Answer: B
Explanation: if you look at A and try to combine like terms, you will add the -x on the right side the the one on the left, cancelling out the x on the left. then you have 0=x+0, and unless x=0, it is not true.
With B, when you add x to the -x, you cancel it out, giving you 0=0, which is true. hope it helps!
Answer: = 264/10000 = 0.0264 = 2.64%
Step-by-step explanation:
The probability that a randomly chosen senior does not plan to attend college immediately following high school and plans to major in Math =
Pa × Pb
Where Pa = The probability that a randomly chosen senior does not plan to attend college immediately
Pb = The probability that a randomly chosen senior who does not plan to attend college immediately following high school plans to major in Math
Pa = 100% - 78% = 22%
Pb = 12%
P = Pa × Pb
P = 22/100 × 12/100
P = 264/10000
P = 0.0264
P = 2.64%
Answers
Number of nickels = 16
Number of quarters = 8
======================================================
Work Shown
The nickels, dimes and quarters are in the ratio 2:2:1 which means we have 2x nickels, 2x dimes and 1x quarters for some positive whole number x.
We have 16 dimes. Set 2x equal to 16 and solve for x.
2x = 16
x = 16/2
x = 8
S = large shrimp and p = popcorn shrimp
s + p = 10.....multiply by -1
5s + p = 30
---------------
-s -p = -10 (result of multiplying by -1)
5s + p = 30
---------------add
4s = 20
s = 20/4
s = 5
s + p = 10
5 + p = 10
p = 10 - 5
p = 5
so there was 5 lbs of large shrimp (s) and 5 lbs of popcorn shrimp (p) in the mixture
Slope = (y2 - y1)/(x2 - x1) = (-61 - (-37))/(-32 - (-26)) = (-61 + 37)/(-32 + 26) = -24/-6 = 4
Therefore, slope = 4
