NEED HELP ASAP! Triangles RST and UVW are similar. Find the missing side y? A.) 10.965
B.) 11.345
C.) 10.15

Explanation:

RS and UV are the first two letters of RST and UVW respectively. So that means RS corresponds to UV to form the ratio RS/UV.

RT and UW are the first and last letters of RST and UVW. So we have RT/UW as another ratio. This ratio is equal to the first ratio we found since the triangles are similar. Similar triangles have their corresponding sides be in proportion with one another.

So we can form this equation

RS/UV = RT/UW

Let's apply substitution and solve for y

RS/UV = RT/UW

10/(14.5) = 7/y substitution

10*y = 14.5*7 cross multiply

10y = 101.5

y = 101.5/10 dividing both sides by 10

y = 10.15

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
