The total mass, in kilograms, of the nails the carpenter bought is 3.9 kilogram
<h3><u>Solution:</u></h3>
Given that carpenter bought 750 nails
Each nail has a mass of
kilogram
To find: total mass, in kilograms of the nails bought
The total mass of the nails bought can be found out by multiplying number of nails bought by mass of each nail
Number of nails bought = 750
Mass of each nail =
kilogram
total mass of the nails bought = number of nails bought x mass of each nail


Thus the total mass of nails bought is 3.9 kilogram
It would be 10x10 =100 or in other word 10 times itself. Also known as 10 with the 2 hanging over the 10.
Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different. In an expression, only like terms can be combined. We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily.
It depends on how long the wedding is. Marvin has a $15 lower flat fee but a $4.50 more expensive hourly fee. Therefore, if the wedding is longer than 15/4.50=3.33 hours, it would make more sense to go with Dave. If the wedding is shorter than 3.33 hours, it makes more sense to go with Marvin.
