Answer:
a = b = 1
Step-by-step explanation:
The triangles are similar thus ratios of corresponding sides are equal, that is
= 
( cross- multiply )
10b = 10 ( divide both sides by 10 )
b = 1
and
= 
( cross- multiply )
10a = 10 ( divide both sides by 10 )
a = 1
Thus a = 1 and b = 1
Answer:
I don't have the explanation however I did this equation like months ago and I believe it's "the number of miles"
4r^2=4 if r=1
2s^3=250 if s=5
126/10 would mean that from the original number, the decimal point is at 126.0 so when it is divided by 10, it will move over one placement, making it 12.6... I would estimate that your answer is C. 12.6
Y - 2 = 5/4 ( x - 4 )
or
y = 5x/4 - 3
