To rearrange you must first simplify
aq-ac=d
add ac to each side:
aq=d+ac
then divide by a:
q=(d/a)+c and this is your answer
The question is asking how many combinations of two people can be made from a group of ten people.
Using the formula C(10,2) = 10!/(2! x (10 - 2)! = 10!/(2! x 8!) = 45 handshakes.
A simple way to prove this is each person shakes the hand of 9 other people
10 x 9 = 90 but this counts every handshake from the view of both people involved.
The actual number of handshakes is therefore 90 / 2 = 45
so what you do is distribute the 0.9 to x and 1.4 to get 0.9x+1.26 then combine like terms 1.9x - 1.04= 1.6 then add 1.04 to both sides to get 1.9x = 2.64 divide 1.9 to both sides
answer:1.389 and if you round 1.39
Answer:
124 in^2
Step-by-step explanation:
Please see the attached image.
The area of the rectangle is 6*14=84
The area of the triangle is (8*10)/2=40
The total area is the rectangle plus the triangle, so 84+40=124 in^2.
I assume that the question for this one is
<span>"What Relation Is a Doorstep to a Doormat?"
The correct answer for this question is that the doorstep's relation to a doormat is disjoint exclusive. The doorstep can still be there without the doormat; and the doormat can exist without the doorstep. So, we can say that they are disjoint.</span>
