Mitch is saving money to go on a camping trip this summer. so far he has saved $160 which is 40% of the money needed to go on the camping trip. which equation below would one write to figure out the total amount of money mitch needs to save to go on the camping trip? a. 160/x = 40/100 b. 160/100 = 40/x c. 40/100 = x/160 d. 40/160 = x/100

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

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

25.45584

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

it is x equals 3   plese mark me really need it
