Answer: x = - 12
8x + 45 = 10x + 69
⇔ 10x - 8x = 45 - 69
⇔ 2x = -24
⇔ x = -12
Step-by-step explanation:
Answer:
The cost of parking the car for 1 hour = $2.5
Step-by-step explanation:
Cost of parking car for two hours = $5
Now, let the cost of parking the car for one hour be $x
Since, the car is parked for two hours and the cost charged is $5
So, each hour the cost of parking is same ⇒ Cost of parking one hour is half the cost of parking the car for two hours.
Since, the cost of parking the car for one hour = $x
So, cost of parking the car for two hours = 2x
But this cost is given to be $5
⇒ 2x = 5
⇒ x = 2.5
Hence, The cost of parking the car for 1 hour = $2.5
1) This sequence of numbers is arithmetic, because each number is the previous one divided by two.
2) the next number in the sequence is 125/2, which is 62.5
3x +2y= 11 ----1
x -2 = -4y ---- 2
Equation 2 times by 3
3x -6 = -12y
Subracting 2-1
3x-6=-12y
3x-11=-2y
Leaving
5=-10y
y= -1/2
Hence
B. is the solution
