YesIf s is a multiple of 12- then so is 7s- If t is a multiple of 12- then so is 5t- Since 7s and 5t are both multiples of 12- then their sum -7s-5t- is also a multiple of 12-

If $s$ is a multiple of $12$ and $t$ is a multiple of $12$ , is $7 s + 5 t$ a multiple of $12$ ?
True
False

Yes
If $s$ is a multiple of $12$ , then so is $7 s$ . If t is a multiple of $12$ , then so is $5 t$ . Since $7 s$ and $5 t$ are both multiples of $12$ , then their sum $(7 s + 5 t)$ is also a multiple of $12$ .

If s is a multiple of 12 and t is a multiple of 12, is 7s+5t a multiple of 12?TrueFalse

YesIf s is a multiple of 12, then so is 7s. If t is a multiple of 12, then so is 5t. Since 7s and 5t are both multiples of 12, then their sum (7s+5t) is also a multiple of 12.
