Gerald was able to mow 1/2 of a lawn in 12 minutes how many lawns could he mow in 2 hours

The answer would be 5. there’s 120 minutes in 2 hours. it takes him 12 minutes to mow half a lawn so you would do 120/12 which would equal 10. so that’s 10 lawns that are halfway mowed. so then you would do 10/2 which would equal 5.

It has a slope of 1 nd a y intercept of -2

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
