Answer:
where
Step-by-step explanation:
Solution:
we have been asked to find
If you ran exactly one mile, how many feet did you run.
It mean , we will have to convert miles in feet.
As we know that
1 mile is equivalent to 5280 feet.
Hence , we can use this conversion to get the exact value of miles in feet.
If you ran exactly one mile,it mean you ran exactly for 5280 feet.
C + a = 140......a = 140 - c
5.3c + 9.4a = 1086.4
5.3c + 9.4(140 - c) = 1086.4
5.3c + 1316 - 9.4c = 1086.4
5.3c - 9.4c = 1086.4 - 1316
-4.1c = - 229.6
c = -229.6 / -4.1
c = 56......so their were 56 child tickets sold
X is equal to 45 because the whole thing is supposed to equal 180
Think of it as a subtraction problem.
-3x -4y = -1
3x - y = -4
_________
0x -5y = -5
y = -5/-5 = 1
Plug 1 in for y in either of the equations
3x -1 = -4
3x = -3
x = -1
Answer: (-1, 1)
