From any proportion, we get another proportion by inverting the extremes (or the means):
= k
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=
= -
The corect answer is A. -3/2
or:
From any proportion, we get another proportion by inverting the extremes and the means:
We use a property of proportions:
where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),
so we have
or
(you can check this also by "the product of the extremes equals the product of the means")
3y = - 2x
The answer is 36 all you do is divide the answer choices by 3 to get your answer
First, we want to write an expression for what is given:
(1/5)(1/4)(1/9)(900)
Now, we can solve this. Remember that to multiply fractions, we can just multiply the numerators and the denominators. Also, whole numbers always have a denominator of 1.
(900/180)
=5
Answer:
49π
Step-by-step explanation:
The formula for the area of a circle is,
If the radius is 7 inches we need to plug that in for r in the formula.
π(7)^2
7*7 = 49
<em>Thus,</em>
<em>the area in terms of pi is 49π.</em>
