Answer:

$y=\frac{3}{5} x+5$

Step-by-step explanation:

$5y-3x=25\\\\5y-3x+3x=25+3x\\\\5y+0=3x+25\\\\5y=3x+25\\\\\frac{1}{5} (5y)=\frac{1}{5} (3x+25)\\\\y=\frac{1}{5}(3x)+\frac{1}{5}(25) \\\\y=\frac{3}{5}x+5$

Find the smallest 3-digit number which gives the remainder 1 when divided by 3 and by 4.

trasher [3.6K]

Multiples of 3 plus 1 remainder are:

3n+1

Multiples of 4 plus 1 remainder are:

4n+1

Since these multiples must be the same number must be a multiple of 12 plus a remainder of one, which is:

12n+1

And the smallest such three digit number is:

12n+1>99 subtract 1 from both sides

12n>98 divide both sides by 12

n>8.17

Since n must be an integer, n=9

So then number is 12n+1

12(9)+1=109
