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.

in the product rule for exponents, what do you do to the coefficients? what do you do to the exponents?
Answer:
Do not multiply the coefficients and the exponents. Remember, using the Product Rule add the exponents when the bases are the same.
In the product rule of the exponents,
''For same base we can add the exponents of the coefficients.''
What is mean by expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Solve expression by using the product rule for exponents.
Now, We know that;
In the product rule for exponents;
When expression have same base then its exponents are add and the coefficients of expression are written as same as write in expression
Hence, In the product rule of the exponents,
''For same base we can add the exponents of the coefficients.''

Solve for angle 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

Neil has 2 pounds of grapes. He uses some to make a fruit salad. Now Neil has 8 ounces of grapes. How many ounces of grapes does Neil use for the fruit salad?
Answer:
Neil uses 24 ounces of grapes for the fruit salad.
Step-by-step explanation:
Quantity of grapes = 2 pounds
Use 1 pound = 16 ounces
So,
Quantity of grapes = 2(16) = 32 ounces
Neil uses some grapes to make a fruit salad. Now Neil has 8 ounces of grapes.
Quantity of grapes that Neil use for the fruit salad = [tex]32-8=24[/tex] ounces
Therefore,
Neil uses 24 ounces of grapes for the fruit salad.

The target number is 64 and the error is 1.5%
Possible number is
64 ± 1.5% of 64 = 64 ± 0.015*64
The top limit is:
64 + 64(0.015) or64*(1.015)Correct choices are B and F

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?
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
