The area of a trapezoid is 15 cm2. The height is 3 cm, and the bases have lengths of 2x and 3x cm. Find x, and give the lengths of the two bases.

Answers

Answer 1

Answer:

x = 2, bases are 4 cm and 6 cm

Step-by-step explanation:

Area formula:

A = 1/2(b1 + b2)h

Substitute the given values:

15 = 1/2(2x + 3x)(3)1/2(15x) = 15x = 2

The bases are:

b1 = 2*2 = 4 cmb2 = 3*2 = 6 cm

Answers

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

Step-by-step explanation:

y + 3x = -1
y = 1/2x+ 20

Answers

im not sure if it’s right but I think it’s -6,17
So you can substitute equation 2 in equation 1.

U believe your equation 2 should read y= x/2 + 20 (the x is next to the 1 and not to the 2, right)

So after substituting, we have:

(x/2)+20+3x = -1

Multiply the whole equation by 2:

x + 40 + 6x = -2
7x = -2-40
7x = -42
x = -6

Replace x=-6 in equation 1:

y + 3(-6) = -1
y - 18 = -1
y =17

Which table represents a linear function?

Answers

I believe it would be the 4th one! :)

graph the equation y=5/2x-3

Answers

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.

What is Simplification?

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

Answers

Answer:

196 km

Step-by-step explanation:

Distance = speed x time

So to work it out, it would be 3.5 x 56

= 196km

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.

Imagine making slices through the solid parallel to the bases. What two-dimensional shapes are formed

Answers

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.

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

What is the algebraic expression?

Answers

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.

What is an expression?

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".
