▪︎If ten years ago , the age of daughter was x years , then , ten years ago the age of her father was 6x years ▪︎

Ten years after ,

According to the question,

▪︎6x + 20 = 2 ( x + 20 )

Therefore , Present age of the Father = 6x + 10 = 6 × 5 + 10 = 40 years and present age of the daughter,

hence , the age of his daughter is 15 years

b=+ac sqrt 3c

it's b=+ac sqrt 3c

Answer:

Step-by-step explanation:

Let the number of CD's = c

Let the number of tapes = t

Total  number of CD's and tapes = 9

c + t = 9   --------------- (i)

Cost of 'c' CD's = 7*c = 7c

Cost of 't' tapes = 6*t = 6t

Total cost = $ 68

7c + 6t = 58 -----------------(ii)

Multiply the first equation by (-6) and then add the equations.

(i)* (-6)       -6c - 6t = - 54

(ii)               7c + 6t =  58    {Now add. here t will be cancelled}

                   c         = 4

Number of CD's  = 4

Plugin c = 4 in equation (i)

4 + t = 9

     t = 9 - 4

     t = 5

Number of tapes = 5

Answer:

A = 73°

Step-by-step explanation:

A + B = 180 because of alternating interior angles

Substitute each angle

6x - 35 + 3x + 53 = 180

9x + 18 = 180

9x = 162

x = 18

Substitute A

A = 6x - 35

A = 108 - 35

A = 73

Hope this helps

Have a great day!

Answer:

A = 6

B = 10

Step-by-step explanation:

[] Let's look at the system again:

[tex]\left \{ {{Ax+By=38} \atop {2Ax-By=16}} \right.[/tex]

[] They give us a set of x and y values, (3, 2) so we can plug them into the system.

[tex]\left \{ {{A(3)+B(2)=38} \atop {2A(3)-B(2)=16}} \right.[/tex]

[] Now, we can solve this with a graphing calculator. Let A be x and B be y for the sake of graphing.

A = x

B = y

[tex]\left \{ {{x(3)+y(2)=38} \atop {2x(3)-y(2)=16}} \right.[/tex]

-> See attached

[] We can see the lines intersect at (6, 10) so the answer is A = 6 and B = 10.

Have a nice day!

Answer:

44%

Step-by-step explanation:

100 + 20 = 120/100

(1.2)^2=1.44

144 - 100 = 44%

since it's per annum, we'll assume is compounded interest.

Answer:

25 km

Explanation:

                                  Distance = speed * time

We have change time which are given in minutes to hour. As the speed is mentioned in kilometre per hour.

For part A:

[tex]\rightarrow Distance = speed * time[/tex]

[tex]\hookrightarrow Distance = 40 * \frac{15}{60}[/tex]

[tex]\hookrightarrow Distance = 10[/tex] km

For part B:

[tex]\rightarrow Distance = speed * time[/tex]

[tex]\hookrightarrow Distance =60 * \frac{15}{60}[/tex]

[tex]\hookrightarrow Distance = 15[/tex] km

Total distance covered:

part A + part B

10 km + 15 km

25 km

25 km

Speed of the car in first 15 mins ,

The car is moving in the speed of 40 km/h for 15 mins.

Speed of car in next 15 mins ,

again ,

now , total distance covered = ( 10 + 15 ) km = 25 km
