An iron bar has volume 650 cm' and density 7.87 g/cm3. Work out the mass of the iron. Give your answer in
a) grams
b) kilograms​

a.5115.5g

b. 5115.5/1000= 5.1kg

Step-by-step explanation:

Given data

volume= 650 cm^3

density= 7.87 g/cm^3

We know that

density= mass/volume

mass= density*volume

mass= 7.87*650

mass= 5115.5 g

a.5115.5g

b. 5115.5/1000= 5.1kg

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70

it's both, now can you answer my most recent question?
