Your answer is 0.03 because you have to make the 5 equal to the ten and that would be 10 then change the division to multiplication and just multiply across then you simplify it.
Answer: y = 8
Step-by-step explanation:
Answer:
each notebook costs $2.70
each pack of pencils costs $1.50
Step-by-step explanation:
system of equations:
let p = pack of pencils
let n = notebook
3p + 5n = 18
4p + 4n = 16.8
I used the elimination method by multiplying the first equation by 4 and the second equation by -3
4(3p + 5n = 18) = 12p + 20n = 72
-3(4p + 4n = 16.8) = -12p -12n = -50.4
adding the new equations together you get: 8n = 21.6
n = 21.6/8
n = $2.70
solve for 'p':
3p + 5(2.7) = 18
3p + 13.5 = 18
3p = 4.5
p = $1.50
Answer:
1st One goes to the third one
2nd one goes to the 1st one
3rd one goes to the 4th one
and the 4th one goes to the 2nd one
Answer:
=25343 grams or 25 kg 343 g.
Step-by-step explanation:
1 kg = 1000 g
∴ 4 kg = 4000 grams
and the 4 kg 250 g would equal = 4250 grams.
∴ 2 kg = 1000 g
2 kg 90 g = 2000 grams + 90 g = 2090 grams
∴ 19 kg = 19000 grams
and 19 kg 3 grams = 19000 grams + 3 grams = 19003 grams
now we will add all of the values together to get the final answer.
4250 grams + 2090 grams + 19003 grams = 25343 grams or 25 kg 343 g.
Hope this helps!!
