n-25.4=-44.8 To solve it you need to first add 25.5 on both sides. Then you need to line up your decimals. Next you have to check your interger rules and because the signs are different you subtract in instead of adding. So when you subtract -44.8-25.4 you get -19.4.

Y-23=-37 Y+5=-9 Y÷7=-91 Y19=

Bob and Sally were running and resting on way to the park to have a picnic. They started at there house and ran 3 miles and then they took 30 minute a break. After the break they dicited to run a 1.5 more miles and took a 15 minuite break when they noticed that they forget there lunch so they had to run back to there house.
