Plz help. Less than 10mins to finish this a few others.
Elanso [62]

Answer:

RS = XY (since the two a triangles are similar, you have to match the sides up and then set the values equal to eachother to find the value of x)

3x +2 = 5x -3 (subtract 5x from both sides)

-2x +2 = -3 (subtract 2 from both sides)

-2x = -5 (divide both sides by -2 to isolate x)

x = 2.5 (take the value of x and plug it into the expression given for RS)

3(2.5) +2 (multiply)

7.5 +2 (add)

9.5 (this is the length of RS)

Step-by-step explanation:

I hope this helps :)

Twelve eggs cost $2.09.How much would 18 eggs cost?
Ostrovityanka [42]
12 egg=2.09
then your adding 6 more eggs to get 18 eggs and 6 is half of 12
so you would be adding half the price
2.09/2=1.05
so then add 2.09+1.05=3.14
So 18 eggs would be $3.14

Hope this helps!! :D
