The sum of two numbers is 153. if four times the smaller number is subtracted from the larger number, the result is 18. find th

sleet_krkn [62]

X = larger number and y = smaller number

x + y = 153....x = 153 - y
x - 4y = 18

153 - y - 4y = 18
153 - 5y = 18
-5y = 18 - 153
-5y = -135
y = -135/-5
y = 27 <=== smaller number

x - 4y = 18
x - 4(27) = 18
x - 108 = 18
x = 18 + 108
x = 126 <== larger number

Determine whether the polygons are similar. If so, identify the correct similarity ratio and the similarity statement. HELP ASAP

Vilka [71]

Answer:

No, the triangles are not similar

Step-by-step explanation:

The (reduced) side length ratios, shortest to longest, are ...

12 : 18 : 20 = 6 : 9 : 10

and

5 : 12 : 13

These are not the same, so the triangles are not similar.
