Answer:

a+c =11

a +3c = 19

a =7  and c = 4

Step-by-step explanation:

Let a = price of one adult

c = price of one child

We know one adult and one child = 11

a+c =11

Mrs smith and 3 children spent 19

a +3c = 19

We have 2 equations and 2 unknowns

a+c =11

a +3c = 19

Multiply the first equation by -1 so we can eliminate a

-a-c=-11

a+3c=19

----------------

2c = 8

Divide by 2

2c/2 = 8/2

c=4

Each child equals 4 dollars

Now we need to find a

a + c= 11

a+4 = 11

Subtract 4 from each side

a+4-4 = 11-4

a = 7

The adult is 7

Select Proportional or Not Proportional to correctly classify each pair of ratios. 3/7 and 8/28

3/7 is not proportional because if you divide 3 by 7 you don’t get a whole number or nice fraction



8/28 is proportional because if you divide the fraction by 4 you get 2/7 which is a nice fraction

Which number is in the domain of f(x)
MAXImum [283]
We should first find where the graph doesn't exist, which would be where the denominator is equal to 0 or the formula under the radical is negative. So we can write the equation x-3≤0 to find where the graph can't exist
x-3≤0
x≤3

So this means that no x values less than or equal to 3 can exist on this graph. So the only choice that isn't less than or equal to 3 is choice 2 (7)

Hope this helps
