = 92
The probability for designer prefer red = 92 /100
The probability for designer prefer red = 0.23
Then, the probability that a designer does not prefer red = 1 - 0.23

lee went shopping with $60.50 . he bought 5 boxes of blue berries and 3 watermelons and had $16.50 left each watermelon cost $8.30
Assuming the question is : "how much does 1 box of blueberries cost?"
After he bought 5 boxes of blueberries and 3 watermelons, he was left with $16.50
Therefore, 5 boxes of blueberries and 3 watermelons cost $60.50 - $16.50 = $44
We are given the cost of 1 watermelon is $8.30
Therefore, 3 watermelons cost $8.30 x 3 = $24.90.
-> 5 boxes of blueberries cost $44 - $24.90 = $19.10
-> 1 box of blueberries cost $19.10 : 5 = $3.82
Answer:
If your trying to find the total of the 5 boxes of blue berries the answer is
$19.10
Step-by-step explanation:
60.50 - 16.50 = 44$ meaning he spent that much.

To find the parallel line of y =3z+6 passing through the slope intercept points (-2,5).
For a line to be parallel to another line, by definition it must have the same slope.
Because the equation is in the slope-intercept form we can use the slope of the line.
The slope- intercept form of a linear equation is :
y=mx+b
Where m is the slope and b is the y− intercept value.
Therefore, for the given equation, the slope is 3.
Now we can use the point slope formula to determine the equation for the parallel line.
The point - slope formula states: (y−y1)=m(x−x1)
Where m is the slope and (x1,y1) is a point the line passes through.
Substituting the slope from the given line and the given point gives:
y−5=3(x+2)
Transforming this to the slope-intercept form by solving for y gives:
y−5=3x+6
y−5+5=3x+6+5
y=3x+11

Kelly is trying to decide which plan to use to download songs. She can download 8 songs for $9.60 or 15 songs for $15.00. Which plan offers the lowest cost per song?
Answer:
The second plan ($15.00 for 15 songs) offers the lowest cost per song.
Step-by-step explanation:
The objective is to find the plan that provides the lowest cost per song. "Lowest cost per song" is basically $/song. So let's compare the two plans by calculating the cost per song.
Plan 1: $9.60/(8 songs) = $1.20/song
Plan 2: $15.00/(15 songs) = $1.00/song
The second plan ($15.00 for 15 songs) offers the lowest cost per song.
A biker travels down the street at 15 m/s. It
takes 60 seconds to travel to the end of the
street. How long was the street?
The street was 900m long when the speed is 15m/s and, the time is 60 seconds.
What is meant by distance, speed, and time?To calculate speed, divide the distance traveled by the time it took to complete the voyage, so speed = distance divided by time. To determine the distance, multiply the speed by the passage of time. These equations can be reduced as s=d/t, where s represents speed, d represents distance, and t represents time.
Distance divided by time equals speed. Distance = time * speed
To solve for speed or rate, utilize the speed formula, s = d/t, which implies speed equals distance divided by time. To solve for time, utilize the time formula, t = d/s, which implies time equals distance divided by speed.
Given,
Speed of the biker who travels down the street=15m/s
Time taken=60seconds
Distance=?
We know that,
Distance=Speed× Time
Distance=15×60
Distance=900m
Therefore, the street was 900m long

A botanist created a linear model to predict plant height from soil acidity (pH level) for a certain type of plant. The slope of the model was 2.5 centimeters per pH level, the standard deviation of the sample of plant heights was 4 centimeters, and the standard deviation of the soil acidities was 1 pH level. What is the value of the correlation coefficient?
The value of the correlation coefficient is 0.625.
What is a correlation coefficient?Correlation coefficients quantify the strength of a relationship between two variables. A correlation coefficient is a number ranging from -1 to 1 that indicates the degree and direction of a relationship between variables. It is a statistical notion that aids in the establishment of a relationship between predicted and actual values collected in a statistical experiment.
In this case, the slope of the model was 2.5 centimeters per pH level, and the standard deviation of the sample of plant heights was 4 centimeters.
The correlation coefficient will be:

Maria's rectangular rug is twice as long as it is wide. The are of the rug is 76.88 square feet.
What is the perimeter of the rug?
The perimeter of the rug is 37.2
The first line says that the rug is twice as long as its width. If the width is taken as w and length is taken as l, we get an equation l= 2w. Since it is a rectangle, the area of the rectangle will be (length*width) which is equal to l*w.
Since l=2w, area = 2w*w = 2w^2. This is given equally to 76.88.
2w^2 = 76.88
w^2 = 38.44
w = 6.2
l = 2w = 2*6.2 = 12.4
Now, perimeter of rectangle is 2w+2l = 2*6.2 + 2*12.4 = 37.2
Hence the perimeter of the rug is 37.2
