PR =25, PQ=7, so QR = PR - PQ = 25-7 =18

SQ=2x+5, TQ=6

Here we use the chord intersection formula, which will give

PQ*QR = SQ*TQ

7*18 = 6(2x+5)

126 = 12x +30

Subtracting 30 from both sides

96 = 12x

Dividing both sides by 12

8=x

So the value of the x is 8 .

While traveling to the office, dolly drives her car at a speed of 60 kmph and then suddenly the car stopped on half of her dista
lisabon 2012 [21]

The average speed of Dolly is 33.33kmph.

Average Speed:

The average speed is defined as the total distance travelled by the object in a particular interval of time. It can be calculated by dividing the total distance travelled by the total time taken.

So, Average Speed = total distance / total time

Here,

Let the total distance is 100 km.

Therefore, consider she will travel 60 km at speed of 60 kmph , 30 km at speed of 30 kmph and 10 km at speed of 10 kmph.

she will required times of 1 hour, 1hour and 1hour

So,

Average speed = 100 / (1 + 1 + 1)

=> 100 / 3 = 33.33

Determine The number of solutions 3(x-4)=2x+6
Trava [24]

Answer:

The answer will be listed below.

Step-by-step explanation:

First of all, you want x to by itself, so distribute the three to both x and negative 4 so you'll get 3x-12=2x+6.

Now, subtract 2x from both sides and add 12 to both sides and you'll get an answer of x=19. From that, you are able conclude that this equation has one solution.

Match the inequality with its line graph.
Flura [38]

Answer:

Here, answer is given in form of 4 figure labelled with inequality

Step-by-step explanation:

Given inequality are

A). 2x>(-6)

B). 6+x\leq 3

C). x-4

D). -x-5\leq (-2)

For matching with givens graph:

Simplifying...

A). 2x>(-6)

Divide 2 on both sides

x>(-3)

B). 6+x\leq 3

Add (-6) on both side.

6+x+(-6)\leq 3+(-6)

x\leq(-3)

C). x-4

Add (4) on both side.

x-4+4

x

D). -x-5\leq (-2)

Multiple (-1) on both side

+x+5\geq (+2)

Note :  Change of inequality sign due to multipication of negative number

Add (-5) on both side.

x\geq (-3)

Here, Answer is given in form of 4 figure labelled with inequality
