In number 2 there are 4 which are 22,x,3 and y. In number 4 there are 4 which are a,b,c and d.
<h3>
Step-by-step explanation:</h3>
<u>Step</u> <u>Property</u>
2x+6 = 22 given
2x = 16 addition property of equality (-6 added to both sides)
x = 8 multiplication property of equality (both sides × 1/2)
_____
In general equations are solved by reversing the steps done to the variable. Here, the variable (x) is multiplied by 2 and 6 is added to that product. So, to find x, we undo the addition of 6 (by adding -6, the additive inverse), and undo the multiplication by 2 (by multiplying by 1/2, the multiplicative inverse).
If other functions were performed on the variable in the original equation, their inverse functions would be used, too, as part of the solution process.
8 action, 3 comedy, 5 drama....total = 16 dvd's
P(2 action, then a comedy)...without replacement
8/16 * 7/15 * 3/14 = (8 * 7 * 3) / (16 * 15 * 14) = 168/3360 = 1/20
Here is how to work it with long division.
