Corresponding sides have the same ratio.
(2a -5)/25 = 18/30
2a -5 = 25*18/30 = 15
a = (15 +5)/2 = 10
(3b +1)/15 = 30/18
3b +1 = 15*30/18 = 25
b = (25 -1)/3 = 8
a = 10
b = 8
Answer:
the answer would be 196.25
Step-by-step explanation:
Answer: y = 2x + 1
Step-by-step explanation:
use the equation y=mx+b where m is the slope and b is the y-intercept
y-intercept is 1
slope is 2, rise 2 run 1
213 because when you add them u you get 213
