5t = 25+2r
t = (25+2r)/5 or
t = 5 + (2/5)r
Answer:
9) C. 35 + 0.12x = 44.36
10) B
11) A. 32
Step-by-step explanation:
9)
44.36 is the TOTAL so the equations have to EQUAL it.
PER mile means it's a variable so it's 0.12x:
35 is a constant so there's no variable attached:
35 + 0.12x = 44.36
10)
B because you have to cancel the y values and to do that, you multiply the 1st equation by 3.
11)
0.1x + 0.25(46 - x) = 6.70
0.1x + 11.5 - 0.25x = 6.7
-0.15x = 6.7 - 11.5
-0.15x = -4.8
x = 32

Answer:
150 degrees
Step-by-step explanation:
Use the equation below to find the sum of all the interior angles in this polygon:
(number of sides - 2)*180
number of sides = 6
(6-2)*(180) = 4*(180) = 720
Now that you know the total sum, subtract all other angles to find x:
720 - 90 - 162 - 101 - 96 - 121 = 150
Answer:
$ 710606.606
Step-by-step explanation:
Let original price be x
x - 34% of x = 469000
=> X - 34x/100 = 469000
=> 100x -34x/100 = 469000
=> 66x/100 = 469000
=> 66x = 46900000
=> X = 46900000/66
=> X = 710606.606
