Aqua town charges 4.50 admission plus 0.75 for each ride the cost at splash world is 2.50 admission plus 1.25 per ride let x represent the number of rides write an expression for each water park to show the relationship between the total cost and the number of rides

Total cost at Aqua town = 4.50+0.75x

Total cost at Splash world = 2.50+1.25x

Step-by-step explanation:

Total cost = Admission charge + Charge per ride x Number of rides

Let x= Number of rides.

Aqua town charges 4.50 admission plus 0.75 for each ride.

Total cost at Aqua town = 4.50+0.75x

Splash world is 2.50 admission plus 1.25 per ride.

Total cost at Splash world = 2.50+1.25x

The required expressions:

Total cost at Aqua town = 4.50+0.75x

Total cost at Splash world = 2.50+1.25x

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
