Answer:
<h2>
<u>318</u></h2>
Step-by-step explanation:
13 693:n=x, remainder 19 => 13 693=n*x+19
17 191:n=y, remanider 19 => 17 191=n*y+19
n>19
13 693-19=n*x
17 191-19=n*y
13 674=n*x
17 172=n*y
n=(13 674; 17 172)
13 674 = <u>2</u>*<u>3</u>*43*<u>53</u>
17 172=<u>2</u>²*<u>3</u>⁴*<u>53</u>
<em><u>n=2*3*53</u></em>
n=318
Answer:
15%
Step-by-step explanation:
set up 15/20= x/100
cross multiply to solve for x
1500=20x
x= 75
15 dollars is 75% of the original price, so there was a 15% change
x and x+4 are the numbers
3x=2(x+4)
3x=2x+8
3x-2x=8
x=8
x+4=12
