Martha can write 3.75 essays in 15 hours. (Which is a lot for me)

Step-by-step explanation:

First, I divide 2 by 8.

2 ÷ 8 = 0.25

Next I multiply 0.25 by 15.

0.25 * 15 = 3.75

So, the answer is 3.75

Hope this helps! :)

Answer:

Step-by-step explanation:

Median= Middle which is 14

Answer:

Slope: 5/2

y-intercept: (0,-3)

The graph of the equation y=5/2x-3 is plotted.

Given data:

The linear equation is represented as y = ( 5/2 )x - 3

To graph the equation y = (5/2)x - 3, use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

So, the slope is 5/2, and the y-intercept is -3.

To plot the graph, follow these steps:

Plot the y-intercept:

Start by plotting the point (0, -3), which represents the y-intercept.

Use the slope to find another point: Since the slope is 5/2, use the rise and run method. From the y-intercept point (0, -3), move up 5 units (positive 5) and then move to the right 2 units. This gives another point on the line, which is (2, 2).

Hence, the equation is y = ( 5/2 )x - 3 and the graph is plotted below.

Answer:

13 - 6j/5

Step-by-step explanation:

After simplification of the given equation, the value obtained is equal to (13 - 6j)/5.

A phrase must be simplified and made shorter using a variety of methods. The steps required to decrease something are carried out according to a specified order known as BODMAS.

Make a fraction simpler by reducing it to the base form. If both the numerator and denominator of a fraction only include the integer, the fraction is considered to be in its basic form.

As per the data given in the question,

12 + (-4) -2/5j - 4/5j + 5

12 - 4 + 5 - 2/5j - 4/5j

13 - (2 - 4)j/5

= (13 - 6j)/5

Answer:

5x-3x = 2x

Step-by-step explanation:

"The difference" = the substraction of two numbers

(something) - (something)

"The difference between the product of five and a number"

By product means multiplication. So, the multiplication of five and a number. Before, you have been told to represent the number with "x", and thats what you will do now.

(5*x) =  (5x)

(5x) - (something)

"The difference between the product of five and a number and three times the number"

With three times the number, we mean the same letter "x" & three times will be the amount of times we will multiply it. So, by the end we will have:

(5x)-(3x)

Now we just rest them

5x-3x= 2x

Hope it was helpful ;)

The difference between the product of five and a number and three times the number will be two times the number and algebraic expression will be 5x - 3x = 2x.

An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.

In other meaning, expression is very useful to determine the end or root value of constraint.

For example 3x +5y

The constraint of expression is represented as = or <, >.

Given that,

x is that number,

Five times the number = 5x

Three times the number = 3x

Now,

Difference ⇒ 5x - 3x = 2x

Hence "The algebraic expression is  5x - 3x = 2x and The difference between the product of five and a number and three times the number will be two times the number".

Answer:

A bus drives for 3 1/2 hours at an average speed of 56mph.

To Find :

How far does the bus drive?

Step-by-step explanation:

Times of journey(T)=3 1/2 =7/2hours

Average speed of bus(v)=56mph

We know the formula:

Average speed (v)=total distance (d)/Time(T)

So:

Total distance (d)=qverage speed(v)×time(t)

Total distance (d)=56×7/2

Total distance(d)=28×7=196 miles

It means distance travel by bus is 196 miles.

Answer:

shape as that of the base of the solid

Step-by-step explanation:

A solid has a three dimensional shape. A three dimensional shape has both length, breadth and height. If the solid is being cut parallel to the base, a two dimensional shape (has length and width) is formed.

The shape of the two dimensional shape is the same as the shape of the base. Hence if solid is cut parallel to the bases, the shape formed would have the same shape as that of the solid base.

Answer:

the simplified version of 3/9 would be 1/3 but other equivalent fractions of 3/9 would include but are not exclusive to: 2/6, 4/12, 5/15, and etc.

The required fraction 3/9 is equivalent to 1/3.

Given that the fraction is 3/9.

Equivalent fractions are the fractions are same at their simplest form.

Let a/b be the fraction, then the equivalent fractions are

2a/2b, 3a/3b, 4a/4b, 5a/5b,   etc

To find an equivalent fraction, we simplify the given fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).

In this case, the GCD of 3 and 9 is 3.

Dividing both 3 and 9 by 3, we get:

3 ÷ 3 = 1

9 ÷ 3 = 3

Therefore, the fraction 3/9 simplifies to 1/3, which is an equivalent fraction.

Answer:

y = (5/3)x +3

Step-by-step explanation:

slope intercept form

Y = mx +b form

so we need to solve the given equation for y

1.  5x-3y =-9

2 . 5x -3y +3y = -9 +3y (adding both sides 3y)

3. 5x = -9 +3y

4. 5x +9 = -9 +9 + 3y (adding 9 to bot sides)

5. 5x +9 = 3y

6. (5/3)x + 9/3 = (3y)/3 ( divide both sides by 3 to get y  alone)

so, the final answer will be

y = (5/3)x +3

Answer: B. Acute and F. Equilateral

Step-by-step explanation: Acute triangles contain interior angles that are less than 90 degrees. All triangles must have interior angles that add to 180 degrees when combined. In this triangle, all interior angles are equal. Therefore, we can divide 180 by the 3 angles to find that each angle is 45 degrees. 45 degrees is less than 90, so it is an Acute Triangle.

In equilateral triangles, all sides have the same length. We can see in the diagram that all of the sides contain the same marking, indicating they are the same length. So, the triangle is also equilateral.
