An item is regularly priced at $85. It is on sale for 40% off the regular price. How much in dollars) is discounted from the regular price?

Answer:

m = 4.58  

Step-by-step explanation:

Given equation :

2.4 ( m - 3) = 3.8

So now we open the brackets and multiply the terms.

⇒ 2.4 m - 7.2 = 3.8

⇒ 2.4 m = 3.8 + 7.2

⇒ 2.4 m = 11

⇒ m = [tex]\frac{11}{2.4}[/tex]

⇒ m = 4.58

Therefore, the correct value of the variable m by solving the equation is 4.58

Answer:

A = true

B = false

C = false

D = True

Step-by-step explanation:

Cartons of blackberries = 25

Jars of blackberry jam made = 9

Cartons of blackberries left = 10

Cartons of blackberry used = Cartons of blackberries - Cartons of blackberries left

= 25 - 10

= 15

Cartons of blackberry used = 15

Cartons of blackberry used per jam = Cartons of blackberry used / Jars of blackberry jam made

= 15/9

= 5/3

A = true

15 jars of blackberry = Cartons of blackberry used per jam × jars of black berry made

= 5/3 × 15

= 75/3

= 25 cartons of blackberry

B = false

She can make 15 jars of blackberry jam using 25 cartons of blackberry

C = false

Cartons of blackberries left = 10

Number of blackberry jam made with 10 cartons of blackberry = Cartons of blackberries left / Cartons of blackberry used per jam

= 10 ÷ 5/3

= 10 × 3/5

= 30/5

= 6

D = True

Answer:

[tex]\huge\boxed{Answer\hookleftarrow}[/tex]

Given,

[tex]3x - 2y = 5[/tex]

[tex]xy = - 2[/tex]

Now,

[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ [/tex]

Use the algebraic identity ⇻ (a - b)² = a² - 2ab + b²

[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ 3x {}^{2} - 2 \times 3x \times 2y + 2y {}^{2} = 5 {}^{2} \\ 9 {x}^{2} - 12xy + 4y {}^{2} = 25 \\9x {}^{2} + 4y {}^{2} = 25 + 12xy \\ 9x {}^{2} + 4 {y}^{2} - 1 = 24 + 12xy[/tex]

✐ So, the value of 9x² + 4y² - 1 is 24 + 12xy

Now,

xy = - 2

So, 12xy = 12 × - 2 = - 24

•°• 24 + 12xy

= 24 + (-24)

= 24 - 24

= 0

Answer:

3000 ft^2

Step-by-step explanation:

The top of the play ground

24 cm * 5ft/ 2cm = 60 ft

The side of the play ground

20 cm * 5ft /2cm = 50 ft

The area is

A = l * w = 60 ft * 50 ft = 3000 ft^2

Answer:

24.2

Step-by-step explanation:

The perimeter is the sum of the sides:

10.5 + 7.4 + 6.3 = 24.2

Problem 3

-------------------------

Explanation:

Two points from the graph are (10,2) and (20,4)

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (4-2)/(20-10)

m = 2/10

m = 1/5

The slope of the graph is 1/5.

Do the same for two points from the table. I'll use the first two rows

m = (y2-y1)/(x2-x1)

m = (4-2)/(10-5)

m = 2/5

The slope of the table is 2/5.

Subtract the two slopes to wrap things up:

2/5 - 1/5 = (2-1)/5 = 1/5

=====================================================

Problem 5

------------------------

Explanation:

Angles 1 and 3 are same side exterior angles, so they are supplementary due to the parallel lines set up here.

(angle1)+(angle3) = 180

(157) + (angle3) = 180

angle3 = 180-157

angle3 = 23 degrees

Answer:

To find the answer you must see if the numbers in the data set is within the range or lines of the box plot.

Step-by-step explanation:

Answer:

6 x 4 = 24, 24 x 2 = 48

7 x 6 = 42

7 x 4 = 28, 28 x 2 = 56

6 x 4 x 1/2(basically just dividing by 2) = 12, 12 x 2(two triangles) = 24

5 x 5 = 25, 25 x 2 = 50

Add given areas:

48 + 42 + 56 + 24 + 50 = 220 ft^2 is your answer.

Answer:

x = 3y - 2

Step-by-step explanation:

Given the equation y = 1/3(x+2), we are to make x the subject of the formula;

y = 1/3(x+2)

Cross multiply

3y = x+2

Subtract 2 from both sides

3y - 2 = x+ 2 -2

3y - 2 = x

Swap

x = 3y - 2

This give the required equation

Answer:

x=-2, -4

Step-by-step explanation:

1(x+3)^2-1=0

Add 1 to each side

1(x+3)^2-1+1=0+1

(x+3)^2=1

Take the square root of each side

sqrt((x+3)^2)=sqrt(1)

x+3 = ±1

x+3 = 1    x+3 = -1

Subtract 3 from each side

x+3-3 = 1-3    x+3-3 = -1-3

x = -2     x=-4

Answer:

X = -2 X = -4

Step-by-step explanation:

Answer:

A linear function is written in slope-intercept form as:

y = a*x + b

Where a is the slope and b is the y-intercept.

So any function of this shape, is a linear function, such that when graphed it is a straight line.

In this case, the function you wrote is:

Q: y = 1/3x + 2

Now, if the function is exactly what you wrote, then x is in the denominator:

y = 1/(3*x) + 2

Clearly, this is different than the general linear equation you can see above (here the variable is in the denominator) then in this case Q is non-linear.

If instead, the actual function Q is:

Q: y = (1/3)*x + 2

Then this is a linear equation, where the slope is 1/3 and the y-intercept is 2.

Answer:

y = 2x+4

Perpendicular lines, when you multiply their gradient, you will get -1. You can also find the negative reciprocal, which is 2. The point (0,4) is the y intercept, which is for. Hence, the equation is y=2x+4

Answer:

Rotary motion.

Step-by-step explanation:

Motion describes the movement of objects with respect to time.

When an object performs a circular or rotary motion, every point on the object moves around a central point in a continuous manner. Examples of objects that performs circular motion are: blades of an electric fan, rotation of the earth about its axis, the wheel of a moving bicycle etc.

From the cited examples, it would be observed that all points on the objects moves around a fixed central point.
