Given- r-2t and t-3We need to find value of 2rSubstitute the value of t in-xA0-r-2t-x2234-r-2-3-6-x2234-r-6If-xA0-r-6- then-xA0-2r-2-6-12-x2234-2r-12-Hence- option E is correct-

If $r = 2 t$ and $t = 3$ , what is the value of $2 r$ ?
$8$
$4$
$2$
$6$
$12$

Given, $r = 2 t$ and $t = 3$
We need to find value of $2 r$
Substitute the value of $t$ in $r = 2 t$
$∴ r = 2 (3) = 6$
$∴ r = 6$
If $r = 6$ , then $2 r = 2 (6) = 12$
$∴ 2 r = 12$ .
Hence, option E is correct.

If r=2t and t=3, what is the value of 2r?842612

Given, r=2t and t=3We need to find value of 2rSubstitute the value of t in r=2t∴r=2(3)=6∴r=6If r=6, then 2r=2(6)=12∴2r=12.Hence, option E is correct.
