The answer is A. 3
If you please, mark brainliest ^^
Assuming a and b are parallel
<5 = <9 false
<1 = <12 false
<1 = <8 true
<3 = <7 true
Our first step is to get rid of the fraction by multiplying both sides by 3.
So in our second step we have x - 4 > -36.
Now add 4 to both sides to get <em>x > -32</em>.
Since <em>x</em> is greater than -32, the values that would
make this inequality true are -31 and 31.
Ratio 1:3 can be written as 1/3
sale price / original price : 1/3 = x / 81
this is a proportion, so we cross multiply
(3)(x) = (1)(81)
3x = 81
x = 81/3
x = 27 <== sale price
and notice that 1/3 = 27/81...these are equivalent fractions because that is what proportions are, equivalent fractions
