Let x = number of miles, cost per mile = 82 cents = $0.82
Cost = 19.95 + 0.82*x
178.21 = 19.95 + 0.82x
0.82x + 19.95 = 178.21
0.82x = 178.21 - 19.95
0.82x = 158.26
x = 158.26/0.82
x = 193
<span>He drove 193 miles. </span>
That would be C.
20x + 5y = 50
5y = - 20x + 50
y = -20/5x + 50/5
y = - 4x + 10
now in y = mx + b form. the m represents ur slope and the b represents ur y intercept. So here, u have a slope of -4 and a y intercept of 10.
Answer: One possible expression that has a solution of 9 is: (3x12)-(27+0)
Step-by-step explanation: You most likely will have to find 9 as a solution using the 4 numbers you are given:
3 0 27 12
One way to have 9 as a solution could be: (3x12)-(27+0)
Lets solve this possible way: 3x12=36 and 27+0=27. All we have to do now is subtract 36 from 27. 36-27=9
So, (3x12)-(27+0)=9 is a possible solution.
N would be equal to -1, so the last pair of parentheses would be (6,-1).
