Maddi went to the store and bought 5 packs of gummy bears and 2 drinks for a total of $5.84. stephen went to the same store and bought 2 packs of gummy bears and 8 drinks for a total of $10.40. write and solve a system of equations and use it to determine the cost of gummy bears and drinks.(part 2) aaron went to the same store and bought 2 packs of gummy bears, 4 drinks and picked up a gallon of milk. how much did he spend if the milk cost $4.07?

5x+2y = 5.84 is the equation for maddi.

2x+ 8y =10.40 is the equation for stephen.

set them equal and then cancel them out! if you do that you can plug it into the part 2 equation which is

2x+4y+z=4.07

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
