Answer:

r = 3

Step-by-step explanation:

[tex]\dfrac{r}{2} - 3 = 3(4 - \dfrac{3r}{2} )[/tex]

The first step to solve for "r" is to simplify the distributive property on the RHS. To simplify the distributive property, we need to multiply the term outside the parenthesis with the terms inside the parenthesis.

[tex]\rightarrow \dfrac{r}{2} - 3 = 12 - \dfrac{9r}{2}[/tex]

Now, add 9r/2 and 3 both sides to isolate the constants and variables.

[tex]\rightarrow \dfrac{r}{2} + \dfrac{9r}{2} = 12 + 3[/tex]

Simplify both sides.

[tex]\rightarrow \dfrac{10r}{2}= 12 + 3[/tex]

[tex]\rightarrow 5r = 15[/tex]

Divide 5 both sides.

[tex]\rightarrow \boxed{r = \frac{15}{5} = 3}[/tex]

Equation of a circle

The equation of the circle that represents the general form of a circle with a center at (–2, –3) and a radius of 4 units.

[tex](x-h)^{2} +(y-k)^{2} =R^{2}[/tex]

Substituting the values,

[tex](x-(-2))^{2} + (y-(-3))^{2} =4^{2}[/tex]

[tex](x+2)^{2} + (y+3)^{2} =4^{2}\\[/tex]

[tex]x^{2} +4x+4+y^{2} +6y+9=0[/tex]

[tex]x^{2} +4x+y^{2} +6y-3=0[/tex]

Therefore, the option C is correct.

The equation represents the general form a circle with a center at

(–2, –3) and a diameter of 8 units is

[tex]x^{2} +4x+y^{2} +6y-3=0[/tex]

First, we need to understand the formula and simply comprehend it.
In this case, we're dealing with an area of a quadrilateral which is a four-sided shape.

The area is base times height.

You will simply need to do 1.8 x 5 = m

That is pretty simple. You need to setup a question like this:

what values of a are the following expressions true?

|a-5| =5-a

Try putting values of ( a )

picking random number :-

Putting a = 6 :-

[tex] |a-5| =5-a \\ |6-5| =5-6 \\ | 1| = -1 \\ 1 \cancel = ( - 1) [/tex]

so a is not equal to 6

Putting a = 8

[tex]|a-5| =5-a \\ |8 - 5| =5-8 \\ |3| = - 3 \\ 3 \cancel = - 3[/tex]

a is also not equal to 8

so above values we can find a common result that a not equal to value bigger than 5

picking random number

Putting a equal to 1

[tex]|a-5| =5-a \\|1-5| =5-1 \\ | - 4| =4 \\ 4 = 4[/tex]

a can be equal to 1

Putting a equal to -3

[tex]|a-5| =5-a \\| - 3-5| =5-( - 3) \\ | - 8| = 8\\ 8 = 8[/tex]

a can be equal to -3

So we can have a common result that a can be equal to values less than 5

putting a equal to 5

[tex]|a-5| =5-a \\ |5 - 5| =5-5 \\ |0| =0 \\ 0 = 0[/tex]

So we can say a can be equal to 5

is the answer...

for the line that goes up - it cuts the y-axis at - 5  (p = -5)

when we take 2 points we go from one to the other by going to the right of 1 unit and going up of 3 units (slope m : 3/1)

=> y = 3x - 5

and

for the line which goes down - it cuts the y-axis in +2 (p=2)

when we take 2 points we go from one to the other by going to the right of 2 units and going down of 1 unit (slope m : -1/2)

=> y = -1/2x + 2

=> y + 1/2x = 2

2x + 4y = 8

=> B

Reshmi bought more cloth by 4/15...

Step-by-step explanation:

1st equalize the denominator of 2/3 and 2/5

lcm of the denominators 3 and 5 is 15

2/3*5/5=10/15

2/5*3/3=6/15

Rashmi bought 10/15 m cloth

madhu bought 6/15 m cloth .

therefore, Rashmi bought more cloth

by how much more?

10/15-6/15 = 10-6/15=4/15

therefore, reshmi bought more cloth by 4/15

average speed= total distance/total time taken

60+45= 105miles

1 mile= 1.609

105×1.609= 168.945km

168.945/4

Hence answer = 33.79 km/hr

Answer:

To find Alex's average speed for the whole journey, we can use the formula:

Average Speed = Total Distance / Total Time

Let's calculate the total distance traveled first:

Distance1 = 60 miles/hour * 3 hours = 180 miles

Distance2 = 45 miles/hour * 2 hours = 90 miles

Total Distance = Distance1 + Distance2 = 180 miles + 90 miles = 270 miles

Next, let's calculate the total time taken for the whole journey:

Total Time = 3 hours + 2 hours = 5 hours

Now, we can find the average speed:

Average Speed = 270 miles / 5 hours = 54 miles per hour

So, Alex's average speed for the whole journey is 54 miles per hour.
