Hello :
<span>the common ratio : r = 54/-18 = -18/6 = 6/-2 = -3</span>
First distribute invisble -1
-1(7x+3.5)=-7x-3.5
and distribute 3
3(x-2.5)=3x-7.5
now we have
10-7x-3.5=-5.75+3x-7.5
combine
6.5-7x=-13.25+3x
add 7x to both sides
6.5=-13.25+10x
add 13.25 to both sides
19.75=10x
divide both sides by 10
1.975=x
The answer is supposed to be that there is no solution
Answer:
$160
Step-by-step explanation:
Let the original cost of suit be x
If the suits were sold for $72 each and this price was 45% of a suit's original price, then;
72 = 45% of x
72 = 0.45x
x = 72/0.45
x = 160
Hence the original price of the suit is $160
