Answer:

-4 is the correct ans

hope it helps

Step-by-step explanation:

[tex] \tt{6 = 2 - k}[/tex]

~Swap the sides of the equation

⟶ [tex] \tt{2 - k = 6}[/tex]

~Transpose 2 to right hand side and change it's sign

⟶ [tex] \sf{ - k = 6 - 2}[/tex]

~Subtract 2 from 6

⟶ [tex] \tt{ - k = 4} [/tex]

~Divide both sides of the equation by -1

⟶ [tex] \tt{ \frac{ - k}{ - 1} = \frac{4}{ - 1}} [/tex]

⟶ [tex] \tt{k = - 4}[/tex]

[tex] \pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{k = - 4}}}}}}}[/tex]

Answer:

w=82

Step-by-step explanation:

7=w5

Answer:

The value of w is -166.

Step-by-step explanation:

☆Let's solve the equation

[tex] \: \: \: \: 7 - w = 173 \\ \frac{ - 7 \: \: \: \: = - 7}{-1w = 166} [/tex]

Answer:

Step-by-step explanation:

1. As you can see in the picture, x is 116 degrees, because that angle and the angle labeled 116 degrees are corresponding, meaning that their angles are the same.  

2. As you can also see in the picture, y+11+x = 180 deg, because they are two angles that make a straight angle. We know that x is 116 deg, so we can solve y with an equation:

y + 11 + 116 = 180

y + 127 = 180

y = 180 - 127

y = 53 degrees.

Step-by-step explanation:

This question is incomplete; here is the complete question.

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.

If it continues to fall at this rate, what will the temperature be:

In 2 hours ............. In 5 hours .............. In half an hour......................

If the current temperature of the mountain is b°C and it is falling at a constant rate of 3°C per hour.

Then after 'x' hours, temperature on the top of the mountain will be represented by the function,

T(x) = 0 - 3x

Therefore, temperature after 2 hours = -3(2) = -6°C

Temperature after 5 hours = -3(5) = -15°C

Temperature after half an hour = [tex]-3(\frac{1}{2})[/tex]

                                                    = -1.5°C

Answer:

Option C i.e. 10 miles is true.

Step-by-step explanation:

From the graph, it is clear that:

The art gallery is located at x = 7 and y = 2

The dry cleaners is located at x = 7 and y = 7

The theater is located at x = 2 and y = 7

Given that each unit is 1 mile.

Distance from the art gallery to dry cleaners is on the vertical path.

so

Distance from art gallery to dry cleaners = 7 - 2 = 5 miles

As Theater and dry cleaners are on the horizontal path.

Thus, in order to move to the theater from dry cleaners, all we need is to count the unit on the x-axis from x = 7 to x = 2.

i.e. 7 - 2 = 5 miles

Thus, the total distance: 5 + 5 = 10 miles

Therefore, option C i.e. 10 miles is true.

Step-by-step explanation:

The algebraic expression is

(x²+ 7x+10/ x²+ 4x+4 ) (x²+ 3x+2/x²+ 6x+5)

The options are                                               Arrangement

a.(x+5/x+2) * ( x+2/x+5)                                             Number 2

b.(x+7/x+4) ( x+1/x+2)

c.    1                                                                            Number 4

d.   (x+5) ( x+2) /(x+5)

e.  (x+7) (x+1)/(x+4) ( x+1) * (x+3) (x+1)/(x+3) (x+2)

f. (x+2) (x+5)/(x+2) ( x+2) * (x+1) (x+2)/(x+5) ( x+1)       Number 1

g. x+2

h.(x+5/x+2) ( x+2/x+5)                                               Number 3

Answer

Factorizing the expressions (x²+ 7x+10/ x²+ 4x+4 ) (x²+ 3x+2/x²+ 6x+5)

=(x²+ 5x+2x+ 10/ x²+ 2x+2x+4 ) (x²+ 2x+x+ 2/x²+ 5x+x+5)

Taking common

=[x(x+5) +2(x+5)/ x(x+2) +2(x+2) ] [ x(x+2) +1(x+2)/ x((x+5) +1(x+5)]

Putting commons together

=[(x+2) (x+5)/ (x+2) (x+2)] [ (x+2)(x+1)/ (x+1) (x+5)]

Cancelling

= [ (x+5)/ (x+2)]* [ (x+2)/  (x+5)]

=[ (x+5)/ (x+2)] [ (x+2)/  (x+5)]

Again Cancelling

=1

The above question is solved in 4 steps :

Step 1

(x+2) (x+5)/(x+2) ( x+2) * (x+1) (x+2)/(x+5) ( x+1)

Step 2

(x+5/x+2) * ( x+2/x+5)

Step 3

(x+5/x+2)  ( x+2/x+5)

Step 4

1   which is the answer .

The steps

(x+7) (x+1)/(x+4) ( x+1) * (x+3) (x+1)/(x+3) (x+2) ,

(x+5) ( x+2) /(x+5),  

(x+7/x+4) ( x+1/x+2) and (x+2) are not related to this question.

Interest Charge = $606.06

Step-by-step explanation:

Cost for 24 days = 600 + 24*0.0004205*600

Cost(24) = (1+24*0.0004205)600

Cost(24) = 1.010092*600 = $606.06

Answer:

0.35km

Step-by-step explanation:

What is equivalent distance of 35,000 centimeters in kilometers?

Given the following

1 km = 1000 m

1 m = 100 cm

If

1 m = 100 cm

x = 35000cm

100x = 35000

x = 35000/100

x = 350m

Convert 350m to km

1 km = 1000 m

x = 350m

1000x = 350

x = 350/1000

x = 0.35km

Hence 35000cm to km is 0.35km

Answer:

7/16π

Step-by-step explanation:

The surface area of the snow ball = 4πr^2

Let the surface area= y

Then y= 4πr^2

The derivative can be taken with respect to time as

dy/dt= (8πr)dr/dt...........eqn(1)

We were told that its surface area decreases at a rate of 7 cm2/min.

Then dy/dt=-7

diameter = 8 cm. cm/min, the radius r= 4cm/min

r= 4

Substitute the values of r into eqn(1)

dy/dt=(8π×4)dr/dt

-7=(32π) dr/dr

dr/dt= -7/32π................eqn(**)

But we know that diameter d= 2× radius

d=2r............eqn(*)

We can find the derivatives with respect to t as

dd/dt=2dr/dt

Then substitute en(**) we have

dd/dt=2(7/32π)

dd/dt= -14/32π

Divide both numerator and denominator by 2

dd/dt= -7/16π

Hence, the diameter decreases by the rate of 7/16π
