There are 3 people. The ratio of their ages is 2:3:4. In two years time their ages will be in the ratio 9:13:15. How old are they now?​

Answers

Answer 1

The ages of the 3 people are 2, 3, and 4 years respectively.

Let us assume that the ages of the 3 people are x, y, and z. We can form the following equations based on the given information;The ratio of their ages is 2:3:4:

Thus, x:y:z = 2:3:4 ------(1)

In two years' time, their ages will be in the ratio 9:13:15:

Thus, (x+2):(y+2):(z+2) = 9:13:15 -------(2)

From equation (1), we know that:x = 2k, y = 3k and z = 4k (where k is a constant)

Substituting these values in equation (2) and solving for k, we get;k=1

Therefore, x = 2k = 2, y = 3k = 3, and z = 4k = 4

So, the ages of the 3 people are 2, 3, and 4 years respectively.

The total age of the 3 people is 2+3+4 = 9 years.

46 degrees for both b and c

Answer:

46 degrees for both b and c

Step-by-step explanation:

the vertical angles postulate means that the opposite angle must be the same, so 134*2=268

since all angles must be 360, subtract 268, which is 92

using the vertical angles again, b and c are the same, and the sum must be 92

92 divided by 2 is 46

Adult tickets to a play cost $22 tickets for kids cost $15. Tickets for a group of 11 cost a total of $228. How many children and how many adults went to the play?

Answers

Answer:Number of children = 2 and number of adults = 9 attended the play

Step-by-step explanation:

Step 1

Let the  number  of children be represented as  x

and the number of adults in the group  be represented as  as y

such that the total number of the group that went to the play

= x+y=11--- equation 1

And the total cost paid for the play will be expressed as

15x+  22y= 228------ equation 2

Step 2-- Solving

x+y=11--- equation 1

15x+  22y= 228------ equation 2

B y elimination method, multiply equation 1 by 15 to give equation 3  and then subtract from equation 2

15x+  22y= 228------ equation 2

15x+15Y= 165----- equation 3

7y=63

y= 63/7= 9

y= adults = 9

therefore x = number of children will be

x+y=11

x+ 9=11

x= 11-9= 2

In the group that attended the play,  Number of children = 2 and number of adults = 9
