Answer:

adult=10

Child=7

One adult and one child=10+7=17

Step-by-step explanation:

Let a be the price of an adult ticket

c = price of the child ticket

2a+4c = 48

5a+2c = 64

Multiply the second equation by -2 and add to the first equation

2a+4c = 48

-10a-4c = -128

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

-8a +0c = -80

Divide by -8

-8a/-8 = -80/-8

a = 10

Now find c

2a+4c=48

2(10)+4c=48

20+4c=48

4c=48-20

4c=28

4c/4=28/4

c=7

If f(2) = 22 – 5, then what is the value of f(2) + f(5)?
jasenka [17]

Answer:

67

Step-by-step explanation:

With the information of f(2) = 22-5,  you can assume the equation will be f(x) = 11x-5. Using this, you can calculate f(5) by doing 11(5)-5, which is 50. 22-5 is 17, so 50+17=67

A girl ran to the store at a speed of 6mph, and walked back at 4mp. If her round trip took 15 minutes, how far away is the store
MariettaO [177]

Answer:

0.6 miles

Step-by-step explanation:

Let's say the store is x miles away, she walks to the store in a hours, and she walks back in b hours.

First, her total time = time walked there + time walked back = a + b = 15 minutes = 1/4 of an hour = 0.25 hours

a + b = 0.25 (because a and b are in hours)

distance = speed * time

x = 6 miles/hour * a hours = 6a miles

x = 4 miles/hour * b hours = 4b miles

If we can find a or b, we can find x.

4b = x = 6a

4b = 6a

a + b = 0.25

We now have two equations with two variables. Using substitution, we can solve for one of them

a + b = 0.25

subtract a from both sides to find b

0.25 - a = b

plug that into the other equation, 4b = 6a

4(0.25-a) = 6a

1 - 4a = 6a

add 4a to both sides to isolate a and its coefficient

1 = 10a

divide both sides by 10 to solve for s

a = 1/10 of an hour = 0.1 of an hour = 60 minutes / 10 = 6 minutes

6a = x

6(0.1) = x

0.6 = x

the store is 0.6 miles away
