A carpenter bought 750 nails. Each nail has a mass of 5.2×10−3 kilogram. What is the total mass, in kilograms, of the nails the
lawyer [7]

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 5.2 \times 10^{-3} 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 = 5.2 \times 10^{-3} kilogram

total mass of the nails bought = number of nails bought x mass of each nail

\text {total mass of the nails bought }=750 \times 5.2 \times 10^{-3}

\text {total mass of the nails bought }=3900 \times 10^{-3}=\frac{3900}{1000}=3.9

Thus the total mass of nails bought is 3.9 kilogram

A + c = 405 <br> 12a + 5c = $3,590
SOVA2 [1]

Answer:

a=223.57

c=181.43

Step-by-step explanation:

a=405-c

substitute for a in the equation :

12a+5c=3590

12(405-c)+5c=3590

4860-12c+5c=3590

-7c=3590-4860

-7c=-1270

c=1270/7=181.43

a=405-1270/7

a=1565/7=223.57
