Answer: 45
Explanation:
When finding the equations for the numbers, remember that it is not three consecutive numbers: it is three CONSECUTIVE ODD numbers. Thus:
First number = x
Second number = x + 2
Third number = x + 4 (second number + 2)
x + x + 2 + x + 4 = 141
3x + 6 = 141
3x = 135
x = 45
This tells us that the smallest number (x) is 45. To check our answer, we can plug this value in for x:
45 + 45 + 2 + 45 + 4 = 141
141 = 141
This also tells us that the other two numbers would be 47 and 49, and 45 + 47 + 49 also equals 141.

Answer: Choice B</h3>
angle B = 118, a = 17, c = 18
==========================================================
Explanation:
Use the given angles to find angle B.
A+B+C = 180
B = 180-(A+C)
B = 180-(30+32)
B = 118
Now use the law of sines to find side 'a'
Make sure your calculator is in degree mode.
a/sin(A) = b/sin(B)
a/sin(30) = 30/sin(118)
a = sin(30)*30/sin(118)
a = 16.9885507603356
a = 17
Follow similar steps to find side c
c/sin(C) = b/sin(B)
c/sin(32) = 30/sin(118)
c = sin(32)*30/sin(118)
c = 18.005120638611
c = 18

Step-by-step explanation:
Because the electro has a smaller mass than the mass of the proton, scientific notation is usually used so that the numbers are on the same "scale" but if we see the scientific notation we may be able to identify which is greater and which is less, due to that the exponent is less the number is smaller and on the contrary if the number is greater, it is a larger number.

You just subtract the length of Kolby fish from Ellen fish length
10.995-4.335
= 6.660inches longer than kolby fish
