Answer:
Step-by-step explanation:
2) let the two numbers be x and y
x-y =15
(taking x to be big)
x = 3 (y)+1
i.e. x-3y =1
Subtracting we get
2y =14 or y =7
x =15+7 =22
Larger number is 22 and smaller number is 7

Alysha is 2 years younger than Bryce/
Let Alysha be x years old then Bryce would be x+2
Sum of their ages
=x+x+2 =28
2x+2 =28
2x=26
x=13
Hence Alysha is 13 years old and Bryce 14 years old.

Given:
1st week: caught 45 salamanders and put leg bands on them
2nd week: caught 50 salamanders and 3 have leg bands
3/50 = 0.06 of the salamander population have leg bands.
45 / 0.06 = 750 total number of salamanders
<span>45/750 = 0.06 or 6% </span>
The reasonable estimate of the number of salamanders by the pond is 750 salamanders.
