General form of a linear equation is ax+by+c=0 where a,b, and c are three real numbers.
So, we can shift all the terms in one side of the equation. Hence, first step is to remove y from the left side. So, subtract y from each sides.
y-y=3x+2-y
0= 3x - y +2 (By simplifying)
So, the general form of the given equation is 3x-y+2=0.
The probability that none of the shoes are black is 51.2%.
If 20% of the shoes are black, then 80% of the shoes are not black. To find the probability that three shoes are not black, we have to multiply 80% by itself 3 times.
0.8 x 0.8 x 0.8 = 0.512 = 51.2%
The term for this is Hourly wage. This can be then used for calculating the gross annual salary.
hope this helps you.
A)
Increase %= (new # - old #)/old * 100
new= 8
old= 5
Increase %= (8-5)/5 * 100
=3/5 * 100
=0.60 * 100
=60% increase
B)
Decrease %= (old # - new #)/old * 100
new= 5
old= 8
Decrease %= (8-5)/8 * 100
= 3/8 * 100
= 0.375 * 100
= 37.5% decrease
ANSWER: a) 60% increase; b) 37.5% decrease
Hope this helps! :) Good luck on your test!!
