Evan is going to the country fair this weekend. the admission to the fair is $5 and the cost per ride is 50 cents. if his parents gave him $20 write and solve a linear equation to find how many rides he can go on

5x+0.50y=20

Step-by-step explanation:

A linear equation is an easier way to find a standard equation because it makes it easy to find x and y. So the equation would have to have x and y in it and this problem is 5 and 50 cents and his parents gave him the total which is 20 dollars so the equation would be

5x+0.50y=20

I am in middle school sorry if the explantion is bad

30 rides

Step-by-step explanation:

First subtract $5 from $20 (20-5) to get $15 now multiply 15 by 2 (which is the same as dividing by 1/2. and you get 30. so your answer is 30 rides

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
