Answer:
QR = 82.38 to nearest hundredth.
Step-by-step explanation:
As they are similar corresponding sides are in the same ratio.
So MN / QR = LM / QR
13/51 = 21/ QR
`3QR = 51*21
QR = 51*21/13
QR = 82.38
The absolute value - or distance from zero, is fairly simple to find. Make your final answer positive to find it.


Less than means to subtract so 2678 less than 10000 will be
=10000-2678
=7322
Yes they do, in the grand aspect of things.
