Answer: A3. The counting principle lets
you multiply
<span>The fundamental
counting principle is a method for determining how many ways that a combination
of events can occur. For example, if the
first event can occur 2 ways, the second event can occur 3 ways, and the third
event can occur 4 ways, then you can find out the number of unique combinations
by multiplying: 2 * 3 * 4 = 24 unique combinations.</span>
<span>This
multiplication method works any time you have several options or criteria like color,
shape, and design and each of those factors can be combined with each other in
any way possible. </span>
The main part of solving this problem is carefully looking at each and every word of the problem very minutely. The details required for solving the problem is already given in the question.
Let us assume the unknown number to be = x
Then the equation for getting to the unknown number can be written as
8x - 20 = x + 15
8x - x = 15 + 20
7x = 35
x = 35/7
= 5
So from the above deduction we can easily conclude that the unknown number in the question is 5.
Answer:
Hi! I'll do my best to explain for you.
-6(2x-3)+2x =0 First, set the equation equal to zero.
-12x+18+2x=0 Then, distribute the -6 by multiplying it with the -2 and -3.
-10x+18=0 Combine the like terms, which are -12x and 2x, to get -10x.
-10x=-18 You want to get the x on 1 side. Subtract 18 from both sides.
x=-18/-10 Divide by -10 on both sides.
x=1.8 Simplify the fraction. The answer is x=1.8.
I hope this helped!
