Let a be the amt of perfume A, and b be the amt of perfume B. We have been given that
<span>a+b=3</span> and that <span>a∗15+b∗35=63</span>
From equation 1, we substitute <span>b=3−a</span> so as to get, <span>a∗15+(3−a)∗35=63
</span> which means, <span>15a+105−35a=63</span> which means, <span>−20a=−42
</span><span> so a = 2.1 ounce and b = 0.9 ounce</span>

What is the mode of this data set? {41, 43, 45, 3, 11, 23, 24, 27, 29, 45, 12, 19, 22, 49, 25}
notka56 [123]
The mode of a data set is the number that appears most often...and just so u know, there does not have to be a mode...but in this problem there is....and the mode here is 45....it appears twice and all the other numbers appear once
Divition is the answer
Ex. a/b = a:b
They would be 69 and 70.
Your equation would be x + (x + 1) = 139
X would be the first integer and x + 1 would be the second
You would then solve the equation to get x as 69
X + 1 would then be 70
