We have such equation
53=12(m-3/4)-16
First we have to multiply 12 times every argument from the parethesis.
53=12*m*-3/4*12-16
53=12m-9-16
53=12m-25 /+25 (add 25 both sides)
53+25=12m
78=12m /:12 (divide both sides by 12)
78:12=m
$\frac{78}{12}=m$
$\frac{13}{2}=m$
6.5=m - its the answer

53=12(m-3/4)-16 is solved below:

First,
You must multiply 12 by m and 12 by -3/4(0.75) which is 12m and -9

Second,
12m - 9 - 16 ~~Combine Like Terms And It Will Become 12m + 25
53 = 12m + 25 ~~ You Must Subtract 25 From Both Sides Of The Equation And It Becomes 28 = 12m

Third,
28 = 12m ~~divide both sides by 12
12 12 ~~ 12m/12 cancels out and 28/12 is 2

Therefore Your Answer is 2

Jam world amusement park sells special multi-day passes for guest who want to visit the park for more than a day there most popu

Answer:

The 3-day pass costs $16.67 more per day than the 7-day pass.

Step-by-step explanation:

The easiest way to do this is to find the cost of each pass for the same amount of days. To do this, we find the lowest common multiple of 3 and 7 which would be 21

Lowest common multiple = $7*3 = 21$

Next we find the cost of each pass for 21 days by multiplying cost of the 7 day pass by 3, and the cost of the 3 day pass by 7

Cost of 7 day pass for 21 days = $364*3 = 1092$

Cost of 3 day pass for 21 days = $206*7=1442$

From this, we know that the difference between the two passes is $350 per 21 days. Since the question asks how much more would the 3-day pass cost per a day than the 7-day pass, we have to divide the difference by 21

$350/21 = 16.66667$
