Answer:
42 child and 70 adult
Step-by-step explanation:
Let a = number of adult tickets
c = number of child tickets
a+c = 112
2.25a + 1.75c = 231
Solve the first equation for a
a = 112-c
Substitute this into the second equation
2.25(112-c) + 1.75c = 231
Distribute
252 - 2.25c +1.75c = 231
Combine like terms
252 -.5c = 231
Subtract 252 from each side
252-252 -.5c = 231-252
-.5c = -21
Divide each side by -.5
-.5c/-.5 = -21/ -.5
c = 42
Now can find a
a = 112-c
a = 112-42
a = 70
Answer:
Upper
if your asking that kind of question
Step-by-step explanation:
Answer:
the slope is 1
Step-by-step explanation:
if you start at (0,0) and go up one and then right on the line lines up with the squares so since slope is
you go up one and the right one which makes it
so the answer is one.
Slope is also known as rise over run -

Here, we have the slope

. This means that the rise is

and the run is

. Since both values are positive, we can say that we go up one and we go right four. When we plot this on a graph (the graph is attached), we get the same exact formula we found. **In the graph, I plotted the line

**. Hope this helped!
